CCS Certified Coding Specialist Exam — Questions and Answers

Question 1: Which standard is used to exchange health information electronically between disparate healthcare systems (e.g., hospitals and labs)?

DICOM
SNOMED CT
HL7 (Health Level Seven) (Correct answer)
X12 EDI

Correct answer: HL7 (Health Level Seven)

HL7 (Health Level Seven) is the international messaging standard used for exchanging clinical and administrative data between healthcare information systems.

Question 2: How does ICD-10-PCS handle bilateral procedures?

A single code with a bilateral qualifier is always used
Separate codes are assigned for each side, as body part values are side-specific (Correct answer)
A modifier is appended to indicate bilateral
The same code is listed twice on the claim

Correct answer: Separate codes are assigned for each side, as body part values are side-specific

ICD-10-PCS assigns side-specific body part values (right, left) or a bilateral value where it exists. When bilateral values are available, one code captures both. When not available, two codes are required.

Question 3: The ICD-10-CM 7th character 'A' used with injury codes designates:

Acute presentation requiring surgery
Sequela (late effect) of the injury
Initial encounter - patient receiving active treatment for the condition (Correct answer)
Subsequent encounter after the acute phase

Correct answer: Initial encounter - patient receiving active treatment for the condition

The 7th character 'A' designates 'initial encounter,' meaning the patient is receiving active treatment for the injury, regardless of whether it is the first visit.

Question 4: CPT codes are maintained and published by which organization?

American Health Information Management Association (AHIMA)
Centers for Medicare & Medicaid Services (CMS)
World Health Organization (WHO)
American Medical Association (AMA) (Correct answer)

Correct answer: American Medical Association (AMA)

The American Medical Association (AMA) owns, maintains, and annually updates the CPT code set.

Question 5: A coding quality review finds that coders are not coding all conditions that meet the UHDDS definition of 'additional diagnoses.' What is the MOST likely financial impact?

Increased audit risk from payers
Overpayment due to inflated DRG weights
Underpayment due to missed CC/MCC capture affecting MS-DRG assignment (Correct answer)
No impact since only the principal diagnosis affects reimbursement

Correct answer: Underpayment due to missed CC/MCC capture affecting MS-DRG assignment

Failing to code all valid additional diagnoses means CCs and MCCs may be missed, resulting in lower MS-DRG weights and underpayment for the facility.

Question 6: CPT modifier -59 is used to indicate:

A distinct procedural service not normally reported together but appropriate under the circumstances (Correct answer)
The patient refused part of the service
A procedure was performed by a different surgeon
The procedure was reduced due to extenuating circumstances

Correct answer: A distinct procedural service not normally reported together but appropriate under the circumstances

Modifier -59 identifies a procedure or service as distinct or independent from other services performed on the same day when other modifiers do not adequately describe the situation.

Question 7: Which SQL clause is used to filter results after a GROUP BY aggregation in a healthcare analytics query?

DISTINCT
HAVING (Correct answer)
WHERE
ORDER BY

Correct answer: HAVING

The HAVING clause filters grouped results, unlike WHERE which filters individual rows before grouping.

Question 8: Which of the following represents the correct hierarchy of source documents when conflicting information exists for determining the principal procedure on an inpatient claim?

Discharge summary, then nursing notes, then operative report
Physician orders, then discharge summary, then operative report
Nursing notes, then operative report, then discharge summary
Operative report, then procedure notes, then discharge summary (Correct answer)

Correct answer: Operative report, then procedure notes, then discharge summary

The operative report is the most authoritative source for surgical procedures, followed by procedure notes, then the discharge summary when discrepancies exist.

Question 9: Which of the following is a prerequisite for sitting for the CCS examination?

A minimum of 3 years of inpatient coding experience
A bachelor's degree in health information management
No formal prerequisites - the exam is open to all qualified candidates (Correct answer)
AHIMA membership

Correct answer: No formal prerequisites - the exam is open to all qualified candidates

AHIMA does not require AHIMA membership or specific formal education/experience prerequisites to sit for the CCS exam, though it strongly recommends coding experience and education.

Question 10: Which of the following best describes the purpose of the History and Physical (H&P) in the medical record?

To summarize the hospital course and outcomes at discharge
To record nursing assessments completed throughout the stay
To document the patient's medical history, review of systems, and baseline physical examination at admission (Correct answer)
To outline the discharge plan and follow-up instructions

Correct answer: To document the patient's medical history, review of systems, and baseline physical examination at admission

The History and Physical documents the patient's past medical history, current complaint, review of systems, and the physician's baseline examination findings at or near the time of admission.

Question 11: What is the passing score required for the CCS certification exam?

400
300 (Correct answer)
250
350

Correct answer: 300

To pass the CCS certification exam, candidates must achieve a scaled score of 300 or higher. This score reflects a sufficient level of competency in medical coding as determined by AHIMA's rigorous standards. Meeting this benchmark demonstrates a candidate's readiness to perform the duties of a certified coding specialist.

Question 12: What is the minimum education requirement to sit for the CCS exam?

Two years of work experience as a medical coder.
Completion of a physician’s assistant program.
Master’s degree in healthcare administration.
High school diploma or equivalent. (Correct answer)

Correct answer: High school diploma or equivalent.

While many candidates for the CCS exam have higher education or extensive experience, the minimum formal education requirement set by AHIMA to sit for the exam is a high school diploma or its equivalent. This allows individuals with practical experience or vocational training to pursue certification, recognizing diverse pathways to competency in medical coding.

Question 13: According to CPT coding guidelines, what is the definition of a 'new patient' for E/M office visits?

A patient who has changed insurance plans within the past year
A patient presenting for the first time to the current facility
A patient who has not received professional services from the physician or another physician of the same specialty in the same group practice within the past 3 years (Correct answer)
A patient who has never seen any physician in their life

Correct answer: A patient who has not received professional services from the physician or another physician of the same specialty in the same group practice within the past 3 years

CPT defines a new patient as one who has not received professional services from the physician, or another physician of the same exact specialty and subspecialty in the same group practice, within the past 3 years.

Question 14: Which of the following is the BEST indicator of high-quality outpatient E/M coding accuracy?

