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.

Medicare Open Enrollment and Medicare Savings Programs

Medicare Open Enrollment for 2023 will begin on October 15, 2022, and ends on December 7, 2022. During this time, people eligible for Medicare can compare 2023 coverage options between Original Medicare, Medicare Advantage, and Part D prescription drug plans. In addition to the soon-to-be-released premiums and cost-sharing information for 2023 Medicare Advantage and Part D plans, the Fee-for-Service Medicare premiums and cost-sharing information released today will enable people with Medicare to understand their Medicare coverage options for the year ahead. Medicare health and drug plan costs and covered benefits can change from year to year, so people with Medicare should look at their coverage choices annually and decide on the options that best meet their health needs.

To help with their Medicare costs, low-income seniors and adults with disabilities may qualify to receive financial assistance from the Medicare Savings Programs (MSPs). The MSPs help millions of Americans access high-quality health care at a reduced cost, yet only about half of eligible people are enrolled. The MSPs help pay Medicare premiums and may also pay Medicare deductibles, coinsurance, and copayments for those who meet the conditions of eligibility. Enrolling in an MSP offers relief from these Medicare costs, allowing people to spend that money on other vital needs, including food, housing, or transportation.

Medicare Part B Income-Related Monthly Adjustment Amounts

Since 2007, a beneficiary’s Part B monthly premium is based on his or her income. These income-related monthly adjustment amounts affect roughly 7 percent of people with Medicare Part B. The 2023 Part B total premiums for high-income beneficiaries with full Part B coverage are shown in the following table:
