Seniors navigating health coverage often face questions about how **Obamacare (the Affordable Care Act, ACA)** and **Medicare** interact, especially when their eligibility or benefits seem to overlap. Understanding this overlap is crucial because it affects how seniors access care, what costs they might face, and how to maximize their benefits without confusion or gaps.
First, it’s important to clarify what each program is and who it serves. **Medicare** is a federal health insurance program primarily for people aged 65 and older, as well as some younger people with disabilities. It provides coverage for hospital care (Part A), medical services (Part B), and prescription drugs (Part D), among other options. **Obamacare**, or the ACA, is a broader health reform law that created health insurance marketplaces and expanded Medicaid in many states, mainly targeting people under 65 who don’t qualify for Medicare but need affordable coverage.

### Key Points Seniors Need to Know About the Overlap

If you have an ACA marketplace plan when you turn 65, you should enroll in Medicare because Medicare covers many services that ACA plans do not, and it’s illegal to keep marketplace coverage once you have Medicare Part A and Part B.
2. **You cannot use ACA marketplace subsidies if you have Medicare.** The premium tax credits and cost-sharing reductions available through the ACA marketplaces are not available to people who are eligible for Medicare. If you try to keep marketplace coverage after Medicare eligibility, you may have to pay back subsidies.
3. **Medicare and Medicaid can wor
