The short answer

Once you enroll in any part of Medicare, you can no longer contribute to a Health Savings Account (HSA). You can still spend money already in the account, but new contributions must stop.

The full explanation

An HSA, or Health Savings Account, is a tax-advantaged account that works alongside a high-deductible health plan. The IRS rules are clear on this: the moment you enroll in Medicare Part A or Part B, you lose eligibility to contribute new money to an HSA. That applies even if you keep other non-Medicare coverage.Here's where people get tripped up. Part A coverage can be backdated up to six months when you sign up late. If that happens, you technically became ineligible six months ago, and any HSA contributions made during that window could trigger a tax penalty. So if you're still working and contributing to an HSA, you'll want to stop contributions a few months before you plan to enroll in Medicare, just to be safe.The money already sitting in your HSA doesn't disappear. You can keep using it to pay Medicare premiums, deductibles, copays, and other qualified medical expenses, tax-free. It just becomes a spending account rather than a savings account. Talk to a tax advisor or a Medicare counselor before making changes, since the timing matters quite a bit here.

In 

Ohio

 specifically

Ohio beneficiaries should pay close attention to local hospital systems and doctor networks before enrolling, because plan availability does not guarantee your preferred providers are in network. Ohio residents can also get free Medicare counseling through the Ohio Senior Health Insurance Information Program.

What this means for you

For you, this means if you're still contributing to an HSA and getting close to Medicare enrollment, plan your stop date carefully to avoid an unexpected tax penalty.
