Final answer:
The physician is compensated 80% of the approved amount on a Medicare claim.
Step-by-step explanation:
The correct answer is c. 80% of approved amount.
Accepting assignment on a Medicare claim means that the physician agrees to accept the approved amount for the service as full payment. This means that the physician will be compensated 80% of the approved amount by Medicare, while the remaining 20% may be covered by the patient or a secondary insurance.
For example, if the approved amount for a service is $100, the physician would be compensated $80, and the patient or secondary insurance would be responsible for the remaining $20.
