CAC CAC Medicare Coverage and Medical Necessity for Ambulance Transport 1 — Questions and Answers
Question 1: What is the Medicare definition of 'medical necessity' for ambulance transport coverage?
- Transport is necessary because the patient's condition requires ambulance-level care and no other means is medically appropriate (Correct answer)
- Transport is requested by a physician
- Transport occurs to a hospital
- Transport is for an emergency condition only
Correct answer: Transport is necessary because the patient's condition requires ambulance-level care and no other means is medically appropriate
Medicare defines medically necessary ambulance transport as when the patient's condition requires ambulance-level services and the use of any other mode of transportation would endanger the patient's health.
Question 2: Under Medicare, which level of ambulance service covers Basic Life Support (BLS) non-emergency transport?
- A0428 (Correct answer)
- A0427
- A0426
- A0432
Correct answer: A0428
HCPCS code A0428 is the correct code for BLS non-emergency ambulance transport under the Medicare Ambulance Fee Schedule.
Question 3: Which Medicare condition of coverage requires that a Physician Certification Statement (PCS) be obtained for non-emergency ambulance transports?
- Repetitive non-emergency transports (Correct answer)
- All BLS transports
- All ALS transports
- Inter-facility transports only
Correct answer: Repetitive non-emergency transports
Medicare requires a Physician Certification Statement for repetitive non-emergency transports (3 or more within a 60-day period) to establish medical necessity.
Question 4: What is the Medicare 'closest appropriate facility' rule for ambulance destination coverage?
- Medicare covers transport to the nearest facility capable of treating the patient's condition (Correct answer)
- Medicare covers transport to the patient's preferred hospital
- Medicare covers transport to any in-network facility
- Medicare covers transport to the facility requested by the physician
Correct answer: Medicare covers transport to the nearest facility capable of treating the patient's condition
Medicare requires that the ambulance transport the patient to the nearest appropriate facility that can provide necessary treatment, not necessarily the patient's or family's preferred destination.
Question 5: Under the Medicare Ambulance Fee Schedule, what does the 'base rate' component of reimbursement cover?
- The level of service provided (BLS/ALS) regardless of distance (Correct answer)
- Only the first 10 miles of transport
- Supplies and medications used during transport
- Personnel costs only
Correct answer: The level of service provided (BLS/ALS) regardless of distance
The base rate covers the level of service (e.g., BLS, ALS1, ALS2) and is reimbursed regardless of transport distance; mileage is billed separately.
Question 6: What is the Medicare coverage rule for air ambulance transport?
- Covered when the patient's condition requires rapid transport and ground transport is not appropriate or available (Correct answer)
- Covered for all emergencies regardless of ground availability
- Covered only for trauma patients
- Covered based solely on transport distance
Correct answer: Covered when the patient's condition requires rapid transport and ground transport is not appropriate or available
Medicare covers air ambulance when the patient's medical condition requires immediate and rapid transport that ground ambulance cannot provide, or when geographic barriers make ground transport impossible.
