For example, L5100 covers a below-knee molded socket prosthesis; L5976 covers an energy-storing foot (SACH). The L code category is the standard reporting system for all prosthetic and orthotic devices billed to Medicare and most payers.

Question 8

A patient requires compression stockings (gradient compression, 30-40 mmHg) for lymphedema of both lower extremities. Which HCPCS code covers gradient compression stockings above the knee?

  1. A6530
  2. A6531
  3. A6532
  4. A6533 (correct answer)
Explanation: HCPCS A6533 covers gradient compression stocking, above knee length, 30-40 mmHg, each. Code A6530 covers below-knee compression stockings at 20-30 mmHg; A6531 covers below-knee at 30-40 mmHg; A6532 covers below-knee at 40-50 mmHg. Both the length (below vs. above knee) and the compression level (mmHg) determine the specific compression stocking code.

Question 9

A patient receives enteral nutrition through a nasogastric tube — a standard polymeric formula provided in ready-to-use 1 cal/mL density. Which HCPCS code category covers enteral nutrition formulas?

  1. A codes
  2. B codes (correct answer)

Codes B4034-B4036 cover enteral formula products; B4150 covers enteral formula not previously classified; B9000-B9999 cover parenteral nutrition. The B code series specifically captures nutrition support products administered enterally or parenterally, distinct from oral dietary supplements. J codes cover injectable drugs, not nutrition formulas.

Question 10

A patient is transported by ambulance from a scene of a motor vehicle accident to the nearest appropriate hospital. The ambulance service was at the Basic Life Support (BLS) emergency level. Which HCPCS code covers BLS emergency ambulance transport?

  1. A0425
  2. A0426
  3. A0427
  4. A0429 (correct answer)
Explanation: HCPCS A0429 covers ambulance service, basic life support (BLS), emergency transport. Code A0425 covers ground mileage per statute mile; A0426 covers advanced life support (ALS) non-emergency transport; A0427 covers ALS level 1 emergency transport. The level of service (BLS vs. ALS) and the emergency vs. non-emergency status determine ambulance HCPCS code selection.

Question 11

A HCPCS modifier is needed to indicate that a procedure was performed on the left side of the body. Which HCPCS modifier identifies the left side?

  1. RT
  2. FA
  3. LT (correct answer)
  4. TA
Explanation: HCPCS modifier LT (left side) is used to identify procedures performed on the left side of the body for paired structures such as kidneys, lungs, eyes, or bilateral extremities. Modifier RT identifies the right side; FA identifies the left hand, thumb; TA identifies the left foot, great toe. When laterality is required for paired organs or extremities, the LT/RT modifiers are used.

Question 12

A HCPCS modifier is needed to indicate that a service was performed on the right hand, ring finger (4th digit). Which HCPCS modifier identifies the right hand, 4th digit?

  1. F6
  2. F7
  3. F8 (correct answer)
  4. F9
Explanation: HCPCS modifier F8 identifies the right hand, 4th digit (ring finger). The F modifier series covers individual hand digits: FA through F4 for the left hand (thumb through 5th digit) and F5 through F9 for the right hand (thumb through 5th digit). F6 = right hand, 2nd digit; F7 = right hand, 3rd digit; F9 = right hand, 5th digit. F8 specifically designates the right hand, 4th digit and is required when documenting procedures on a specific finger.

Question 13

A patient is fitted with standard single-vision eyeglasses following cataract surgery. Which HCPCS code category covers eyeglasses and vision supplies?

  1. V codes (correct answer)
  2. L codes
  3. E codes
  4. A codes
Explanation: HCPCS V codes (V2100-V2799) cover vision-related supplies including eyeglass lenses, frames, and contact lenses. For example, V2100 covers sphere, single vision, plano to plus or minus 4.00d; V2020 covers frames. The V code series captures all vision-related supplies and optical services. Post-cataract eyeglasses are a Medicare-covered benefit with specific HCPCS V codes.

Question 14

A physician administers an intramuscular injection of methylprednisolone acetate (Depo-Medrol) 80 mg in the office. Which HCPCS code category covers injectable drug products administered in the physician's office?

  1. A codes
  2. E codes
  3. J codes (correct answer)
  4. L codes
Explanation: HCPCS J codes are used to report drugs administered other than orally, including injectable medications such as corticosteroids, chemotherapy agents, and biologics administered in the physician's office or outpatient setting. For methylprednisolone acetate, J1020 (20 mg), J1030 (40 mg), or J1040 (80 mg) would apply. J codes are the standard HCPCS category for separately reportable drug products.

