On September 27, 2022, the Centers for Medicare & Medicaid Services (CMS) released the 2023 premiums, deductibles, and coinsurance amounts for the Medicare Part A and Part B programs, and the 2023 Medicare Part D income-related monthly adjustment amounts.
Medicare Part B Premium and Deductible
Medicare Part B covers physician services, outpatient hospital services, certain home health services, durable medical equipment, and certain other medical and health services not covered by Medicare Part A.
Each year the Medicare Part B premium, deductible, and coinsurance rates are determined according to the Social Security Act. The standard monthly premium for Medicare Part B enrollees will be $164.90 for 2023, a decrease of $5.20 from $170.10 in 2022. The annual deductible for all Medicare Part B beneficiaries is $226 in 2023, a decrease of $7 from the annual deductible of $233 in 2022.
The 2022 premium included a contingency margin to cover projected Part B spending for a new drug, Aduhelm. Lower-than-projected spending on both Aduhelm and other Part B items and services resulted in much larger reserves in the Part B account of the Supplementary Medical Insurance (SMI) Trust Fund, which can be used to limit future Part B premium increases. The decrease in the 2023 Part B premium aligns with the CMS recommendation in a May 2022 report that excess SMI reserves be passed along to people with Medicare Part B coverage.
Beginning in 2023, certain Medicare enrollees who are 36 months post kidney transplant, and therefore are no longer eligible for full Medicare coverage, can elect to continue Part B coverage of immunosuppressive drugs by paying a premium. For 2023, the immunosuppressive drug premium is $97.10.