E/M level assignments consistently supported by documented medical decision making or time (Correct answer)
E/M levels uniform across all providers in the practice
All visits coded at the highest level to maximize reimbursement
E/M codes selected based on the number of diagnoses listed

Correct answer: E/M level assignments consistently supported by documented medical decision making or time

Per 2021 E/M guideline revisions, outpatient E/M level selection must be based on medical decision making (MDM) or total time, both of which must be documented to support the level billed.

Question 15: Which ICD-10-CM instruction tells the coder to assign an additional code when more information is needed to fully describe the condition?

Code also
Code first
Excludes1
Use additional code (Correct answer)

Correct answer: Use additional code

'Use additional code' instructs the coder to assign a supplementary code to provide complete information about the condition.

Question 16: ICD-10-CM Chapter 21 (Z codes) is primarily used to report:

Neoplasms and their morphology
Injuries and poisonings
Factors influencing health status and contact with health services (Correct answer)
Mental and behavioral disorders

Correct answer: Factors influencing health status and contact with health services

Z codes (Chapter 21) capture reasons for encounters other than disease or injury, such as screenings, vaccinations, or status conditions.

Question 17: A patient's claim is returned as 'unprocessable.' What is the most likely reason?

The claim was filed after the timely filing deadline
The procedure is not covered under the patient's plan
The patient owes a prior balance
Required fields such as subscriber ID or NPI are missing or invalid (Correct answer)

Correct answer: Required fields such as subscriber ID or NPI are missing or invalid

Unprocessable claims are returned (not denied) because they lack required data elements like a valid NPI, subscriber ID, or date of service, preventing the payer from adjudicating them.

Question 18: According to ICD-10-CM coding guidelines, how should a patient's chronic condition that is being managed during an inpatient admission be coded?

Code all chronic conditions that coexist at the time of admission and affect care (Correct answer)
Do not code chronic conditions; code only the principal diagnosis
Code only if the physician specifically states it affected the patient's care
Code chronic conditions only if they required specific treatment during the stay

Correct answer: Code all chronic conditions that coexist at the time of admission and affect care

ICD-10-CM Guidelines require coding of all conditions that coexist at the time of admission and affect patient care, treatment, or require monitoring during the encounter.

Question 19: What is the role of a code of ethics in the CCS profession?

To restrict professional freedom
To guide professional behavior and protect the public interest (Correct answer)
To create legal liability
To standardize pricing for services

Correct answer: To guide professional behavior and protect the public interest

A code of ethics establishes expectations for professional conduct and serves as a guide for ethical decision-making.

Question 20: Which data structure is used to implement Dijkstra's algorithm efficiently?

Priority queue (min-heap) (Correct answer)
Stack
Queue
Doubly linked list

Correct answer: Priority queue (min-heap)

A min-heap priority queue allows Dijkstra's algorithm to extract the minimum-distance unvisited node in O(log n).

Question 21: A surgeon performs a laparoscopic cholecystectomy and, during the same session, also performs a laparoscopic appendectomy for incidentally discovered appendicitis. How are these coded?

Only the cholecystectomy is coded - appendectomy is included
Only the more complex procedure is coded per CPT guidelines
Both procedures are coded, with Modifier -51 (Multiple Procedures) on the secondary procedure (Correct answer)
Both procedures are coded; no modifier needed since they are separate organ systems

Correct answer: Both procedures are coded, with Modifier -51 (Multiple Procedures) on the secondary procedure

When multiple distinct procedures are performed during the same session, CPT allows separate coding. Modifier -51 (Multiple Procedures) is appended to the secondary procedure to indicate it is an additional procedure subject to reimbursement reduction.

Question 22: What does the ICD-10-CM guideline state about coding 'probable' or 'suspected' diagnoses in the outpatient setting?

Query the physician to confirm before coding
Code both the probable diagnosis and the presenting symptom together
Code the probable diagnosis as if confirmed, same as inpatient
Do not code the probable diagnosis; code the signs, symptoms, or condition documented (Correct answer)

Correct answer: Do not code the probable diagnosis; code the signs, symptoms, or condition documented

In outpatient settings, ICD-10-CM Guidelines prohibit coding probable, suspected, or 'rule out' diagnoses. Code the documented sign, symptom, or finding instead.

Question 23: How many characters does every ICD-10-PCS code contain?

6
7 (Correct answer)
5
8

Correct answer: 7

All ICD-10-PCS codes are exactly 7 characters in length, with each character representing a specific axis of classification (section, body system, root operation, body part, approach, device, qualifier).

Question 24: 'Unbundling' in CPT coding refers to:

Splitting E/M services across multiple dates
Separately coding components of a procedure that should be reported with a single comprehensive code (Correct answer)
Using modifiers to reduce payment for a service
Combining multiple codes into one comprehensive code

Correct answer: Separately coding components of a procedure that should be reported with a single comprehensive code

Unbundling is the improper practice of billing multiple component codes separately when a single comprehensive CPT code exists to describe the complete service.

Question 25: When coding signs and symptoms in ICD-10-CM for an outpatient visit, the coder should:

Never code signs and symptoms if a chronic disease is also present
Code signs and symptoms when no definitive diagnosis has been established (Correct answer)
Code signs and symptoms only for inpatient encounters
Always code the suspected diagnosis instead of signs and symptoms

Correct answer: Code signs and symptoms when no definitive diagnosis has been established

For outpatient encounters, signs and symptoms are coded when the physician has not established a definitive diagnosis.

Question 26: A patient is admitted with pneumonia (MS-DRG 193, without CC/MCC) and is also found to have acute kidney injury. If the acute kidney injury qualifies as an MCC, the claim will be grouped to:

MS-DRG 193 - the MCC does not change simple pneumonia DRGs
MS-DRG 194 - Pneumonia with CC
MS-DRG 870 - the sepsis DRG, because AKI may indicate organ dysfunction
MS-DRG 191 - Pneumonia with MCC, higher relative weight (Correct answer)

Correct answer: MS-DRG 191 - Pneumonia with MCC, higher relative weight

Acute kidney injury is an MCC. With an MCC present, simple pneumonia groups to MS-DRG 191 (Respiratory Infections and Inflammations with MCC), which has a higher relative weight than the without CC/MCC variant.

