Does Villa Siena take Medicare and Medicaid?
Villa Siena is certified for Medicaid only, so Medicare won't pay for a stay here.
Certification isn't a promise of an open bed. Ask how many Medicaid beds it has free and whether it keeps residents who move from Medicare to Medicaid. Our guide explains what Medicare pays for.
