Paying for care at Serenethos Care Center: Medicare and Medicaid

Serenethos Care Center is certified for both Medicare and Medicaid. Medicare Part A can cover a short skilled-nursing or rehab stay here after a qualifying hospital stay of at least three inpatient days (observation days don't count), for up to 100 days per benefit period. Medicaid can pay for long-term care for residents who meet California's income and asset rules. Being certified doesn't guarantee a Medicaid bed is open, so ask whether the home accepts residents whose Medicaid application is still pending.

In 2026 Medicare covers days 1–20 in full after the Part A deductible ($1,736 per benefit period); for days 21–100 you pay $217 a day; after day 100 you pay all costs. Medicare doesn't pay for long-term custodial care. Medicare's coverage rules.