Question 27: A pathology report confirming malignancy is received after the patient has been discharged. The attending physician documented 'suspected carcinoma' in the discharge summary. How should the diagnosis be coded?

Code the confirmed malignancy based on the pathology report (Correct answer)
Code only the signs and symptoms
Code the uncertain term 'suspected carcinoma'
Query the physician before coding either diagnosis

Correct answer: Code the confirmed malignancy based on the pathology report

Per ICD-10-CM guidelines, when a pathology report confirms a diagnosis after discharge, the confirmed diagnosis should be coded rather than the uncertain term.

Question 28: What is a collision in the context of hash tables?

Two values are identical
Two keys map to the same index (Correct answer)
A key is deleted while still referenced
The table exceeds its maximum size

Correct answer: Two keys map to the same index

A collision occurs when two different keys produce the same hash index, requiring a resolution strategy like chaining or open addressing.

Question 29: What is 'DRG creep' in the context of inpatient billing compliance?

The process of appealing incorrectly assigned low-weight DRGs
The systematic pattern of coding to higher-weighted DRGs without clinical documentation support (Correct answer)
The gradual annual increase in DRG relative weights due to inflation
The natural migration of cases to higher DRGs as patient populations become sicker

Correct answer: The systematic pattern of coding to higher-weighted DRGs without clinical documentation support

DRG creep refers to systematic upcoding - assigning codes that produce higher-paying DRGs than the clinical documentation supports - which is fraudulent and a major target of Medicare audits.

Question 30: What is the primary advantage of a trie (prefix tree) over a hash table for string lookups?

Tries have O(1) lookup regardless of string length
Tries require no collision handling
Tries use less memory for all datasets
Tries support prefix searches and ordered iteration efficiently (Correct answer)

Correct answer: Tries support prefix searches and ordered iteration efficiently

Tries allow efficient prefix queries and alphabetical iteration, which hash tables cannot natively support.

Question 31: What is the ICD-10-PCS root operation for the insertion of a urinary catheter for urine drainage?

Drainage (Correct answer)
Irrigation
Insertion
Dilation

Correct answer: Drainage

Insertion of a urinary catheter to drain urine uses root operation Drainage (value 9) - taking or letting out fluids and/or gases from a body part using a device.

Question 32: A patient has a pacemaker generator implanted in the subcutaneous tissue of the chest wall along with insertion of pacing leads into the right ventricle. How many ICD-10-PCS codes are needed?

Three codes - generator, right ventricular lead, and subcutaneous pocket
One code captures the entire procedure
One code with a combination device value
Two codes - one for the generator insertion and one for the lead insertion (Correct answer)

Correct answer: Two codes - one for the generator insertion and one for the lead insertion

ICD-10-PCS guidelines require separate codes for pacemaker generator insertion (into subcutaneous tissue) and lead insertion (into the cardiac chamber), as they involve different body parts.

Question 33: What is the purpose of a Remittance Advice (RA)?

To notify a patient of their financial responsibility
To explain how a claim was processed and what was paid or denied (Correct answer)
To authorize a procedure before it is performed
To request additional clinical documentation from the provider

Correct answer: To explain how a claim was processed and what was paid or denied

A Remittance Advice (RA) is sent by the payer to the provider detailing claim adjudication: amounts paid, contractual adjustments, and reason codes for denials.

Question 34: What is the purpose of the Medicare Code Editor (MCE) in the DRG grouping process?

To identify invalid codes, age conflicts, sex conflicts, and manifestation code errors before DRG assignment (Correct answer)
To assign the final DRG payment amount to each claim
To determine whether a diagnosis qualifies as a CC or MCC
To calculate the hospital's wage index adjustment

Correct answer: To identify invalid codes, age conflicts, sex conflicts, and manifestation code errors before DRG assignment

The Medicare Code Editor (MCE) is a software module that checks ICD-10-CM/PCS codes for validity and logical errors (age, sex conflicts, unacceptable principal diagnoses) before DRGs are assigned.

Question 35: Which of the following is included in the CCS exam structure?

Oral examination with healthcare professionals.
Multiple-choice and coding scenarios. (Correct answer)
Only theoretical questions on medical terminology.
Essay questions on healthcare policy.

Correct answer: Multiple-choice and coding scenarios.

The CCS exam structure includes a combination of multiple-choice questions that test theoretical knowledge and practical coding scenarios. These scenarios require candidates to apply coding guidelines to real-world medical documentation, demonstrating their ability to accurately assign codes. This comprehensive approach assesses both knowledge and practical application skills.

Question 36: What does the Health Insurance Portability and Accountability Act (HIPAA) transaction code set standard mandate for claims submission?

All claims must be submitted in paper format for Medicare
Only hospitals with more than 500 beds must submit electronic claims
Providers must use a single universal claim form for all payers
Electronic healthcare transactions must use HIPAA-mandated standard formats (X12 transactions) (Correct answer)

Correct answer: Electronic healthcare transactions must use HIPAA-mandated standard formats (X12 transactions)

HIPAA's administrative simplification provisions mandate that covered entities use X12 standard electronic transaction formats (e.g., 837P, 837I) for electronic claims submission.

Question 37: Under the Official Guidelines, what is the correct approach to coding a patient's HIV disease with an HIV-related condition?

Code Z21 (Asymptomatic HIV) with the related condition
Query the physician before coding any HIV-related diagnosis
Code only the HIV-related condition; HIV is implied
Sequence B20 (HIV disease) first, followed by codes for all HIV-related conditions (Correct answer)

Correct answer: Sequence B20 (HIV disease) first, followed by codes for all HIV-related conditions

ICD-10-CM Guidelines Section I.C.1.a state that B20 (HIV disease) is sequenced as principal/first-listed when the patient has confirmed HIV disease with associated conditions, followed by codes for all documented manifestations.

Question 38: CPT Category III codes (T-codes) are used for:

Codes that have been deleted from the CPT manual
Services requiring prior authorization
Temporary codes for emerging technology, services, and procedures to allow data collection (Correct answer)
Diagnostic tests only

Correct answer: Temporary codes for emerging technology, services, and procedures to allow data collection

Category III codes are temporary four-digit alphanumeric codes used to track utilization of new and emerging technologies and procedures.

