Medicare Part B Premium and Deductible Increase in 2024

The Centers for Medicare & Medicaid Services (CMS) has announced that the standard monthly Part B premium will be $174.70 in 2024, an increase of $9.80 from $164.90 in 2023. The annual deductible for all Medicare Part B enrollees in 2024 will be $240, an increase of $14 from the 2023 deductible of $226. The increases are mainly due to projected increases in healthcare spending.

Premiums and Coverage

Certain beneficiaries will continue to pay higher premiums based on their modified adjusted gross income. The monthly Part B premium that includes an income-related adjustment for 2024 will range from $244.60 to $594.00, depending on the extent to which an individual beneficiary’s modified adjusted gross income exceeds $103,000 (or $206,000 for a married couple). The highest rate applies to beneficiaries whose incomes exceed $500,000 (or $750,000 for a married couple). CMS estimates that about 8 percent of Medicare beneficiaries pay the income-adjusted premiums.

Beneficiaries in Medicare Part D prescription drug coverage plans pay premiums that vary from plan to plan. Part D beneficiaries whose modified adjusted gross income exceeds the same income thresholds that apply to Part B premiums also pay a monthly adjustment amount. In 2024, the adjustment amount ranges from $12.90 to $81.00.

The Railroad Retirement Board withholds Part B premiums, Part B income-related adjustments, and Part D income-related adjustments from benefit payments it processes. The agency can also withhold Part C and D premiums from benefit payments if an individual submits a request to his or her Part C or D insurance plan.

Tables and Adjustments

The following tables show the income-related Part B premium adjustments for 2024. The Social Security Administration (SSA) is responsible for all income-related monthly adjustment amount determinations. To make the determinations, SSA uses the most recent tax return information available from the Internal Revenue Service. That will usually be the beneficiary’s 2022 tax return information for 2024. If that information is not available, SSA will use information from the 2021 tax return.

Railroad retirement and social security Medicare beneficiaries affected by the 2024 income-related premiums will receive a notice from SSA by the end of the year. The notice will include an explanation of the circumstances when a beneficiary may request a new determination. Persons who have questions or would like to request a new determination should contact SSA after receiving their notice.
