Which Medicare program is voluntary and assists with physician services?

Part B of Medicare is the program that is voluntary and provides assistance specifically for physician services. This component of Medicare primarily covers outpatient care, including visits to doctors, preventive services, laboratory tests, and some outpatient therapies.

Beneficiaries can choose whether or not to enroll in Part B, which differentiates it from Part A, which is generally automatic for those who have worked and paid Medicare taxes for a certain period. Part C, also known as Medicare Advantage, offers an alternative way to receive Medicare benefits but does not focus solely on outpatient services like Part B does. Part D is specifically for prescription drug coverage, not for physician services.

Thus, Part B plays a crucial role in ensuring that beneficiaries have access to essential healthcare services delivered by physicians while allowing them the option to decide their participation.