Question 39: The MS-DRG system includes Complication or Comorbidity (CC) and Major Complication or Comorbidity (MCC) designations. What is their primary purpose?

To increase DRG payment weight when documented conditions affect resource use (Correct answer)
To flag claims for Medicare audit review
To determine the patient's readmission risk score
To identify hospital-acquired conditions for quality reporting

Correct answer: To increase DRG payment weight when documented conditions affect resource use

CCs and MCCs are secondary diagnoses that, when present and documented, move the DRG to a higher-paying variant, reflecting increased patient complexity and resource consumption.

Question 40: Under the ICD-10-CM Official Guidelines, the term 'code also' means:

An additional code should be reported if applicable and present (Correct answer)
An additional code is required to fully describe the condition
The code following should always be sequenced first
Only one code may be assigned for this condition

Correct answer: An additional code should be reported if applicable and present

'Code also' is an instructional note indicating that an additional code may be assigned if the condition is present and applicable - it is not always mandatory.

Question 41: According to ICD-10-CM guidelines for sepsis, which of the following sequences is correct when a patient is admitted with sepsis due to MRSA pneumonia?

A41.02 (Sepsis due to MRSA) sequenced first, then J15.212 (Pneumonia due to MRSA) (Correct answer)
J18.9 (Pneumonia, unspecified) sequenced first, then A41.02 (Sepsis due to MRSA)
B95.62 (MRSA) sequenced first, then A41.02
Sepsis cannot be coded with pneumonia on the same claim

Correct answer: A41.02 (Sepsis due to MRSA) sequenced first, then J15.212 (Pneumonia due to MRSA)

When sepsis is present on admission with a localized infection, the sepsis is sequenced as principal diagnosis, followed by the specific infection (MRSA pneumonia).

Question 42: What is the purpose of CPT modifier -25?

Indicates a significant, separately identifiable E/M service was performed by the same physician on the same day as a procedure (Correct answer)
Indicates a reduced service was performed
Indicates the procedure was performed by a different provider
Indicates a bilateral procedure

Correct answer: Indicates a significant, separately identifiable E/M service was performed by the same physician on the same day as a procedure

Modifier -25 is appended to an E/M code to indicate that a separate, significant E/M service was provided on the same day as a procedure or service.

Question 43: Which act prohibits surprise billing for emergency services from out-of-network providers at in-network facilities?

The No Surprises Act (Correct answer)
The Stark Law
ERISA
HIPAA

Correct answer: The No Surprises Act

The No Surprises Act (effective January 1, 2022) protects patients from unexpected bills for emergency care and certain non-emergency services from out-of-network providers at in-network facilities.

Question 44: Which government program provides healthcare coverage for individuals aged 65 and older?

Medicare (Correct answer)
TRICARE
Affordable Care Act (ACA)
Medicaid

Correct answer: Medicare

Medicare is the federal government program that provides healthcare coverage primarily for individuals aged 65 and older. It also covers certain younger people with disabilities and those with End-Stage Renal Disease. Medicare helps cover hospital stays, doctor visits, and prescription drugs, playing a crucial role in the U.S. healthcare system.

Question 45: What is the purpose of the HCPCS Level II code set?

To code for physician services only when CPT codes are not available
To describe ICD-10-CM diagnoses in outpatient billing
To replace CPT codes for all Medicare billing
To supplement CPT codes for services, supplies, and equipment not described in CPT (Correct answer)

Correct answer: To supplement CPT codes for services, supplies, and equipment not described in CPT

HCPCS Level II codes (A0000-V9999) supplement CPT codes by describing non-physician services, supplies, equipment, drugs, and other items that CPT does not adequately represent.

Question 46: In the context of clinical documentation improvement (CDI), which type of query format asks the physician to choose from a list of clinically supported options?

Multiple choice query (Correct answer)
Retrospective query
Yes/No query
Open-ended query

Correct answer: Multiple choice query

A multiple choice query presents the physician with clinically supported diagnostic options to choose from, along with space to add an unlisted response, making it compliant and efficient.

Question 47: What does the acronym CRUD stand for in the context of database operations?

Configure, Record, Upload, Distribute
Compile, Run, Update, Delete
Copy, Retrieve, Undo, Deploy
Create, Read, Update, Delete (Correct answer)

Correct answer: Create, Read, Update, Delete

CRUD represents the four basic database operations: Create, Read, Update, and Delete, which cover all fundamental data manipulation tasks.

Question 48: In ICD-10-PCS, what does the root operation 'Excision' mean?

Removing a foreign body from a body part
Cutting out or off all of a body part
Separating or transecting a body part
Cutting out or off a portion of a body part without replacement (Correct answer)

Correct answer: Cutting out or off a portion of a body part without replacement

ICD-10-PCS defines 'Excision' as cutting out or off, without replacement, a portion of a body part - distinguishing it from 'Resection' (all of a body part).

Question 49: How long is the CCS certification valid before requiring renewal?

One year
It does not expire
Two years (Correct answer)
Five years

Correct answer: Two years

The CCS certification is valid for a period of two years. To maintain the certification, professionals must complete continuing education units (CEUs) and adhere to AHIMA's recertification requirements within this two-year cycle. This ensures that certified coders stay current with evolving coding guidelines and industry changes.

Question 50: A health information manager discovers that 200 records have been accessed by an employee without a treatment, payment, or operations purpose. Under HIPAA, this constitutes:

A breach requiring assessment under the Breach Notification Rule (Correct answer)
A routine audit finding with no required action
A minor policy violation requiring retraining only
A HIPAA violation only if the records were shared externally

Correct answer: A breach requiring assessment under the Breach Notification Rule

Unauthorized access to PHI is a potential breach under HIPAA. The covered entity must conduct a breach risk assessment and may be required to notify affected individuals and HHS.

Question 51: What is the primary purpose of ICD-10-CM coding?

To identify hospital room numbers.
To classify diseases and conditions. (Correct answer)
To determine insurance premiums.
To describe surgical procedures.

Correct answer: To classify diseases and conditions.

The primary purpose of ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) coding is to classify diseases, injuries, symptoms, and other health conditions. This standardized system provides a universal language for reporting diagnoses, which is essential for accurate medical billing, tracking public health statistics, and conducting epidemiological research.

