Plan types

How the plan types fit together

Original Medicare is the federal program itself: Part A for hospital care and Part B for medical care. It covers a lot and still leaves some costs for you to pay.

A Medicare Advantage plan, also called Part C, is a private plan approved by Medicare that gives you your Part A and Part B coverage through one plan, usually with a network.

Medicare drug coverage, Part D, is about your prescriptions. Many Medicare Advantage plans include it.

A Medicare Supplement policy, also called Medigap, helps pay some of the costs Original Medicare leaves you to pay. It works with Original Medicare, not with a Medicare Advantage plan.

Which combination fits depends on your doctors, your prescriptions and how you would rather handle costs. That is the conversation worth having before you choose.

Four plan types, and which ones go together

Four plan types, and which ones go together A comparison of four plan types: the ACA Marketplace, Medicare Advantage, Medicare Supplement and Medicare Part D. The Marketplace is for people not on Medicare; the other three are for people on Medicare or turning 65. For each it shows who it is for, what it covers, and when you can enroll: the Marketplace from November 1 to January 15 or 60 days after a life event; Medicare Advantage and Part D from October 15 to December 7, with January 1 to March 31 to switch if you are already in an Advantage plan; and a Medicare Supplement in a one-time six-month window that starts when you have Part B at 65. The two Medicare paths are Medicare Advantage on its own, or Original Medicare with a Supplement and a Part D plan. You pick one path, not both, because a Medigap policy can't be used with a Medicare Advantage plan. Premiums, networks and drug lists differ by plan, county and year, so this compares plan types, not specific plans.
