AAPC - American Academy of Professional Coders HCPCS Level II and Compliance Questions and Answers — Questions and Answers
Question 1: A physician's office administers a 75 mg injection of a specific drug. The HCPCS Level II code for this drug is defined in the manual as "Injection, DrugX, 25 mg". How should this service be reported to ensure compliance and accurate billing?
- Report the J-code with modifier -52 (Reduced Services).
- Report the J-code on three separate lines of the claim, each with one unit.
- Report the J-code with three units of service in the units field of the claim. (Correct answer)
- Report the J-code with one unit of service and triple the charge for the drug.
Correct answer: Report the J-code with three units of service in the units field of the claim.
To bill HCPCS Level II drug codes accurately, the total dosage administered must be converted into the number of billable units defined by the code descriptor. In this case, 75 mg was administered, and the code's unit is 25 mg. Therefore, 75 mg / 25 mg = 3 units. This is reported on a single claim line with the appropriate J-code and "3" entered in the units field.
Question 2: What is the primary purpose of the HCPCS Level II code set?
- To classify diseases and health problems for statistical purposes.
- To provide a standardized coding system for physician and other healthcare professional services.
- To report inpatient hospital procedures for Diagnosis-Related Group (DRG) assignment.
- To identify products, supplies, and services not included in the CPT code set, such as ambulance services and DME. (Correct answer)
Correct answer: To identify products, supplies, and services not included in the CPT code set, such as ambulance services and DME.
The Healthcare Common Procedure Coding System (HCPCS) is divided into two levels. Level I is the CPT code set. Level II is used to report products, supplies, and services that are not found in CPT. This includes durable medical equipment (DME), prosthetics, orthotics, supplies (DMEPOS), ambulance services, and specific drugs.
Question 3: An Advance Beneficiary Notice of Noncoverage (ABN) must be obtained from a Medicare beneficiary in which of the following situations?
- After a service has been provided and a denial has been received from Medicare.
- Before providing a service that is statutorily excluded from Medicare, such as cosmetic surgery.
- When a provider believes a typically covered service may not be considered medically necessary by Medicare for a specific patient. (Correct answer)
- For all services provided to Medicare beneficiaries to ensure payment.
Correct answer: When a provider believes a typically covered service may not be considered medically necessary by Medicare for a specific patient.
An ABN is a form used to inform a Medicare beneficiary before a service is rendered that Medicare is not expected to pay for it because it is not considered "reasonable and necessary" for the patient's condition. This allows the patient to make an informed decision and agree to be financially responsible if Medicare denies the claim. ABNs are not required for services that are never covered by Medicare (statutorily excluded), although a voluntary notice may be given as a courtesy.
Question 4: A durable medical equipment (DME) supplier provides a Medicare patient with a new standard manual wheelchair for home use. Which HCPCS Level II modifier is required to indicate the status of the equipment?
- RR - Rental
- NU - New equipment (Correct answer)
- UE - Used equipment
- LT - Left side
Correct answer: NU - New equipment
HCPCS Level II modifiers are used to provide additional information about a service or supply. For durable medical equipment, modifier -NU is appended to the HCPCS code to specify that the item provided is new equipment. Modifier -RR is used for rentals and -UE is for used equipment.
Question 5: Which of the following statements is TRUE regarding the use of J-codes in HCPCS Level II?
- J-codes are used exclusively to report services in a hospital inpatient setting.
- All J-codes represent a single, standard dosage of 1 mL per unit.
- J-codes represent drugs that are typically administered by a healthcare professional and cannot be self-administered. (Correct answer)
- J-codes are temporary codes used only for experimental drugs.
Correct answer: J-codes represent drugs that are typically administered by a healthcare professional and cannot be self-administered.
J-codes are a subset of HCPCS Level II codes used to identify specific drugs and biologicals that are administered by routes other than oral, such as injections and infusions, which are typically performed by a healthcare professional in an outpatient setting. The billing unit for J-codes varies widely by drug (e.g., per mg, per 10 mg, etc.) and is specified in the code's description.
Question 6: A podiatrist performs routine foot care for a patient with diabetes and peripheral vascular disease. These systemic conditions make the otherwise non-covered service medically necessary. Which category of HCPCS Level II modifiers is used to communicate this medical necessity to Medicare?
- Laterality modifiers (-RT, -LT)
- Q modifiers (-Q7, -Q8, -Q9) (Correct answer)
- Anesthesia physical status modifiers (-P1, -P2, -P3)
- Service-related modifiers (-GY, -GZ)
Correct answer: Q modifiers (-Q7, -Q8, -Q9)
The Q modifiers (-Q7, -Q8, -Q9) are specifically used for podiatry to indicate that routine foot care, which is normally excluded from Medicare coverage, is medically necessary due to the presence of systemic conditions that put the patient at risk. These modifiers describe the specific class of findings documented during the exam.
