All questions

Question 1

A 70-year-old with diabetes receives therapeutic shoes (A5500) and one set of inserts; the claim must show the left shoe only per dispensing record. Identify the correct modifier for the DME provided.

  1. A5500 RT
  2. A5500 LT (correct answer)
  3. A5500 KX
  4. A5500 GA
Explanation: This question tests the application of HCPCS Level II modifiers in medical billing. HCPCS Level II modifiers are additional codes used to provide more information about a service or procedure, such as what was performed, the rationale, or any special circumstances. In this scenario, the passage describes therapeutic shoes dispensed for the left side only, needing a laterality modifier for precise billing. The correct answer is choice B because LT specifies the left side, aligning with the dispensing record for the left shoe. Choice A is incorrect because RT denotes the right side, which is not mentioned in the record. To teach this concept: Encourage familiarity with anatomical modifiers like LT and RT, and provide practice scenarios requiring side-specific identification in diabetic supply billing.

Question 2

A 67-year-old receives a right and left knee braces (L1832) on the same date; the supplier must show the item was provided bilaterally. Identify the correct modifier for the DME provided.

  2. L1832 RT
  3. L1832 LT
  4. L1832 KX
Explanation: This question tests the application of HCPCS Level II modifiers in medical billing. HCPCS Level II modifiers are additional codes used to provide more information about a service or procedure, such as what was performed, the rationale, or any special circumstances. In this scenario, the passage describes knee braces for both sides on the same date, needing a bilateral modifier. The correct answer is choice A because 50 indicates bilateral provision, showing both items dispensed. Choice B is incorrect because RT specifies only the right side. To teach this concept: Encourage familiarity with bilateral modifier 50 for orthotics, and provide practice scenarios for same-day bilateral dispensing.

Question 3

A 71-year-old receives a new cane (E0100) after gait evaluation; it is dispensed as a purchase with proof of delivery and no prior cane billed. Identify the correct modifier for the DME provided.
