Why Is My 2026 Medicare Premium Taking My Social Security Raise?

The Raise That Wasn't

Every year, the Social Security Administration announces a cost-of-living adjustment — the COLA — designed to help beneficiaries keep up with inflation. For 2026, that number came in at 2.5%. On the average Social Security retirement benefit of roughly $1,976 a month, that works out to about $49 more per month, or around $588 over the course of the year.

That sounds meaningful. It would be — if Medicare didn't move at the same time.

The Part B premium, which covers doctor visits, outpatient care, and most non-hospital medical services, increased from $185.00 in 2025 to $202.90 in 2026. That's a $17.90 monthly increase — nearly 10 percent in a single year. Because Part B premiums are deducted automatically from Social Security checks for most beneficiaries, millions of retirees opened their January statements and found that their "raise" had shrunk dramatically before it ever touched their bank account.

For a single beneficiary receiving the average Social Security payment, the Part B increase consumed roughly a third of the COLA. For those with below-average benefits — particularly women, who statistically receive lower lifetime earnings-based payments — the premium increase swallowed an even larger share. And for the estimated 13 million married couples where both spouses are on Medicare, the combined household hit was $35.80 per month, or $429.60 over the year. You can see the full breakdown in our 2026 Part B premium analysis.

Why the Premium Jumped So Much This Year

A nearly 10 percent increase in one year isn't normal — at least not recently. Over the five years from 2020 to 2025, the average annual Part B premium increase was around 5 percent. So what changed?

The Centers for Medicare and Medicaid Services pointed to two main drivers. The first is straightforward: projected increases in both the price of healthcare services and the volume of services being used. As the population ages and more beneficiaries use Medicare, program costs rise — and those costs are partially passed along to enrollees through the premium.

The second factor is more technical, but worth understanding. Part B premiums are calculated based on total projected program spending — and that calculation includes what Medicare pays to Medicare Advantage plans on behalf of their enrollees for Part B services. As MA enrollment has grown to cover more than half of all Medicare beneficiaries, the sheer scale of those payments now meaningfully influences what everyone pays, including people in traditional Medicare who never enrolled in an Advantage plan.

There was also a potential wildcard this year that was partially neutralized. Spending on a category of wound care products called skin substitutes had grown to extraordinary levels in recent years, and CMS took action to rein it in through the 2026 Physician Fee Schedule. Without that intervention, the Part B premium would have been roughly $11 higher per month than it already is. The change helped — but the increase still landed hard for people on fixed incomes.

The "Hold Harmless" Rule — and Who It Doesn't Protect

There is a federal protection called the "hold harmless" provision that sounds reassuring. It says that if you receive Social Security benefits and have your Part B premium deducted automatically, your monthly Social Security check cannot actually decrease from one year to the next because of a premium increase. In other words, if the premium rise would otherwise cause your check to go negative, it gets capped.

But here's what the provision doesn't protect against: it simply limits how much of a raise you keep. It does not guarantee you keep any of it. In a year like 2026, where the premium increase outpaced the COLA for lower-benefit recipients, the hold harmless provision kicked in for some — but for many others, the math just barely cleared the threshold, leaving a smaller-than-expected gain on the table.

The hold harmless rule also does not apply to everyone. Beneficiaries subject to IRMAA surcharges — those with higher incomes — receive no such protection. Neither do people who don't receive Social Security benefits and pay their premiums by direct billing. For these groups, the full premium increase hits without a cushion.

What You Can Actually Do About It

The frustrating reality is that most people accept whatever shows up on their statement without knowing there are legitimate ways to reduce what they pay. None of them require fighting the government — they just require knowing the options exist.

If your income has changed since the 2024 tax year — you retired, lost a spouse, sold a property, or experienced another life event that significantly reduced your earnings — you can file for an IRMAA reconsideration with the Social Security Administration. The standard IRMAA calculation looks back two years, which means someone who earned significantly more in 2024 than they will going forward may be stuck paying a surcharge that no longer reflects their current situation. The appeal process exists specifically for this, and it works.

If your income is more modest, you may qualify for one of the Medicare Savings Programs — state-administered assistance programs that can pay your Part B premium entirely, along with deductibles and copays. These programs are significantly underused. Millions of people who qualify have never applied because they didn't know the programs existed or assumed they wouldn't qualify. Our 2026 Medicare costs guide covers eligibility in more detail.

And if you're on a Medicare Advantage plan, the annual enrollment period — which runs each fall from October 15 through December 7 — is your window to compare plans and potentially find one with a Part B premium reduction benefit built in. It won't undo this year's increase, but it's real money going forward. Check our 2026 Medicare Advantage updates to see what's changing.

The system isn't designed to make any of this obvious. But the options are real, and the savings for the right person can be substantial.
