A Medicare Cost plan, according to the Centers for Medicare and Medicaid (CMS) is defined as:

A type of [Medicare Advantage] HMO. These plans may work in much the same way, and have some of the same rules, as Medicare Advantage plans. In a Medicare Cost Plan, if you go to a non-network provider, the services are covered under the Original Medicare Plan. You would pay the Medicare Part A and Part B coinsurance and deductibles.

A Medicare Cost plan can include Medicare Part D drug coverage (MAPD) or a separate stand-alone Medicare Part D prescription drug plan (PDP) can be added to a Cost plan.

The CMS Medicare & You document adds more information about Medicare Cost plans:

• In general, you can join even if you only have Part B.
• If you have Part A and Part B and go to a non-network provider, Original Medicare covers the services. You’ll pay the Part A and Part B coinsurance and deductibles.
• You can join anytime the Medicare Cost Plan is accepting new members.
• You can leave anytime and return to Original Medicare.
• You can get your Medicare drug coverage from either the Medicare Cost Plan (if offered) or you can join a Medicare drug plan. Even if the Medicare Cost Plan offers drug coverage, you can choose to get drug coverage from a separate  Medicare drug plan.

Note: You can add or drop Medicare drug coverage only at certain times

Please also note:  Medicare Cost Plans are available only on a limited basis

The availability of Medicare Cost plans across the country remains limited, with 57 Medicare Cost Plans offered in 2024, down from 59 plans in 2023 (out of approximately 5,377 Medicare Advantage plans offered in 2024).
