CADS Medical Necessity & Coverage Criteria 1 — Questions and Answers
Question 1: What is the primary requirement that must be documented to justify ambulance transport reimbursement under Medicare?
- The patient's insurance information and policy number
- That the patient's condition required the response and services of trained EMS personnel and that transport by other means would be contraindicated (Correct answer)
- The ambulance unit's vehicle identification number
- The crew members' certification levels only
Correct answer: That the patient's condition required the response and services of trained EMS personnel and that transport by other means would be contraindicated
Medicare requires documentation that the patient's condition required trained EMS personnel and that transport by other means would have been contraindicated or medically inappropriate.
Question 2: Which patient condition must be documented to support medical necessity for a Basic Life Support (BLS) emergency transport?
- The patient requires intravenous medication administration during transport
- The patient's condition requires immediate ALS interventions only
- The patient has a condition that could deteriorate during transport, requiring BLS-level monitoring (Correct answer)
- The patient is ambulatory but requests ambulance service
Correct answer: The patient has a condition that could deteriorate during transport, requiring BLS-level monitoring
BLS transport medical necessity requires documentation that the patient's condition could reasonably be expected to require BLS-level monitoring or interventions during transport.
Question 3: According to Medicare guidelines, which of the following ambulance transport scenarios would generally NOT be covered?
- A patient with severe chest pain transported to the nearest emergency room
- A fully ambulatory patient transported to a routine follow-up appointment by personal preference (Correct answer)
- A patient with acute stroke transported to a certified stroke center
- A patient with severe respiratory distress transported after 911 activation
Correct answer: A fully ambulatory patient transported to a routine follow-up appointment by personal preference
Medicare does not cover ambulance transport for patients who are fully ambulatory and capable of traveling by other means, even if they prefer ambulance service.
Question 4: In EMS documentation, 'medically necessary' ambulance transport means:
- Any transport requested by a physician regardless of patient condition
- Transport that is the least expensive option available to the patient
- Transport where the patient's condition requires the level of service provided and alternative transport would be contraindicated (Correct answer)
- Transport pre-approved by the patient's insurance carrier prior to service
Correct answer: Transport where the patient's condition requires the level of service provided and alternative transport would be contraindicated
Medical necessity means the patient's medical condition requires the specific level of ambulance service provided and that transport by any other means would be contraindicated or medically inappropriate.
Question 5: Which document serves as the foundational record for establishing medical necessity in ambulance transport?
- The hospital discharge summary completed after arrival
- The Patient Care Report (PCR) (Correct answer)
- The billing invoice submitted to the payer
- The dispatch log from the communications center
Correct answer: The Patient Care Report (PCR)
The Patient Care Report (PCR) is the primary clinical and operational document that captures the patient's condition, assessment findings, and interventions that establish medical necessity.
Question 6: To document ALS Level 1 (ALS1) medical necessity, which of the following must be recorded?
- Only that an ALS-certified unit responded to the call
- That an ALS assessment was performed by qualified ALS personnel, even if no ALS interventions were required (Correct answer)
- That ALS interventions such as cardiac monitoring, IV access, or medication administration were all performed
- That the patient verbally requested advanced life support care
Correct answer: That an ALS assessment was performed by qualified ALS personnel, even if no ALS interventions were required
For ALS1, Medicare requires documentation that an ALS assessment was performed by qualified ALS personnel, which may or may not result in actual ALS interventions.
Question 7: For a non-emergency scheduled transport to qualify as medically necessary under Medicare, the patient must primarily meet which criterion?
- The patient must have been discharged from a hospital within the past 30 days
- The patient must be unable to be transported safely by any other available means due to their medical condition (Correct answer)
- The patient must have a physician order for the transport dated within 30 days
- The patient must be enrolled in a Medicare Advantage plan
Correct answer: The patient must be unable to be transported safely by any other available means due to their medical condition
Non-emergency transport medical necessity requires that the patient's medical condition prevents them from being transported safely by any other available means.
