What changed in Medicare costs for 2025

Medicare Part B premiums rose to $185 per month for most people in 2025, up from $174.70 in 2024. Part D (prescription drug coverage) premiums also increased, though the exact amount depends on which plan you chose — some plans went up by a few dollars, others by $20 or more. Part A (hospital insurance) has no monthly premium for most people, but the deductible you pay when you are admitted to the hospital went up to $1,676 for each benefit period in 2025.

These increases happen every year because Medicare costs rise with healthcare inflation and the number of people using the program. The Social Security Administration announced the Part B increase in October 2024, and your new premium took effect in January 2025. If you did not see the change on your January statement, contact Medicare directly to confirm your account was updated.

  • Part B premiums increased to $185 per month in 2025, a $10.30 jump from 2024.
  • Part D prescription drug plan premiums vary by plan and insurer, so comparing your current plan to others may save you money.
  • The Part A hospital deductible rose to $1,676 per benefit period, meaning you pay this amount out of pocket before Medicare covers hospital stays.

Part B premium increases and who pays them

The standard Part B premium for 2025 is $185 per month. This covers doctor visits, outpatient care, and some preventive services. If you are already receiving Social Security, the premium is deducted automatically from your benefit check. If you are not yet on Social Security, you receive a bill from Medicare each month.

Some people pay a higher Part B premium based on income — this is called Income-Related Monthly Adjustment Amount (IRMAA). If your modified adjusted gross income from two years ago was above a certain threshold, you pay more. For 2025, those thresholds start at $103,000 for single filers and $206,000 for married couples filing jointly. The higher premiums can range from $259 to $560 per month depending on your income bracket.

If you believe your income has dropped since the threshold was set (due to retirement, job loss, or a major life change), you can request a life-event exemption from the IRMAA increase. Contact Social Security to file this request — you will need to show proof of the change.

Part D prescription drug plan costs for 2025

Part D premiums vary widely because they are set by private insurance companies, not by Medicare. Your current plan's premium for 2025 depends on which insurer you chose and which specific plan. Some plans increased by $2 to $5, while others went up by $15 to $25 or more. A few plans even lowered their premiums.

You can see what your plan's 2025 premium will be by logging into Medicare.gov and viewing your plan details, or by calling your plan directly. If the increase is steep or if your medications are no longer covered at the same cost-sharing level, you have the right to switch plans during the annual enrollment period (October 15 to December 7). Switching plans does not affect your other Medicare coverage and carries no penalty.

Part D also includes an out-of-pocket spending cap. In 2025, once you and your plan have spent $8,550 on covered drugs, you move into catastrophic coverage and pay only a small copay for the rest of the year. This cap protects you from unlimited drug costs.

Part A hospital deductible and coinsurance

Part A covers hospital stays, skilled nursing facility care, hospice, and some home health services. There is no monthly premium for most people, but you pay a deductible when you use these services. For 2025, the Part A deductible is $1,676 per benefit period — meaning each time you are admitted to the hospital, you pay this amount before Medicare begins to cover your stay.

After you meet the deductible, Medicare covers your hospital stay fully for the first 60 days. From day 61 to day 90, you pay $419 per day (called coinsurance). If you stay longer than 90 days, you can use your lifetime reserve days — 60 additional days that Medicare will cover if you pay $838 per day. Once your lifetime reserve days are used, you pay all costs yourself.

These costs explore to each separate benefit period. A new benefit period begins when you have been out of the hospital or skilled nursing facility for 60 days in a row.

How to review your Medicare costs and plan options

Start by checking your current plan's 2025 costs on Medicare.gov. Log in with your Medicare account, go to "My Health Plans," and select your plan to see the new premium, deductible, and copay amounts. You can also call 1-800-MEDICARE to request this information by phone.

If your costs have gone up significantly, use the Medicare Plan Finder tool on Medicare.gov to compare other plans available in your area. Enter your zip code, current medications, and preferred doctors to see which plans cover your needs at the lowest cost. Many people find that switching plans saves them $100 to $300 per year, especially if their medication needs have changed.

If you are on a limited income, you may be able to get help paying your premiums and cost-sharing through the Medicare Savings Programs or Low-Income Subsidy (LIS) for Part D. These programs are run by your state, and may be able to access depends on your income and resources. Contact your state Medicaid office or call 1-800-MEDICARE to learn whether you may have access to.

What to do if you cannot afford the increases

If the premium increase puts a strain on your budget, you have several options. First, check whether you may have access to for a Medicare Savings Program in your state — these programs pay your Part B premium, deductible, and coinsurance if your income is low enough. Income limits vary by state, but generally range from about $1,500 to $2,000 per month for a single person.

Second, review your Part D plan during the annual enrollment period. Switching to a plan with a lower premium or better coverage for your specific drugs can offset the increase. Some plans also offer $0 premiums if you are willing to pay higher copays at the pharmacy.

Third, talk to your doctor about generic alternatives to expensive brand-name drugs. Generics are usually much cheaper and work the same way. Your doctor or pharmacist can tell you which medications have generic versions available.