Question 15

A physician administers an infusion of infliximab (Remicade) for Crohn's disease in the office. The infliximab is billed using a HCPCS J code per 10 mg. Which HCPCS code covers infliximab?

  1. J1745 (correct answer)
  2. J0135
  3. J0456
  4. J0881
Explanation: HCPCS J1745 covers injection of infliximab (Remicade), 10 mg. Code J0135 covers adalimumab (Humira); J0456 covers azithromycin; J0881 covers darbepoetin alfa. Each biologic or specialty drug has its own specific J code. Infliximab is reported per 10 mg unit, so the total dose administered divided by 10 determines the number of units to report on the claim.

Question 16

A Medicare patient requires a standard manual wheelchair for home use following a hip replacement. Which HCPCS Level II code covers a standard manual wheelchair?

  1. K0001 (correct answer)
  2. K0004
  3. E1130
  4. E1161
Explanation: HCPCS K0001 covers a standard manual wheelchair — the base code for a non-powered, standard weight wheelchair. Code K0004 covers a high-strength, lightweight wheelchair; E1130 covers a standard wheelchair with fixed arms and swing-away footrests; E1161 covers a manual adult size wheelchair. K0001 is the correct Medicare DME code for a standard manual wheelchair under the K-code wheelchair classification system.

Question 17

A patient is fitted with a custom-fabricated lumbar sacral orthosis (LSO) for spinal stenosis. Which HCPCS code category covers spinal orthoses?

  1. E codes
  2. K codes
  3. A codes
  4. L codes (correct answer)
Explanation: HCPCS L codes cover both prosthetic and orthotic devices. Spinal orthoses — including lumbar sacral orthoses (LSO), thoracolumbosacral orthoses (TLSO), and cervical orthoses — are found in the L0100-L0999 range. For example, L0650 covers a custom-fabricated LSO, sagittal-coronal control. Orthotic codes are selected based on the spinal region, type of control, and whether the device is prefabricated or custom-fabricated.

Question 18

A diabetic patient requires a home blood glucose monitor and test strips. The monitor itself is a piece of durable medical equipment. Which HCPCS code covers a home blood glucose monitor?

  1. E2100
  2. E0607 (correct answer)
  3. A4253
  4. K0553
Explanation: HCPCS E0607 covers a home blood glucose monitor — the standard DME code for a home-use blood glucose testing device. Code E2100 covers a blood glucose monitor with special features (e.g., voice guidance or braille); A4253 covers blood glucose test strips (a supply code, not the monitor itself); K0553 covers a continuous glucose monitor system. For the standard home glucose monitor device, E0607 is the correct code.

Question 19

A physician administers trastuzumab (Herceptin) intravenously for breast cancer treatment. The drug is billed using a HCPCS J code. Which HCPCS code covers trastuzumab?

  1. J9260
  2. J9310
  3. J9355 (correct answer)
  4. J9035
Explanation: HCPCS J9355 covers trastuzumab (Herceptin), 10 mg per injection — used for HER2-positive breast cancer treatment. Code J9260 covers methotrexate sodium; J9310 covers rituximab; J9035 covers bevacizumab (Avastin). Each chemotherapy drug has a specific J code based on the drug name and dosage unit. Accurate drug identification and dose documentation are required for correct J code assignment.

Question 20

A physician completes a Certificate of Medical Necessity (CMN) for a patient requiring home oxygen therapy. Which Medicare requirement does the CMN fulfill?

  1. It serves as the patient's insurance pre-authorization for the DME item
  2. It establishes and documents medical necessity required for Medicare DME coverage (correct answer)
  3. It replaces the HCPCS billing code when submitted to Medicare
  4. It is only required when the patient has a secondary insurance payer
Explanation: A Certificate of Medical Necessity (CMN) documents the physician's order and clinical justification for specific DME items required under Medicare policy — such as home oxygen, power mobility devices, and enteral nutrition. The CMN establishes medical necessity by documenting the diagnosis, clinical parameters, and physician attestation required for CMS reimbursement. It does not serve as a pre-authorization form, does not replace the HCPCS billing code, and is not limited to patients with secondary insurance.
