Medicare Costs in 2026: Everything You Need to Know

Medicare is not free. While Part A hospital insurance is premium-free for most beneficiaries, Part B medical insurance, Part D prescription drug coverage, and supplemental plans all carry monthly premiums and cost-sharing requirements. Understanding how these costs work together is essential for planning healthcare spending in retirement.

Key Medicare Costs for 2026

In 2026, the standard Part B premium is $202.90 per month. The Part A deductible — which applies each time you're admitted to a hospital — is $1,736 per benefit period. For Part B, the annual deductible is $257. After meeting these deductibles, Medicare typically covers 80% of approved services while you pay 20% coinsurance.

Higher-income beneficiaries may pay more through Income-Related Monthly Adjustment Amounts (IRMAA), which apply surcharges to both Part B and Part D premiums based on your modified adjusted gross income from two years prior.

How Medicare Cost-Sharing Works

Unlike most private health insurance, Original Medicare has no annual out-of-pocket maximum. This means your 20% coinsurance responsibility has no cap — which is one of the primary reasons many beneficiaries purchase Medigap supplemental insurance or enroll in Medicare Advantage plans that include out-of-pocket limits.

Part D Prescription Drug Costs

The Inflation Reduction Act introduced a $2,000 annual out-of-pocket cap on Part D drug costs starting in 2025, now adjusted to $2,100 for 2026. This is a significant change that eliminates the coverage gap ("donut hole") and protects beneficiaries from catastrophic prescription costs. Learn more in our Part D coverage guide.
