Part A (hospital insurance)
Medicare Part A helps cover inpatient hospital care.
If you've worked in the United States and paid Medicare taxes for at least 40 quarters (about 10 years), your Part A coverage is free. If you don't qualify for free Part A, you can purchase Part A coverage from the government.
Some people who are already receiving Social Security benefits are automatically enrolled. Others need to apply through Social Security when they become eligible for Medicare.
When to enroll
If you aren't automatically enrolled in Part A, you can enroll:
- When you first become eligible, by age, disability, or other criteria. This Initial Coverage Election Period (ICEP) lasts 7 months.
- During the annual General Enrollment Period for Medicare Parts A and B: January 1 through March 31 each year. Coverage starts July 1.
Part A covers
- Inpatient care in hospitals, including critical access hospitals, inpatient rehabilitation facilities and long-term care hospitals
- Skilled nursing facilities (not custodial or long-term care)
- Hospice care
- Home health care services
Part A does not cover
- Non-skilled or custodial services including assistance in Activities of Daily Living (ADL)
- Benefits that are covered under Medicare Part B
