The standard Medicare Part B premium is rising to $202.90 per month in 2026, up from $185.00 in 2025, according to figures released alongside the annual Medicare Trustees Report.
That's a jump of nearly $18 a month, or about $215 more per year for the roughly 68 million Americans enrolled in the program.
Part B's annual deductible rises to $283 from $257, meaning beneficiaries pay more out of pocket before coverage kicks in.
Medicare's actuaries point to two main drivers: higher projected spending on outpatient care and a continued shift of costly drugs and procedures from hospital settings into Part B coverage.
When expensive treatments move out of Part A, they land on Part B's ledger, and premiums follow.
Part D drug plan premiums are also in flux.
The average Part D premium is projected to rise modestly, though the $2,000 annual cap on out-of-pocket drug spending remains in place.
That cap has been a genuine relief for people with high prescription costs, even as base premiums climb.
For retirees on fixed incomes, the math matters.
Social Security's cost-of-living adjustment for 2026 is projected around 2.7%, which means for many beneficiaries the premium hike will eat a meaningful chunk of their raise.
Because Part B premiums are typically deducted directly from Social Security checks, the increase often shows up as a smaller deposit rather than a separate bill.
The income-related monthly adjustment amount, or IRMAA, adds surcharges for individuals earning above $106,000 and couples above $212,000, based on tax returns from two years prior.
The thresholds and surcharge tiers shift annually, so a one-time spike in income, like a property sale or Roth conversion, can trigger a higher premium down the road.
If your income has dropped due to a life-changing event like retirement, divorce, or the death of a spouse, you can file Form SSA-44 to request an IRMAA reduction.
It's one of the most underused forms in the Medicare system, and it can save hundreds of dollars a year for people who qualify.
Open enrollment for Medicare Advantage and Part D runs from October 15 through December 7, and it's worth comparing plans even if you're happy with your current one.
Premiums, networks, and drug formularies change every year, and a plan that was cheap in 2025 may not be in 2026.
Here's the bottom line: Medicare Part B is getting more expensive, and the increase will quietly shrink many Social Security checks.
Final Thoughts
The smartest move is to check your income bracket, file for an IRMAA adjustment if your circumstances changed, and treat fall open enrollment as a mandatory annual review rather than an afterthought.
