BALTIMORE, Maryland—The Centers for Medicare and Medicaid Services (CMS) released its 2025 premiums, deductibles and coinsurance amounts for the Medicare Part A and Part B programs, as well as its 2025 Medicare Part D income-related monthly adjustment amounts.
CMS’ 2025 updates to Medicare Parts A, B and D amounts are listed below.
Medicare Part B Premium & Deductible
Medicare Part B covers physicians’ services, outpatient hospital services, certain home health services, durable medical equipment (DME) and certain other medical and health services that are not covered by Medicare Part A.
CMS said that each year, the Medicare Part B premium, deductible and coinsurance rates are determined according to provisions of the Social Security Act. For 2025, CMS has decided the standard monthly premium for Medicare Part B enrollees will be $185.00, which is an increase of $10.30 from $174.70 in 2024. Additionally, the 2025 annual deductible for all Medicare Part B beneficiaries will be $257, which is an increase of $17 from the annual deductible of $240 in 2024.
The increase in the 2025 Part B standard premium and deductible is due to projected price changes and assumed utilization increases that are consistent with historical experience, CMS said.
As of Jan. 2023, individuals whose full Medicare coverage ended 36 months after a kidney transplant—and who do not have certain other types of insurance coverage—can elect to continue Part B coverage of immunosuppressive drugs by paying a premium. During 2025, the standard immunosuppressive drug premium will be $110.40.
Medicare Part B Income-Related Monthly Adjustment Amounts
Since 2007, a beneficiary’s Part B monthly premium has been based on his or her income. According to CMS, these income-related monthly adjustment amounts affect roughly 8% of people with Medicare Part B. Information on the 2025 Part B total premiums for high-income beneficiaries with full Part B coverage and for beneficiaries who have immunosuppressive drug coverage can be found on the full fact sheet.
Medicare Part A Premium & Deductible
Medicare Part A covers inpatient hospitals, skilled nursing facilities, hospice, inpatient rehabilitation and some home health care services. About 99% of Medicare beneficiaries do not have a Part A premium, since they have at least 40 quarters of Medicare-covered employment, as determined by the Social Security Administration.
In 2025, CMS has decided the Medicare Part A inpatient hospital deductible that beneficiaries pay if admitted to the hospital will be $1,676, which is an increase of $44 from $1,632 in 2024. Additionally, Part A inpatient hospital deductibles will cover beneficiaries’ share of costs for the first 60 days of Medicare-covered inpatient hospital care in a benefit period. CMS stated that in 2025, beneficiaries must pay a coinsurance amount of $419 per day for the 61st through 90th days of hospitalization ($408 in 2024) in a benefit period, and pay $838 per day for lifetime reserve days ($816 in 2024). For beneficiaries in skilled nursing facilities, the daily coinsurance for days 21 through 100 of extended care services in a benefit period will be $209.50 in 2025 ($204.00 in 2024).
Currently, enrollees ages 65 and older who have fewer than 40 quarters of coverage—and certain persons with disabilities—pay a monthly premium in order to voluntarily enroll in Medicare Part A. In 2025, individuals who had at least 30 quarters of coverage, or were married to someone with at least 30 quarters of coverage, may buy into Part A at a reduced monthly premium rate of $285, which is a $7 increase from 2024. Additionally, certain uninsured aged individuals who have fewer than 30 quarters of coverage—and certain individuals with disabilities who have exhausted other entitlements—will have to pay the full premium of $518 a month in 2025, which is a $13 increase from 2024.
Medicare Part D Income-Related Monthly Adjustment Amounts
Since 2011, a beneficiary’s Part D monthly premium has been based on his or her income. According to CMS, approximately 8% of people with Medicare Part D pay these income-related monthly adjustment amounts. In 2025, these individuals will have to pay the income-related monthly adjustment amount in addition to their Part D premium. Part D premiums vary by plan and, regardless of how a beneficiary pays their Part D premium, the Part D income-related monthly adjustment amounts are deducted from Social Security benefit checks or paid directly to Medicare. CMS said roughly two-thirds of beneficiaries pay premiums directly to the plan, while the remainder have their premiums deducted from their Social Security benefit checks.
