HSA Contributions After Medicare: The 6-Month Lookback

Mon, 14 Sep 2026 00:00:00 +0000

What This Means

A health savings account — an HSA — is the tax-free account many people pay into through work to cover medical costs. It comes with one hard condition: you can only put money in for months when you are not on Medicare. The IRS says it bluntly. From the first month you are enrolled in Medicare, the amount you are allowed to add is zero.

The trouble is that people find this out after Medicare has already started — and often after it started on a date in the past. Medicare Part A, the hospital half, can be backdated by up to six months. So money you paid in during, say, March can turn out to have gone in during a month when you were, on paper, already on Medicare.

Opted Out of Medicare Part B: What It Costs to Get Back In

Mon, 14 Sep 2026 00:00:00 +0000

What This Means

Medicare Part B is the half that pays for doctors, tests, outpatient treatment and most equipment. (Part A is the hospital half.) You either turned Part B down when Medicare first offered it, or you filled in form CMS-1763 later to end it. Either way you have no cover for any of that now, and those bills are yours to pay.

Coming back is not simply a matter of changing your mind. For most people it means three separate things:

Small Employer: Medicare Should Have Paid First

Mon, 14 Sep 2026 00:00:00 +0000

What This Means

When you have both Medicare and a health plan through a job, one of them pays the bill first and the other picks up what is left. Which one goes first is not a choice. It is set by rule, and the rule turns on how many people the employer has.

If the employer is large, the work plan pays first and Medicare pays second. If the employer is small, it is the other way round: Medicare pays first, and the work plan pays second.

Switching From Medicare Advantage Back to Medigap

Mon, 14 Sep 2026 00:00:00 +0000

What This Means

Original Medicare pays most of a medical bill, but not all of it. A Medigap policy is private insurance you buy separately to cover the part Medicare leaves you — most importantly the 20% of every doctor’s bill that Original Medicare never pays, which has no yearly limit on it.

Here is the part that matters to you right now. Most of the time, a company selling Medigap is allowed to ask about your health first and then decide. If you have had a heart attack, a cancer diagnosis, diabetes that needed treatment — whatever is on their list — they can charge you more, make you wait before they will cover that condition, or simply refuse to sell you a policy at all. There is no appeal, and it is perfectly legal. The industry word for that check is medical underwriting, and you will see it on application forms. It is the reason people who leave Medigap often cannot get back in.
