Final answer:
The patient must sign an Advance Beneficiary Notice (ABN) if Medicare does not cover the procedure.
Step-by-step explanation:
The correct answer is D. Advance Beneficiary Notice (ABN).
When a procedure is not covered by Medicare, the patient must be notified and is required to sign an Advance Beneficiary Notice (ABN). This form explains that the patient may be responsible for the full cost of the procedure and acknowledges that they understand and agree to pay for it.
For example, if a patient needs a cosmetic procedure that is not deemed medically necessary by Medicare, they would be required to sign an ABN to indicate their understanding of the financial responsibility.
