Medicare isn’t part of the Health Insurance Marketplace, so if you have Medicare coverage now you don’t need to do anything. If you have Medicare, you’re considered covered.
The Marketplace won’t affect your Medicare choices or benefits. No matter how you get Medicare, whether through Original Medicare or a Medicare Advantage Plan (like an HMO or PPO), you won’t have to make any changes.
IMPORTANT: The Marketplace doesn’t offer Medicare supplement (Medigap) insurance or Part D drug plans.
If you have Medicare Part A (Hospital Insurance), you’re considered covered under the health care law and don’t need a Marketplace plan. But having only Medicare Part B (Medical Insurance) doesn’t meet this requirement.
TIP: If you have only Medicare Part B, you aren’t considered to have minimum essential coverage. This means you may have to pay the fee that people who don’t have coverage may have to pay.
