CADS Medical Necessity & Coverage Criteria 3

Question 1

For Medicare Part B ambulance coverage, which statement about medical necessity is correct?

Accepted Answer

Medical necessity must be documented in the PCR based on the patient's clinical condition at the time of service

Answer

Medicare Part B requires that medical necessity be documented in the PCR based on objective clinical findings at the time of service, not merely because a 911 call was initiated.

Question 2

What does the 'closest appropriate facility' requirement mean for ambulance documentation?

Accepted Answer

Documentation must justify transport to a non-closest facility when a specialty center better meets the patient's clinical needs

Answer

When transporting past a closer facility, documentation must explain why that facility was not appropriate (e.g., no trauma center capability, no cardiac catheterization lab) given the patient's clinical needs.

Question 3

When a patient refuses hospital transport after EMS evaluation and treatment, what must the PCR documentation include?

Accepted Answer

Assessment of mental status, decision-making capacity, risks explained to patient, and confirmation of patient understanding

Answer

Refusal documentation must include mental status assessment, decision-making capacity evaluation, specific risks communicated to the patient, and confirmation that the patient understood those risks.

Question 4

Which assessment finding would BEST support medical necessity for ALS-level transport?

Accepted Answer

New-onset cardiac dysrhythmia requiring ECG monitoring and antiarrhythmic therapy during transport

Answer

An objective clinical finding such as new cardiac dysrhythmia requiring ECG monitoring and medication administration directly supports the need for ALS-level care during transport.

Question 5

What role does the Physician Certification Statement (PCS) play in establishing medical necessity for non-emergency transports?

Accepted Answer

It serves as supporting documentation but cannot substitute for a clinically complete PCR

Answer

The PCS supports medical necessity claims but the PCR remains the primary clinical document; the PCS alone is insufficient without corresponding clinical documentation in the PCR.