Question 52: In graph theory, what is a topological sort used for?

Ordering nodes in a directed acyclic graph so all edges point forward (Correct answer)
Detecting cycles in an undirected graph
Balancing a binary search tree
Finding the shortest path between two nodes

Correct answer: Ordering nodes in a directed acyclic graph so all edges point forward

Topological sort linearly orders DAG vertices such that for every directed edge u→v, u appears before v.

Question 53: Which type of insurance plan requires patients to choose a primary care provider (PCP)?

Catastrophic health plan
Health Maintenance Organization (HMO) (Correct answer)
Preferred Provider Organization (PPO)
Fee-for-service plan

Correct answer: Health Maintenance Organization (HMO)

Health Maintenance Organizations (HMOs) are characterized by their managed care approach, which typically requires members to select a primary care provider (PCP) from a network. This PCP acts as a gatekeeper, coordinating all healthcare services and providing referrals for specialist visits. This structure helps manage costs and ensures integrated care within the plan's network.

Question 54: HCPCS Level II codes are used primarily to report:

Inpatient hospital procedures
Medical supplies, durable medical equipment, drugs, and services not covered by CPT (Correct answer)
Physician services coded in CPT
ICD-10-PCS procedure codes

Correct answer: Medical supplies, durable medical equipment, drugs, and services not covered by CPT

HCPCS Level II codes cover supplies, equipment, drugs, ambulance services, and other items not captured by CPT codes.

Question 55: What is the primary purpose of the electronic health record (EHR) audit trail in the context of medical coding compliance?

To record who accessed or modified patient records and when (Correct answer)
To track the number of codes assigned per encounter
To calculate reimbursement amounts for each encounter
To automatically assign ICD-10 codes based on documentation

Correct answer: To record who accessed or modified patient records and when

The EHR audit trail creates a chronological log of who accessed, modified, or viewed patient records, which is essential for compliance, security, and legal purposes.

Question 56: Which document created during SDLC analysis describes the boundaries of a health IT project?

System architecture diagram
Data flow diagram
Scope statement (Correct answer)
Test plan

Correct answer: Scope statement

A scope statement defines what is included in and excluded from the project to prevent scope creep.

Question 57: Which coding system is primarily used for outpatient procedures?

ICD-10-CM
CPT (Correct answer)
HCPCS Level II
DRG

Correct answer: CPT

CPT (Current Procedural Terminology) is the coding system primarily used for reporting outpatient medical, surgical, and diagnostic procedures and services. These codes are essential for healthcare providers to accurately describe the services rendered to patients for billing and reimbursement purposes, particularly in physician offices and outpatient clinics.

Question 58: A candidate fails the CCS exam. What is the minimum waiting period before retaking it?

6 months after the failed attempt
90 days after the failed attempt (Correct answer)
1 year after the failed attempt
No waiting period - can retake immediately

Correct answer: 90 days after the failed attempt

AHIMA requires a minimum of 90 days between CCS exam attempts to allow candidates time to study and improve before retesting.

Question 59: Which federal regulation establishes the legal requirement for maintaining the confidentiality and security of patient health information in the United States?

False Claims Act
HIPAA (Correct answer)
STARK Law
EMTALA

Correct answer: HIPAA

HIPAA (Health Insurance Portability and Accountability Act) establishes national standards for the protection of individually identifiable health information and governs its use and disclosure.

Question 60: Which ICD-10-PCS root operation describes 'putting in a nonbiological device that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part'?

Replacement
Supplement
Insertion (Correct answer)
Fusion

Correct answer: Insertion

ICD-10-PCS defines root operation Insertion (H) as putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function - such as pacemakers, monitoring devices, or ports.

Question 62: Which graph representation is most space-efficient for a sparse graph?

Edge list stored in a 2D array
Adjacency list (Correct answer)
Adjacency matrix
Incidence matrix

Correct answer: Adjacency list

An adjacency list uses space proportional to the number of edges, which is efficient for sparse graphs.

Question 63: CPT Category II codes are used for:

Telemedicine services only
Inpatient-only procedures requiring a hospital setting
New or experimental technology not yet assigned a Category I code
Supplemental tracking codes for performance measurement that are optional and do not affect reimbursement (Correct answer)

Correct answer: Supplemental tracking codes for performance measurement that are optional and do not affect reimbursement

Question 64: Which organization is responsible for maintaining and updating the ICD-10-CM code set in the United States?

American Hospital Association (AHA)
National Center for Health Statistics (NCHS) and CMS, as cooperating parties (Correct answer)
American Medical Association (AMA)
AHIMA exclusively

Correct answer: National Center for Health Statistics (NCHS) and CMS, as cooperating parties

ICD-10-CM is maintained by NCHS (National Center for Health Statistics), a division of CDC, in cooperation with CMS. Updates are effective each October 1.

Question 65: How does accurate data entry benefit healthcare organizations?

It improves patient care and efficiency. (Correct answer)
It removes the need for compliance audits.
It slows down the billing process.
It increases administrative costs.

Correct answer: It improves patient care and efficiency.

Accurate data entry significantly benefits healthcare organizations by improving patient care and operational efficiency. Precise information leads to correct diagnoses, appropriate treatments, and seamless communication among care providers, reducing medical errors. It also streamlines administrative processes, leading to more efficient billing and resource allocation.

Question 66: A health plan removes a provider from its network. What is this action called?

Disenrollment
De-credentialing (Correct answer)
Network exclusion
Provider suspension

Correct answer: De-credentialing

De-credentialing is the formal process of removing a provider from a health plan's network, often due to quality concerns, license issues, or failure to meet standards.

Question 67: The surgical package in CPT includes all of the following EXCEPT:

Writing orders and evaluating the patient the day before or day of surgery
Post-operative pain management beyond the global period requiring a return visit (Correct answer)
Immediate post-operative care in the recovery area
Local infiltration and topical anesthesia

Correct answer: Post-operative pain management beyond the global period requiring a return visit

Services required beyond the global period due to complications or new conditions are separately billable and are not included in the surgical package.

Question 68: What coding resources are candidates permitted to use during the CCS exam?

