Medicare's Part B premium has climbed again in 2026, and for millions of older Americans living on fixed incomes, the increase is anything but abstract. The standard monthly premium is now $185.00, up from $174.70 in 2025. That $10.30 monthly jump translates to $123.60 more per year coming out of Social Security checks or bank accounts. For someone receiving an average Social Security retirement benefit, that's a meaningful slice of income — and it arrives at a time when grocery bills, housing costs, and prescription drug prices remain elevated.
What makes this particularly difficult for many beneficiaries is the relationship between Part B premiums and Social Security's annual cost-of-living adjustment. The 2026 COLA was set at 2.5%, which added roughly $50 to $60 per month for the average retiree. But the Part B premium increase, combined with any rise in Part D drug plan costs, can quietly absorb a significant portion of that raise before it ever reaches a beneficiary's pocket. This is sometimes called the "COLA erosion" effect — and it's a recurring frustration for people who expect a raise but see little change in their take-home benefit. Higher earners face an even steeper climb: beneficiaries with individual incomes above $106,000 (or $212,000 for couples) pay Income-Related Monthly Adjustment Amounts, or IRMAA surcharges, that can push their total Part B premium to $259.70, $370.00, or higher depending on their income bracket.
Part B covers a broad range of essential services — outpatient doctor visits, preventive screenings, durable medical equipment, mental health services, and most chemotherapy administered in a clinical setting. Because it's so central to day-to-day healthcare, opting out isn't a realistic option for most people. That's what makes premium increases feel inescapable. Unlike Part D drug plans, which beneficiaries can switch during the Annual Enrollment Period (October 15 through December 7), Part B premiums are set nationally by CMS each fall and apply uniformly to everyone enrolled in Original Medicare or Medicare Advantage. There's no shopping around for a lower Part B rate.
One of the most underutilized tools for addressing Part B affordability is the Medicare Savings Program (MSP), a set of four state-administered programs that can help pay Part B premiums — and in some cases, deductibles and cost-sharing — for people with limited income and assets. The Qualified Medicare Beneficiary (QMB) program, for example, covers the Part B premium entirely for individuals with incomes at or below roughly $1,275 per month in 2026 (amounts vary slightly by state). The Specified Low-Income Medicare Beneficiary (SLMB) program covers the premium for those with slightly higher incomes. Critically, enrollment in an MSP also automatically qualifies beneficiaries for the Extra Help program, which reduces Part D drug costs. Yet millions of eligible beneficiaries are not enrolled — largely because the application process requires reaching out to your state Medicaid office, and many people don't know they qualify. If your monthly income is under $1,600 as an individual or $2,100 as a couple, it's worth calling your State Health Insurance Assistance Program (SHIP) counselor or visiting Medicare.gov to check eligibility.
For beneficiaries who received an IRMAA surcharge based on income from two years ago — 2024 income determines 2026 IRMAA — there is a formal appeals process if your financial situation has changed significantly. Life-changing events such as retirement, divorce, the death of a spouse, or loss of income-producing property can qualify you to request a reconsideration using Form SSA-44. This is filed directly with the Social Security Administration, not CMS, and can result in a reduced or eliminated surcharge going forward.
The broader policy picture is one that researchers and advocates have flagged for years: Medicare's cost-sharing structure was not designed with today's income landscape in mind. Part B's 20% coinsurance — with no out-of-pocket cap in Original Medicare — means that a beneficiary undergoing cancer treatment or managing a chronic condition can face thousands of dollars in annual costs on top of premiums. Medigap supplemental insurance can cover much of that exposure, but premiums for those plans have also risen, and in most states, beneficiaries who didn't enroll when they first became eligible face medical underwriting that can make coverage expensive or unavailable. The exception is a small but growing list of states — including California, Oregon, Nevada, and New York — that offer birthday rule or guaranteed issue protections allowing beneficiaries to switch Medigap plans without underwriting during specific annual windows.
The bottom line for 2026 is that affordability pressure on Medicare beneficiaries is real and multidimensional. Rising Part B premiums are one piece of a larger puzzle that includes drug costs, supplemental coverage expenses, and the limits of Social Security income growth. Understanding what programs exist — and actively applying for them — remains the most direct path to managing these costs.
