Medicare covers a short stay after a qualifying hospital admission, for rehabilitation, not for long-term custodial care. Long stays are paid privately or by Medicaid once assets are spent down.
Medicare Care Compare publishes inspection results, staffing levels and quality measures for every certified home.
Why it matters
The distinction between a Medicare rehabilitation stay and a long-term stay decides who pays, and families are often surprised by it.