No references allowed - all from memory
Electronic versions of ICD-10-CM, ICD-10-PCS, and CPT code books built into the exam (Correct answer)
Personal printed code books brought by the candidate
Internet access to CMS coding guidelines

Correct answer: Electronic versions of ICD-10-CM, ICD-10-PCS, and CPT code books built into the exam

The CCS exam is an open-book exam: AHIMA provides electronic versions of ICD-10-CM, ICD-10-PCS, and CPT code sets within the testing software - candidates do not bring personal books.

Question 69: Which tree property guarantees O(log n) height for balanced binary search trees?

The root always holds the median value
The height difference between left and right subtrees is at most 1 (Correct answer)
All leaf nodes are at the same depth
Each node has exactly two children

Correct answer: The height difference between left and right subtrees is at most 1

AVL trees enforce that the height difference (balance factor) between subtrees is at most 1, keeping height at O(log n).

Question 70: A coder is reviewing a record where the physician documented 'dehydration due to nausea and vomiting secondary to chemotherapy.' Which condition should be sequenced as the principal diagnosis for an inpatient admission?

Dehydration (Correct answer)
The underlying malignancy being treated with chemotherapy
Nausea and vomiting
Adverse effect of chemotherapy

Correct answer: Dehydration

Dehydration is the condition established after study to be chiefly responsible for occasioning the admission; the nausea/vomiting and chemotherapy context are coded as additional diagnoses.

Question 71: What does amortized O(1) mean for dynamic array append operations?

Each append is guaranteed to take constant time
Append is O(1) on average over many operations despite occasional O(n) resizing (Correct answer)
The array never needs to be resized
Appending is only fast for the first n elements

Correct answer: Append is O(1) on average over many operations despite occasional O(n) resizing

Although resizing costs O(n), it happens infrequently enough that the average cost per append is O(1) amortized.

Question 72: Under the HIPAA Minimum Necessary Rule, which scenario is most appropriate?

A receptionist views all lab results to verify patient identity
A biller accesses only the claim-related diagnosis and procedure codes needed for billing (Correct answer)
A coder accesses the full psychiatric notes to code a routine fracture repair
A physician reviews all records for every patient in the practice daily

Correct answer: A biller accesses only the claim-related diagnosis and procedure codes needed for billing

The minimum necessary standard requires that access to PHI be limited to the specific information required to complete the task at hand.

Question 73: Which CPT code range covers Evaluation and Management services for Emergency Department visits?

99241-99245
99202-99215
99221-99223
99281-99285 (Correct answer)

Correct answer: 99281-99285

CPT codes 99281-99285 are the Emergency Department E/M codes, assigned by the facility and physician based on the medical decision making and presenting problem severity.

Question 74: In ICD-10-CM, when coding drug-induced conditions, the coder must:

Code only the drug code from T36-T50
Code only the condition caused by the drug
Code the condition first, then use an additional code from T36-T50 to identify the drug (Correct answer)
Query the physician before assigning any drug-related code

Correct answer: Code the condition first, then use an additional code from T36-T50 to identify the drug

Drug-induced conditions require coding the manifestation first followed by a T-code from T36-T50 identifying the causative drug.

Question 75: What is the consequence of upcoding in medical coding?

Legal and financial penalties. (Correct answer)
Increased provider reimbursement without issue.
Improved patient satisfaction.
Faster claims processing.

Correct answer: Legal and financial penalties.

Upcoding involves intentionally billing for a more expensive service or procedure than what was actually performed or documented. This fraudulent practice can lead to significant legal and financial penalties for healthcare providers, including fines, audits, and exclusion from federal healthcare programs. It undermines the integrity of the billing system and can result in overpayment by insurers.

Question 76: Which federal law prohibits offering, paying, soliciting, or receiving anything of value to induce or reward referrals of federal health care program business?

Stark Law
False Claims Act
HIPAA
Anti-Kickback Statute (AKS) (Correct answer)

Correct answer: Anti-Kickback Statute (AKS)

The Anti-Kickback Statute (AKS) makes it a criminal offense to knowingly offer remuneration to induce referrals for services covered by federal health programs.

Question 77: Which database field type is most appropriate for storing a patient's date of birth in a healthcare information system?

DATE (Correct answer)
INTEGER
VARCHAR
BOOLEAN

Correct answer: DATE

Question 78: A patient undergoes an open reduction and internal fixation (ORIF) of a displaced femoral shaft fracture. What is the ICD-10-PCS root operation?

Reposition (Correct answer)
Replacement
Fusion
Repair

Correct answer: Reposition

ORIF is classified as 'Reposition' in ICD-10-PCS - moving a body part to its normal or other suitable location - with an internal fixation device applied.

Question 79: Which organization administers and owns the CCS credential?

Centers for Medicare & Medicaid Services (CMS)
American Academy of Professional Coders (AAPC)
American Health Information Management Association (AHIMA) (Correct answer)
American Medical Association (AMA)

Correct answer: American Health Information Management Association (AHIMA)

The CCS credential is owned and administered by AHIMA (American Health Information Management Association), the professional association for health information management professionals.

Question 80: A coder is reviewing a claim for a patient admitted with alcohol-induced acute pancreatitis with documented dehydration. Which coding approach maximizes compliant reimbursement?

Code only the dehydration since it was the actively treated condition
Code E86.0 as the principal diagnosis since it required IV fluid treatment
Code only K85.20 (Alcohol-induced acute pancreatitis without necrosis or infection)
Code K85.20 for the pancreatitis and E86.0 (Dehydration) as a secondary diagnosis, which may qualify as a CC (Correct answer)

Correct answer: Code K85.20 for the pancreatitis and E86.0 (Dehydration) as a secondary diagnosis, which may qualify as a CC

The correct approach codes the principal diagnosis (acute pancreatitis K85.20) with dehydration (E86.0) as a secondary diagnosis. Dehydration qualifies as a CC for many DRGs, accurately capturing patient complexity and improving DRG assignment.

Question 81: The three key components used to select an E/M (Evaluation and Management) level of service are:

Diagnosis, treatment plan, and follow-up interval
Chief complaint, past history, and review of systems
Time, diagnosis, and procedure performed
History, examination, and medical decision making (Correct answer)

Correct answer: History, examination, and medical decision making

E/M code selection is based on the level of history obtained, the extent of physical examination performed, and the complexity of medical decision making.

