The Kaiser Senior Advantage Plan is a replacement for Medicare coverage, according to the University of California. It is a health maintenance organization that manages Medicare benefits for the insured.
Enrollment in Kaiser Senior Advantage gives Medicare coverage to customers by using a closed network of providers. The customer chooses a primary care physician in the network who refers patients to specialists if needed. This plan suits people who want lower out-of-pocket costs and who like one doctor managing their care, states the University of California. Out-of-network services are only approved for emergency situations. Medicare benefits are completely covered by the Kaiser Senior Advantage plan.
