CDIP CPT and HCPCS Code Assignment — Questions and Answers
Question 1: What does CPT stand for in the context of medical procedure coding?
- Clinical Protocol Terminology
- Current Procedural Terminology (Correct answer)
- Certified Physician Taxonomy
- Comprehensive Procedural Terminology
Correct answer: Current Procedural Terminology
CPT stands for Current Procedural Terminology. It is a code set maintained by the American Medical Association (AMA) used to report medical, surgical, and diagnostic procedures and services, primarily in outpatient and physician settings.
Question 2: HCPCS Level II codes are alphanumeric codes maintained by CMS primarily used to report which of the following?
- Inpatient diagnoses and hospital complications
- MS-DRG weights and reimbursement categories
- Durable medical equipment, prosthetics, orthotics, supplies, and services not found in CPT (Correct answer)
- Surgical procedures performed in the operating room
Correct answer: Durable medical equipment, prosthetics, orthotics, supplies, and services not found in CPT
HCPCS Level II codes (e.g., A-codes for supplies, E-codes for DME, J-codes for injectable drugs) are CMS-maintained alphanumeric codes that cover items and services not represented in CPT, most commonly durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS).
Question 3: In the outpatient hospital facility setting, CPT codes drive reimbursement under which Medicare payment system?
- Inpatient Prospective Payment System (IPPS)
- All Patient Refined DRGs (APR-DRGs)
- Resource-Based Relative Value Scale (RBRVS)
- Ambulatory Payment Classifications (APCs) (Correct answer)
Correct answer: Ambulatory Payment Classifications (APCs)
Outpatient hospital services billed by facilities to Medicare are reimbursed through the Outpatient Prospective Payment System (OPPS), which groups services into Ambulatory Payment Classifications (APCs) based on CPT codes. RBRVS is used for physician professional fees, not facility payments.
Question 4: An operative report documents 'excision of a 2.3 cm benign lesion of the back,' but the coder assigned a CPT code for destruction of the lesion. What is the most appropriate action for the CDI specialist?
- Correct the code directly in the EHR coding module
- Contact the surgeon to amend the operative report language to match the code
- Communicate with the coding/HIM staff to review the documentation and resolve the discrepancy (Correct answer)
- Submit the claim as coded since excision and destruction are clinically equivalent
Correct answer: Communicate with the coding/HIM staff to review the documentation and resolve the discrepancy
Excision (removal with margins) and destruction (ablation of tissue) are distinct CPT procedures with different codes and reimbursement levels. The CDI specialist's role is to facilitate resolution by communicating with coding/HIM staff — not to change codes unilaterally or alter physician documentation to match an incorrect code.
Question 5: A physician documents 'intravenous infusion of therapeutic drug' without specifying the drug name or infusion duration. Why does this documentation gap matter for CPT coding?
- CPT infusion codes do not require drug specificity — the route of administration is sufficient
- CPT infusion codes require the drug identity and total infusion time to select the correct code, making a query to the physician appropriate (Correct answer)
- Infusion documentation is exclusively the nurse's responsibility and cannot be queried
- Drug specificity only matters for ICD-10-CM adverse effect coding, not CPT
Correct answer: CPT infusion codes require the drug identity and total infusion time to select the correct code, making a query to the physician appropriate
CPT infusion codes (e.g., 96365–96368 for therapeutic infusions) are selected based on the drug administered and the duration of infusion. Without this information, the correct code cannot be determined. A compliant, non-leading query to the physician or nursing staff to clarify these details is appropriate.
Question 6: Which of the following statements correctly distinguishes CPT Category I codes from Category III codes?
- Category I codes are for emerging technologies only; Category III codes are for established high-volume procedures
- Category III codes are temporary, five-digit T-codes for new and emerging technologies and services that may lack sufficient data for permanent Category I status (Correct answer)
- Category III codes are maintained by CMS, while Category I codes are maintained by the AMA
- Category I and Category III codes are interchangeable for outpatient facility billing
Correct answer: Category III codes are temporary, five-digit T-codes for new and emerging technologies and services that may lack sufficient data for permanent Category I status
CPT Category III codes are temporary tracking codes (formatted as four digits plus the letter T) used for emerging technologies, services, and procedures. They allow data collection that may support eventual promotion to permanent Category I status. Category I codes represent established procedures with documented clinical efficacy and significant utilization.
