Does Abbey Senior Health take Medicare and Medicaid?
Yes to both. Abbey Senior Health is certified for Medicare and Medicaid. Medicare can pay for a short skilled stay after a qualifying hospital stay; Medicaid can pay for long-term care once you qualify.
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.
