Different parts of the Medicare program cover different aspects of healthcare you may need.

If you receive Social Security checks, you will likely be automatically signed up for Medicare Part A and Medicare Part B when you turn 65. You can opt out of automatic enrollment.

If you don’t receive Social Security, you should sign up for Part A and B and/or Part C and D plans within three months of your 65th birthday — or within six months of your 65th birthday for Medigap policies — to receive full coverage and the lowest premiums.

There are usually late enrollment penalties if you wait to sign up for the various parts of Medicare coverage. Click the links above for more details about how to sign up.

• You were admitted to a hospital as an inpatient — not just under observation or for emergency room care — for at least three consecutive midnights
• You are enrolled in Medicare before your hospital stay

If these conditions are met, Medicare may pay for up to 100 days of rehab therapy services — including skilled nursing care, physical therapy, occupational therapy and speech therapy — if you’re admitted to a Medicare-certified rehab location within 30 days of being discharged from the hospital.

To qualify for coverage, Medicare has designations for where this after-hospital care — called post-acute care — can take place, including:

• Skilled nursing facilities, nursing homes and skilled care centers
• Inpatient rehabilitation facilities
• Long-term care hospitals
