Medicare Part A: Hospital Insurance

What it covers:

  • Hospital inpatient stays 
  • Home health care

  • Skilled nursing facility care: Covers skilled nursing care for a limited time (on a short-term basis) if you meet specific criteria.
  • Hospice care: Medicare covers most hospice care costs.
  • Home health care: Medicare generally covers short-term home health care if you meet certain conditions.
