The short answer

Original Medicare Part A covers hospital stays fully for the first 60 days after you meet the deductible. After that, you pay a daily coinsurance amount. Costs increase significantly after day 90. Exact amounts change each year.

The full explanation

Most people know Medicare helps pay for hospital stays, but the cost structure has some real cliffs in it that can catch people off guard. Here is how it works under Original Medicare. You pay the Part A deductible when you are admitted. That covers days one through 60 of a single benefit period. Starting on day 61, you owe a daily coinsurance amount. That number changes each year, so check Medicare.gov for the current figure. From day 91 onward, costs jump considerably. These days are called lifetime reserve days, and you only get 60 of them total across your entire lifetime. Once those are gone, Medicare stops paying for that stay entirely. Very few people hit these limits, but a serious illness or long recovery can get there faster than you think. This is one of the main reasons people add a Medicare Supplement plan, sometimes called Medigap, or a Medicare Advantage plan. Both can reduce or eliminate these out-of-pocket costs, though details vary by plan.

Ohio

 specifically

In Ohio, Medicare plan options usually vary by county, and larger metro areas like Franklin, Cuyahoga, Hamilton, and Summit tend to have more Medicare Advantage competition than smaller counties. 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 a long hospital stay without additional coverage could get expensive quickly, and it is worth understanding how a supplement or Advantage plan might protect you from those costs.
