Annual Enrollment Medicare Advantage (MAPD) Plans

Medicare Advantage Plans for Contra Costa County for 2023

Jump to the Medicare Advantage Plans chart

Medicare Advantage (MAPD) plans are private insurance plans approved and subsidized by Medicare. They offer equivalent benefits to Medicare and are an alternative way of receiving Medicare coverage. You must have both Parts A and B of Medicare to join a Medicare Advantage plan and pay the same premiums, and any applicable income related surcharges and late enrollment penalties as those on Original Medicare.

Almost all Medicare Advantage plans in Contra Costa County are HMO’s. For 2023 we have one new PPO type plan. For HMO plans, you must use the plan’s network providers and get referrals from your primary care physician for specialists. Generally any specialists must be part of the same physician’s group (IPA) as your primary care physician. Joining a Medicare Advantage plan means you may not use your Medicare card outside the plan. All Contra Costa County HMO’s include Part D prescription drug coverage.

Unless you are in your initial Medicare enrollment period or a special enrollment period, you can only join or leave a plan at certain times. Open enrollment occurs each year between October 15th and December 7th. An exception to this rule is offered for a 5-Star Plan.
