2027 Medicare Part B Premium and Deductible
What the 2027 Part B standard premium will be, why it cannot be projected, and the 2026 figures that stand until CMS announces.
Not yet announced No 2027 figure exists yet, from anyone. The Part B premium is not indexed to anything. CMS sets it each November from projected program cost and utilisation, so there is no formula to apply and no honest way to project it. The IRMAA MAGI thresholds that sit on top of it ARE indexed, and those are projected on /irmaa-brackets-2027/.
