Certified Medical Assistant (CMA AAMA)Administrative: Billing, Coding and SchedulingMedium

A Medicare patient is scheduled for a service that the physician believes may not be considered medically necessary by Medicare. Which document should the office provide to the patient before the service is rendered so the patient can be informed of potential financial responsibility?

  1. AExplanation of Benefits
  2. BAdvance Beneficiary Notice of Noncoverage (ABN)
  3. CCertificate of Medical Necessity
  4. DHIPAA Notice of Privacy Practices
Show answer & explanation

Correct answer: B. Advance Beneficiary Notice of Noncoverage (ABN)

An Advance Beneficiary Notice of Noncoverage (ABN) is given to Medicare beneficiaries before a service is performed when the provider believes Medicare may deny payment due to lack of medical necessity; it informs the patient they may be financially responsible if Medicare denies the claim. The EOB is issued after claim processing, the Notice of Privacy Practices addresses HIPAA rights, and a Certificate of Medical Necessity is used for certain DME items, not general services.

Why the other options are wrong

  • A. An EOB is issued after a claim is processed, not before the service.
  • C. A Certificate of Medical Necessity applies specifically to certain durable medical equipment claims.
  • D. The Notice of Privacy Practices explains HIPAA rights, unrelated to payment liability.

Advance Beneficiary Notice (ABN)

A written notice given to a Medicare beneficiary before a service is provided, informing them that Medicare may not cover the service and that they may be financially responsible if it is denied.

  • Must be given before the service, not after
  • Used when medical necessity is in question under Medicare guidelines
  • Allows the patient to choose to receive the service and accept potential payment liability

Memory trick: ABN = 'Are you willing to pay Before we begin, if Not covered?'
