California Medicare Advantage Plans

Medicare Advantage plans offer members access to a network of contracted physicians and hospitals, but also allow them the flexibility to seek covered services from outside of the contracted network. Members do not need a referral for specialty care.

Medicare Advantage plans cover benefits in addition to those covered under Original Medicare. Residents in some areas have several plans from which to choose. The plans include an integrated Medicare Part D prescription drug benefit.

Health Maintenance Organization (HMO) plans use a network of contracted local physicians and hospitals to provide member care. Generally, members must use these care providers to receive benefits for covered services, except in emergencies. Some HMO plans do not require referrals for specialty care.
