2025 Medicare Changes to Part B and Part D Premiums, Part A Deductibles, and IRMAA

The Centers for Medicare and Medicaid (CMS) has released the changes to Medicare premiums, deductibles, and income adjustments for 2025.

Medicare Part B Premiums and IRMAA for 2025

Medicare Part B is essential for medical coverage, and its standard monthly premium in 2025 is $185.00, a little over ten dollars more than the standard premium in 2024. However, if you reported more than $106,000 in modified adjusted gross income (MAGI) on your 2023 tax return (or $212,00 for joint filers), you will pay a higher premium. This added charge is known as the Income-Related Monthly Adjustment Amount (IRMAA). The Social Security Administration determines IRMAA based on your tax return, and if applicable, you will receive an IRMAA letter notifying you of the increased premium amount. The annual deductible for Part B beneficiaries is $257 in 2025, about $17 more than in 2024.

Medicare Part A deductible and coinsurance changes in 2025

In 2025, if a beneficiary stays at a hospital 1-60 days, the deductible is set at $1,676 ($44 more than in 2024). If the inpatient stay is longer than 60 days, the beneficiary must pay a daily coinsurance of $419 from the 61st-90th day.
