Medicare Part A (hospital insurance) is one part of Original Medicare and covers many inpatient services. Medicare Part C (Medicare Advantage) is an alternative coverage option to Original Medicare that is provided by private insurance companies.

Original Medicare consists of Part A and Part B. These two parts cover many inpatient and outpatient treatments and services.

Medicare Part C (Medicare Advantage) plans have to provide the same coverage as Original Medicare. These plans also typically offer additional benefits that are not covered by Original Medicare.
