Medicare Premium, Deductible, and Cost-Sharing Changes for 2025
Revised on April 22, 2025
The Centers for Medicare & Medicaid Services (CMS) update Medicare premiums, deductibles, and coinsurance amounts for Part A and Part B, and the Medicare Part D income-related monthly adjustment amounts known as IRMAA annually. The 2025 changes are summarized below.
Medicare Part B Premium & Deductible
Medicare Part B covers physician’s services, outpatient hospital services, certain home health services, durable medical equipment, and certain other medical and home health services not covered by Medicare Part A. The Medicare Part B premium, deductible, and coinsurance rates are determined annually, according to provisions of the Social Security Act.
The standard monthly premium for Medicare Par B enrollees will be $185 in 2025, an increase of $10.30 from $174.70 in 2024. The annual Part B deductible will be $257 in 2025, an increase of $17 from the annual deductible of $240 in 2024.
Beginning in 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. For 2025, the standard immunosuppressive drug premium is $110.40 per month.
Medicare Part B & Part D Income-Related Monthly Adjustment Amounts known as IRMAA
If your income is over certain thresholds, Medicare charges an additional amount called “IRMAA” for Part B and Part D. “IRMAA” stands for Income Related Monthly Adjustment Amount. Below are the IRMAA amounts for 2025 for Part B and Part D. Note that Medicare looks back at your income that you reported on your tax return from 2-years prior to determine the applicable IRMAA. If IRMAA applies to you, but you had a major life-changing event and your income has gone down, you may request a reduction in your IRMAA by completing SSA Form-44.

Part A Premium
Medicare Part A is known as “hospital insurance” and covers inpatient hospital, skilled nursing facility, hospice, inpatient rehabilitation, and some healthcare services. For 99% of Medicare beneficiaries, Part A is premium-free because they have at least 40-quarters of Medicare covered employment as determined by the Social Security Administration.
For those that don’t qualify, Part A can be purchased for a monthly premium of $518 in 2025. For certain individuals who qualify, a reduced Part A premium of $285 may apply.
Part A Deductible
The Medicare Part A deductible for inpatient hospital services will be $1,676 in 2025, a $44 increase from 2024 ($1,632). This Part A deductible covers beneficiaries’ share of costs for the first 60 days of a Medicare-covered inpatient hospital stay in a benefit period. A benefit period begins when you enter the hospital and ends when you are out for 60 days in a row.
For days 61-90 of hospitalization, beneficiaries must pay a coinsurance amount of $419 per day in 2025 (up from $408 in 2024). Original Medicare covers up to 90 days of inpatient hospital care each “benefit period”. A benefit period begins the day you are admitted to a hospital as an inpatient, or to a skilled nursing facility (SNF), and ends the day you have been out of the hospital or SNF for 60 days in a row. You also have an additional 60 days of coverage, called “lifetime reserve days”. These 60 days can be used only once in your lifetime, and you will pay a coinsurance of $838 per day in 2025 (up from $816 per day in 2024). Keep in mind that many Medicare insurance plans cover this deductible and/or help pay inpatient hospital copays.
Skilled Nursing Facility Coinsurance
For beneficiaries in skilled nursing facilities the daily coinsurance of extended care services in a benefit period for days 1-20 is $0 per day daily coinsurance, but for days 21-100 it is $209.50 per day in 2025 (up from $204 in 2024). Many Medicare insurance plans help cover these coinsurance costs.
Special Enrollment Circumstances2
You can make changes to your Medicare Advantage and Medicare Part D drug coverage when certain events happen in your life, like if you move, you lose your other coverage, you are impacted by a natural disaster or other emergency, and more. These chances to make changes are called Special Enrollment Periods (SEP). The type of changes you can make and the timing depend on your life event.
Starting January 1, 2024, if you sign up for Part A and/or Part B because of an exceptional situation, you’ll have 2-months to join a Medicare Advantage plan (with or without drug coverage) or a Medicare Part D Drug plan.
If you miss an enrollment period because of certain exception circumstances, like being impacted by a natural disaster or an emergency, incarceration, or losing Medicaid coverage. Medicare has the ability to offer a special exception if you missed your enrollment window for a good reason. You’ll need to contact Medicare directly to request a special enrollment exception. For more information, visit Medicare.gov or call 1-800-MEDICARE (1-800-633-4227). TYY users can call 1-877-486-2048.
