What is a Medicare Cost Plan?

what is a medicare cost plan

Medicare Cost Plans are private Medicare HMO plans that are available in some parts of the country. These plans usually require you to use in-network providers for Medicare-covered services, but also give you the flexibility to go out-of-network and be covered through Original Medicare. If you’re in a Medicare Cost Plan, you’re still enrolled in Medicare and part of the Medicare program.

Unlike traditional HMOs, Medicare Cost Plans give members the option to use out-of-network providers and have those health-care services covered through the traditional fee-for-service program. If you see a non-network provider, you’ll pay Original Medicare cost sharing, such as Medicare Part A and Part B coinsurance, copayments, and deductibles.

Medicare Cost Plans vs. Medicare Advantage plans

Medicare Cost Plans are different from Medicare Advantage (Medicare Part C ) plans in a few key ways:

  • You can join a Medicare Cost Plan even if you’re only enrolled in Medicare Part B.
  • You can enroll in a Medicare Cost Plan at any time, as long as the plan is accepting new members.
  • You can disenroll from a Medicare Cost Plan at any time and return to Original Medicare for your Medicare coverage.
  • If your Medicare Cost Plan doesn’t include Medicare prescription drug coverage, you can join a stand-alone Medicare Part D prescription drug plan.
  • Some Medicare Cost Plans only cover Medicare Part B (medical insurance) benefits and don’t cover Medicare Part A (hospital insurance) or prescription drug benefits.
  • Unlike Medicare Cost Plans, Medicare Advantage requires you to have Medicare Part A and Part B, and you’re generally limited in the times you can join, switch, or disenroll from a Medicare Part C plan.
  • Medicare Advantage plans must provide the same Medicare Part A and Part B benefits as Original Medicare; these plans never cover Medicare Part

    B only. If you want prescription drug coverage, you’ll need to get it through a Medicare Advantage Prescription Drug plan, not a stand-alone Medicare Part D plan.

  • Some Medicare Advantage HMO plans have a Point-of-Service option that lets you see out-of-network providers for some services. However, unlike Medicare Cost Plans, these services would still be covered through your Medicare Advantage plan, not Original Medicare.

Is a Medicare Cost Plan right for me?

One advantage of Medicare Cost Plans is they offer the lower costs of a managed-care plan, but the flexibility to go out-of-network and still be covered through Medicare. In contrast, a Medicare Advantage HMO generally won’t cover the cost for non-network health-care services.

A Medicare Cost Plan could be a good option if you travel frequently or if you live out of your plan’s service area for a large part of the year. With a Medicare Cost Plan, you can still get Medicare-covered services outside of your plan’s provider network.