Question 82: Which AHIMA content domain on the CCS exam has the highest percentage of test questions?

Compliance and data quality
ICD-10-CM and ICD-10-PCS coding (Correct answer)
CPT/HCPCS coding
Health information documentation

Correct answer: ICD-10-CM and ICD-10-PCS coding

ICD-10-CM and ICD-10-PCS coding represents the largest single content domain on the CCS exam, reflecting the core coding competency required of hospital-based coders.

Question 83: Which of the following best describes 'upcoding' in the context of medical record documentation and coding compliance?

Updating codes annually to reflect ICD-10-CM guideline changes
Assigning codes that result in higher reimbursement than the documented services support (Correct answer)
Using combination codes instead of multiple codes to describe a condition
Assigning codes to the highest level of specificity available

Correct answer: Assigning codes that result in higher reimbursement than the documented services support

Upcoding is a fraudulent practice of assigning codes that generate higher reimbursement than is warranted by the actual documented and rendered services, which violates the False Claims Act.

Question 84: What is the function of the Hospital Compare database maintained by CMS?

To track all hospital coding errors for OIG investigations
To manage Medicare credentialing for hospital physicians
To rank hospitals by financial performance and revenue cycle metrics
To publicly report quality measures allowing consumers to compare hospital performance (Correct answer)

Hospital Compare (now Care Compare) is a CMS consumer tool that publicly reports hospital quality measures including mortality rates, readmissions, patient experience (HCAHPS), and process measures.

Question 85: The CCS exam uses which type of questions exclusively?

Essay and case study analysis
Multiple-choice only
True/false and fill-in-the-blank
Multiple-choice and medical record coding simulations (Correct answer)

Correct answer: Multiple-choice and medical record coding simulations

The CCS exam includes multiple-choice questions AND medical record simulation sections where candidates must assign codes from actual (simulated) medical records.

Question 86: What is the correct sequencing when coding a condition with both an acute and chronic presentation in ICD-10-CM?

Code only the acute condition
Code only the chronic condition
Code the acute condition first, followed by the chronic condition (Correct answer)
Code the chronic condition first, followed by the acute condition

Correct answer: Code the acute condition first, followed by the chronic condition

When both acute and chronic forms of the same condition exist, the acute (subacute) code is sequenced first.

Question 87: What is the purpose of medical coding in the billing process?

To increase insurance premiums.
To determine physician salaries.
To eliminate medical documentation.
To ensure proper billing and reimbursement. (Correct answer)

Correct answer: To ensure proper billing and reimbursement.

The purpose of medical coding in the billing process is to translate healthcare services, diagnoses, and procedures into standardized alphanumeric codes. These codes are essential for submitting accurate claims to insurance companies, which then use them to determine appropriate reimbursement for providers. Proper coding ensures efficient processing and prevents claim denials.

Question 88: The 'separate procedure' designation in CPT means:

The procedure requires its own operative report
The procedure is always reported separately regardless of other services
The procedure must be performed by a different surgeon
The procedure is commonly carried out as part of a larger service and should not be reported separately when performed as an integral component (Correct answer)

Correct answer: The procedure is commonly carried out as part of a larger service and should not be reported separately when performed as an integral component

A 'separate procedure' designation means the code should only be reported independently when it is not incidental to another more complex procedure performed at the same session.

Question 89: Which document in the health record serves as the primary source for assigning the principal diagnosis in an inpatient stay?

Physician's discharge summary (Correct answer)
Emergency department report
Nursing admission assessment
Radiology interpretation

Correct answer: Physician's discharge summary

The physician's discharge summary provides a comprehensive account of the entire hospital stay and is the primary source for principal diagnosis assignment.

Question 90: In ICD-10-PCS, what is the approach value for a procedure performed entirely through a natural body orifice using an endoscope (e.g., colonoscopy)?

8 - Via Natural or Artificial Opening Endoscopic (Correct answer)
3 - Percutaneous
F - Via Natural or Artificial Opening With Percutaneous Endoscopic Assistance
7 - Via Natural or Artificial Opening

Correct answer: 8 - Via Natural or Artificial Opening Endoscopic

Approach 8 (Via Natural or Artificial Opening Endoscopic) is used for endoscopic procedures performed through a natural orifice using an endoscope - such as colonoscopy, upper GI endoscopy, or cystoscopy.

Question 91: In ICD-10-CM, what is the 'default code' concept?

The first code in a code range used for billing
A code that covers all unspecified conditions in a chapter
A code automatically applied when no documentation exists
The code listed next to a main term in the Index when no additional detail or subterm is provided (Correct answer)

Correct answer: The code listed next to a main term in the Index when no additional detail or subterm is provided

The default code is the code listed next to a main term in the Alphabetic Index and is used when documentation does not specify additional detail.

Question 92: Which ICD-10-CM instruction requires the underlying condition to be coded first, followed by the manifestation?

Code also
Use additional code
Code first (Correct answer)
Excludes2

Correct answer: Code first

A 'Code first' note instructs the coder to sequence the underlying etiology before the manifestation code.

Question 93: What is the National Correct Coding Initiative (NCCI) and its relevance to outpatient hospital coding?

A CMS program that assigns APC status indicators to CPT codes
A CMS initiative that establishes code pair edits preventing inappropriate billing of CPT code combinations that should be bundled (Correct answer)
A quality reporting program that tracks outpatient coding accuracy rates
An AHIMA certification program for outpatient coding specialists

Correct answer: A CMS initiative that establishes code pair edits preventing inappropriate billing of CPT code combinations that should be bundled

NCCI (CCI) contains tables of CPT code pairs that cannot be billed together by the same provider on the same day - one is the 'comprehensive' code, the other is the 'component,' and billing both is considered unbundling.

Question 94: Which Medicare quality program penalizes hospitals with excessive 30-day readmission rates for specific conditions by reducing IPPS payments?

Hospital Readmissions Reduction Program (HRRP) (Correct answer)
Merit-Based Incentive Payment System (MIPS)
Value-Based Purchasing (VBP) Program
Hospital-Acquired Condition (HAC) Reduction Program

Correct answer: Hospital Readmissions Reduction Program (HRRP)

The Hospital Readmissions Reduction Program (HRRP) reduces Medicare IPPS payments to hospitals with excess readmission rates for specified conditions including AMI, heart failure, pneumonia, COPD, CABG, and joint replacement.

