CADS Ambulance Billing & Reimbursement Flashcards

Which document must an ambulance service obtain when a Medicare beneficiary does not meet medical necessity criteria but still requests transport?

Answer: Advance Beneficiary Notice (ABN)

An Advance Beneficiary Notice (ABN) must be given to Medicare patients before transport when the service may not be covered due to lack of medical necessity, informing them of potential cost liability.

Under Medicare ambulance billing, what is the 'closest appropriate facility' rule?

Answer: Medicare only reimburses transport to the nearest facility capable of treating the patient's condition

Medicare's closest appropriate facility rule states that reimbursable mileage is limited to the distance to the nearest facility capable of providing the necessary level of care for the patient's condition.

Which element of ambulance documentation is most critical for supporting the 'unable to be transported by other means' criterion?

Answer: Detailed description of the patient's physical condition and mobility limitations

A thorough clinical description of the patient's physical or mental condition that prevents safe transport by wheelchair van, private vehicle, or other means is the core documentation needed to establish medical necessity.

What is a 'clean claim' in the context of ambulance billing and documentation?

Answer: A claim submitted with all required data elements, no errors, and supporting documentation

A clean claim is one that contains all required fields, correct coding, appropriate modifiers, and supporting PCR documentation, allowing the payer to process it without requesting additional information.

Which federal law prohibits an ambulance service from billing a patient beyond the Medicare-approved amount when the service accepts assignment?

Answer: Medicare's limiting charge rule under 42 CFR

Under Medicare assignment, the ambulance service agrees to accept the Medicare-approved amount as payment in full and cannot balance-bill the patient beyond their cost-sharing amounts.

In ambulance billing, what is the significance of documenting the patient's 'chief complaint' accurately on the PCR?

Answer: It drives ICD-10 code selection and supports medical necessity for the level of service billed

The chief complaint directly informs ICD-10-CM diagnosis code selection and provides the clinical foundation for justifying the level of ambulance service billed to the payer.
