If you are enrolled in Medicare, it’s important to understand how your premiums, deductibles, and out-of-pocket costs will change in 2026. The new year brings increases in some areas and slight decreases in others, depending on the type of coverage you have and your income.

Knowing what to expect can help you plan your healthcare budget and make informed decisions about your coverage options.

Medicare Premiums and Deductibles Are Rising

Medicare Part B premiums are set to increase by roughly 9.7% in 2026. This is one of the larger annual increases in recent years and will affect the monthly premium many beneficiaries pay for doctor visits, outpatient care, and certain preventive services. Meanwhile, the Part A deductible, which applies to inpatient hospital care, is rising by 3.7%—a smaller but still meaningful increase.

These changes mean that understanding the full scope of your Medicare costs—beyond just the monthly premium—is crucial. Deductibles, coinsurance, and income-related surcharges all play a role in the total amount you could pay for medical care throughout the year.

For individuals with higher incomes, additional costs may be applied in the form of the Income-Related Monthly Adjustment Amount (IRMAA). The IRMAA affects both Part B and Part D premiums, meaning that high earners could see a notable increase in monthly payments.

In 2026, the Part B IRMAA ranges from $81.20 to $487.00 per month, while the Part D IRMAA ranges from $14.50 to $91.00. The actual amount depends on your income from two years prior, so your 2024 adjusted gross income determines your 2026 surcharge.
