Each year, the Medicare Part B premium, deductible, and coinsurance rates are determined according to provisions of the Social Security Act. The standard monthly premium for Medicare Part B enrollees will be $202.90 for 2026, an increase of $17.90 from $185.00 in 2025. The annual deductible for all Medicare Part B beneficiaries will be $283 in 2026, an increase of $26 from the annual deductible of $257 in 2025.
According to CMS, the increase in the 2026 Part B standard premium and deductible is mainly due to “projected price changes and assumed utilization increases that are consistent with historical experience.”
