Medicare, the federal health insurance program for people age 65 and older, people with End Stage Renal Disease, and younger adults with disabilities, is an important source of coverage for many people living with HIV. Over the past four weeks there has been great interest in the opening of the Affordable Care Act’s Health Insurance Marketplace. As a result, some people with Medicare may have questions about how all of this affects them. Also, because the Medicare open enrollment period is overlapping with the beginning of the Health Insurance Marketplace enrollment period, many people with Medicare have questions about what they need to do to ensure their health coverage continues. (The Medicare open enrollment period runs October 15-December 7, 2013 while the Health Insurance Marketplace launched on October 1, 2013 and its open enrollment period runs through March 31, 2014). We at wanted to share the following information with our readers who may have questions.

Your Medicare Coverage is Protected

Medicare isn’t part of the Health Insurance Marketplace established by Affordable Care Act (sometimes called “Obamacare”), so you don't have to replace your Medicare coverage with Marketplace coverage. No matter how you get Medicare, whether through Original Medicare or a Medicare Advantage Plan, you’ll still have the same benefits and security you have now.

In addition, if you have Medicare, you’re considered covered for the purpose of satisfying the health care law’s individual mandate that everyone must have health coverage.

If I’m on Medicare, What Do I Need to Do on

In short: nothing. Medicare isn’t part of the Health Insurance Marketplace, so you don’t need to do anything in the new online Marketplace. In fact, you can’t purchase a plan in the new Individual Marketplace since it is illegal to sell Individual Marketplace coverage to Medicare beneficiaries. The Marketplace is designed to help people who don’t have any health coverage. If you have health coverage through Medicare, you’re considered covered and don’t need to replace your Medicare with coverage from the Marketplace. The Marketplace won’t have any effect on your Medicare coverage.

Note: The Marketplace doesn’t offer Medicare Supplement Insurance (Medigap) policies or Part D drug plans. For information on these programs, visit