Question 95: What is the purpose of a queue data structure?

To sort elements automatically
To process elements in First-In-First-Out (FIFO) order (Correct answer)
To enable random access to elements
To store elements in sorted order

Correct answer: To process elements in First-In-First-Out (FIFO) order

Queues process elements in FIFO order, like a line at a store — first to arrive is first to be served.

Question 96: Which health record document would a coder primarily reference to assign CPT codes for surgical procedures performed in the operating room?

Recovery room notes
Pre-operative nursing checklist
Anesthesia record
Operative report (Correct answer)

Correct answer: Operative report

The operative report, dictated by the surgeon, describes the procedure performed in detail and is the primary source for assigning surgical CPT procedure codes.

Question 97: Which data quality characteristic ensures that health information is available when needed by authorized users?

Timeliness
Completeness
Accessibility (Correct answer)
Accuracy

Correct answer: Accessibility

Accessibility refers to data being available and retrievable by authorized users when needed - a core characteristic of high-quality health information.

Question 98: HCPCS Level I codes are:

Numeric codes identical to CPT codes, maintained by the AMA (Correct answer)
Codes for temporary procedures pending FDA approval
Alphanumeric codes for supplies and equipment created by CMS
Codes used exclusively for Medicare claims

Correct answer: Numeric codes identical to CPT codes, maintained by the AMA

HCPCS Level I consists of the CPT code set (numeric codes) maintained by the AMA and adopted for use in the HCPCS system.

Question 99: When a patient's record indicates a condition was 'ruled out' during the inpatient stay, how should this be coded for inpatient purposes?

Leave the condition uncoded since it was excluded
Code both the condition and the signs and symptoms
Code the signs and symptoms that prompted the workup (Correct answer)
Code the condition that was ruled out as if confirmed

Correct answer: Code the signs and symptoms that prompted the workup

When a condition is ruled out during an inpatient stay, coders should report the signs and symptoms that led to the investigation, not the condition that was excluded.

Question 100: A hospital is reviewed by a Recovery Audit Contractor (RAC). What type of claims does the RAC primarily target?

Improper Medicare fee-for-service payments including coding errors, billing errors, and non-covered services (Correct answer)
Medicaid claims for nursing home services exclusively
All Medicare Advantage claims regardless of amount
Only claims submitted more than 3 years ago

Correct answer: Improper Medicare fee-for-service payments including coding errors, billing errors, and non-covered services

RACs (Recovery Audit Contractors) identify and recover improper Medicare fee-for-service payments, including overpayments from upcoding, duplicate billing, and non-covered services, as well as underpayments.

Question 101: On the CCS exam, medical record simulations primarily test a candidate's ability to:

Identify billing errors and calculate claim totals
Accurately assign and sequence ICD-10-CM, ICD-10-PCS, and/or CPT codes from clinical documentation (Correct answer)
Complete the UB-04 form with all required fields
Interpret laboratory values and vital signs

Correct answer: Accurately assign and sequence ICD-10-CM, ICD-10-PCS, and/or CPT codes from clinical documentation

The medical record simulations on the CCS exam require candidates to read clinical documentation and correctly assign and sequence codes - the fundamental skill of a hospital coder.

Question 102: The 'principal diagnosis' for an inpatient encounter is defined as:

The most resource-intensive condition treated
The condition established after study to be chiefly responsible for occasioning the admission (Correct answer)
The diagnosis present on admission
The first diagnosis listed in the medical record

Correct answer: The condition established after study to be chiefly responsible for occasioning the admission

The principal diagnosis is determined after workup and defined as the condition chiefly responsible for the patient's admission to the hospital.

Question 103: What is the purpose of a claim denial appeal in medical billing?

To request higher payment rates.
To eliminate the need for patient billing.
To contest an insurance claim denial. (Correct answer)
To reduce insurance processing times.

Correct answer: To contest an insurance claim denial.

The purpose of a claim denial appeal in medical billing is to formally contest an insurance company's decision to deny payment for a healthcare service. When a claim is denied, providers or patients can submit an appeal with additional documentation or clarification to argue for the medical necessity or appropriateness of the service. The goal is to overturn the denial and secure reimbursement.

Question 104: What is the purpose of a clinical documentation improvement (CDI) program in a hospital?

To reduce the number of physician queries by limiting coder access to records
To convert paper records to electronic format
To improve the accuracy and completeness of clinical documentation to support coding, reimbursement, and quality reporting (Correct answer)
To train coders on new CPT codes each year

Correct answer: To improve the accuracy and completeness of clinical documentation to support coding, reimbursement, and quality reporting

CDI programs proactively review and improve clinical documentation to ensure it accurately reflects patient severity, supports correct code assignment, and accurately represents quality outcomes.

Question 105: The 'global surgical package' concept in CPT means:

Only the surgeon's fee is included in the package
All procedures are bundled into one payment regardless of complexity
Global billing requires use of a modifier on all surgical codes
The surgical fee includes pre-operative, intra-operative, and post-operative services for a defined period (Correct answer)

Correct answer: The surgical fee includes pre-operative, intra-operative, and post-operative services for a defined period

The global surgical package bundles the surgeon's pre-op evaluation, the procedure itself, and post-op care within the defined global period into one fee.

Question 106: What does an 'Excludes1' note in ICD-10-CM mean?

The excluded code should always be sequenced first
The condition is included in the default code
The excluded code may be used together with this code
The two conditions cannot occur together and cannot be coded simultaneously (Correct answer)

Correct answer: The two conditions cannot occur together and cannot be coded simultaneously

An Excludes1 note means the two conditions are mutually exclusive and cannot be reported together on the same claim.

Question 107: In ICD-10-PCS, what is the root operation for a coronary artery bypass graft (CABG) procedure?

Bypass (Correct answer)
Repair
Transfer
Replacement

Correct answer: Bypass

CABG is classified using the ICD-10-PCS root operation 'Bypass' (value 1), which means altering the route of passage of the contents of a tubular body part.
