Medicare’s Premium Goes Up in January and Her Social Security Check Won’t Go Down a Penny. A Decades-Old Rule Says It Can’t, and Whether It Protects You Comes Down to One Comparison
A federal rule dating back decades quietly protects millions of Social Security recipients when Medicare premiums spike, but whether it shields your check or leaves you absorbing the full cost comes down to a single comparison most retirees never think…

Every January, Social Security shows two changes: the cost-of-living adjustment (COLA, the annual inflation raise) and a new Medicare Part B premium. Part B covers doctor and outpatient care, and its premium usually comes from the check. When the premium rises more than the raise, one figure can’t drop for millions of retirees: the net dollar amount paid. That’s the Medicare hold harmless provision. Whether it covers you depends on one comparison.
What the Hold Harmless Rule Guarantees
If your Part B premium is deducted from Social Security, a higher premium can’t reduce that payment amount year over year. When the premium increase exceeds your COLA in dollars, your premium rises only as far as the COLA covers. The rule protects your check size.
The legal basis is Section 1839(f) of the Social Security Act (42 U.S.C. 1395r). Federal Register notices call it the “hold-harmless” provision.
Why It Only Kicks In During Lean COLA Years
The rule matters only when the premium’s dollar increase exceeds your COLA’s dollar increase. In 2026, benefits rose 2.8%, while the standard premium went up $17.90, from $185 to $202.90. A $3,000 monthly benefit increased by about $84, easily covering the higher premium. In 2022, it applied to only 1.5% of Part B enrollees. A near-zero COLA extends the rule’s reach: heading into 2017, about 70% of enrollees were expected to be protected.
Neither 2027 figure has been published. The COLA comes out October 14, 2026, when September inflation data is released. The 2027 Part B premium hasn’t been announced either, though Medicare trustees have projected a $6.60 increase to $209.50. Last year, the Centers for Medicare & Medicaid Services released the 2026 premium on November 14, 2025.
Groups Left Outside the Protection
- Higher-income enrollees paying the income-related monthly adjustment amount (IRMAA, a surcharge on the standard premium) are explicitly excluded by law.
- New enrollees in Medicare aren’t covered (new enrollees).
- Anyone who doesn’t have the premium deducted from a Social Security check is out, including those who pay by bill.
- Low-income enrollees whose Part B premiums Medicaid pays fall under a separate arrangement.
Who Picks Up the Tab for Protected Retirees
The standard premium covers 25% of expected Part B costs, with federal general revenues covering the rest. In years when the rule protects a large share of enrollees, those left out subsidize the increasing cost through higher premium increases.
The protection is temporary: once COLAs grow faster than Medicare costs, protected enrollees make up the difference with additional Medicare premium boosts until they reach the standard amount.
How to Keep Your Protection From Disappearing
- Know the surcharge thresholds: for 2026, IRMAA starts above $109,000 of modified adjusted gross income (MAGI) for individual filers and above $218,000 for joint filers. Moving one bracket over raises the total premium to $284.10 and eliminates hold harmless protection.
- Plan around the two-year lookback. IRMAA is based on income from two years ago, so 2025 income sets 2027 premiums. A Roth conversion, property sale, or large retirement account withdrawal can push you over a threshold two years later.
- Count both spouses: a married couple both on Medicare pays the surcharge for each of you.
- File Form SSA-44 after a life-changing event like retirement, reduced work hours, marriage, divorce, a spouse’s death, loss of income, or an employer settlement payment. Call 800-772-1213 or file online.
Spotting a Check That Looks Wrong
Social Security’s annual COLA notice shows your gross benefit, Medicare deduction, and net payment, posted in your my Social Security account. Compare this year’s net payment with last year’s. If it dropped and none of the exceptions apply, contact Social Security. If you get an IRMAA determination, the agency’s letter with your premium amount(s) and the reason explains how to appeal (IRMAA is one of several Medicare costs that catch retirees off guard, and we covered the rest in a free guide to Medicare’s hidden bills).
Run the Two-Number Test Once 2027 Figures Land
When the COLA and 2027 premium are both out, write down two numbers: your COLA’s dollar increase and the Part B premium’s dollar increase. If the premium increase is bigger and no exceptions apply, hold harmless caps your premium so your check doesn’t decrease. If the COLA increase is bigger, the rule does nothing for you this year.
