What's Changing in Medicare for 2026

Medicare makes changes to its programs each year, and 2026 brings several significant shifts that people with Medicare should understand. These changes affect how much people pay for coverage, which services are covered, and how prescription drug costs work. Learning about these changes helps people make informed decisions about their healthcare coverage.

One major change involves adjustments to monthly premiums and deductibles across all Medicare parts. The Centers for Medicare & Medicaid Services (CMS) announces these amounts each year based on healthcare costs and program funding. In 2026, these amounts will be different from 2025, meaning people with Medicare may pay more or less depending on their specific coverage type.

The prescription drug program, known as Part D, continues to evolve in 2026. Changes include modifications to how the coverage gap (sometimes called the "donut hole") works and adjustments to cost-sharing amounts. These changes affect how much people pay out-of-pocket for medications throughout the year.

Medicare Advantage plans, also called Part C, may offer different benefits, provider networks, and costs in 2026 compared to previous years. Insurers can change their plan designs, so a plan someone has in 2025 might look different in 2026, or plans may be discontinued entirely.

Additionally, there may be new rules about telehealth services, mental health coverage, and how certain preventive services are offered. These changes reflect ongoing efforts to make healthcare more accessible and affordable for older adults and people with disabilities.

Practical Takeaway: People with Medicare should plan to review their coverage options during the annual enrollment period rather than assuming their current plan will work the same way in 2026. Setting aside time to understand what's changing allows for better decision-making about healthcare coverage.

Understanding Premium Changes for 2026

Premiums are the monthly amounts people pay to maintain their Medicare coverage. In 2026, these amounts will change, though the exact figures depend on which Medicare part someone uses. For those who receive Social Security, premium changes may be offset through a system called the "hold harmless" provision, which protects some beneficiaries from large premium increases.

Part B, which covers doctor visits and outpatient services, has a standard premium amount set each year. The 2026 premium amount was announced by CMS and represents either an increase or decrease from 2025, depending on projected healthcare costs. Most people pay this premium monthly, though some with higher incomes pay higher amounts.

Part D premiums, which cover prescription drugs, vary significantly based on which plan someone chooses. Different insurance companies offer different Part D plans with different premiums, drug formularies, and coverage structures. In 2026, some plans may increase premiums while others decrease them, making plan comparison important during enrollment.

Medicare Advantage plans set their own premiums, which can be as low as zero dollars per month, though many plans charge monthly premiums on top of the Part B premium. Some Medicare Advantage plans may raise their premiums in 2026 while others lower them. Premium changes often come with changes to what the plan covers and which doctors are in the network.

Supplemental insurance, also called Medigap, is separate from Medicare itself. Insurance companies offering Medigap plans set their own premium increases. Someone with a Medigap plan in 2025 should expect a different premium in 2026, though the exact increase varies by plan and insurance company.

Practical Takeaway: Before the annual enrollment period ends, review the premium amounts for all plans being considered. A plan with a lower premium isn't necessarily the best choice if it covers fewer services or has higher deductibles and copayments. Comparing total expected costs, not just premiums, provides better clarity on affordability.

Deductible and Copayment Updates for 2026

Beyond premiums, deductibles and copayments are also changing in 2026. These are the actual out-of-pocket costs people pay when they receive healthcare services. Understanding how these amounts change helps people budget for healthcare expenses throughout the year.

Part A covers hospital stays and includes a deductible amount that resets each benefit period. In 2026, this deductible amount will change from the 2025 amount. People who anticipate hospital care should know this deductible amount so they understand what they might owe if admitted. The deductible applies to the first days of a hospital stay, while longer stays may involve different cost-sharing arrangements.

Part B also has a deductible, which is the amount a person must pay for covered services before Medicare starts paying its share. Once someone meets the Part B deductible in 2026, they typically pay 20 percent of the cost of most doctor services and outpatient care, while Medicare pays 80 percent. The specific deductible amount for 2026 differs from previous years.

Part D uses a different cost-sharing structure that changes throughout the year. People typically pay a copayment or coinsurance for each prescription filled until they reach an out-of-pocket spending threshold. In 2026, these copayment amounts, the spending threshold, and the coverage gap details may all shift. Someone taking multiple medications should calculate expected costs based on their specific prescriptions and the plans being considered.

Medicare Advantage plans set their own deductibles and copayments, which can vary significantly from Original Medicare. Some plans have zero deductibles, while others have deductibles for certain services. Copayments for doctor visits, specialist visits, and emergency room care differ between plans and can change annually.

Practical Takeaway: Make a list of regularly used healthcare services and medications, then look up copayment and deductible amounts for each plan being considered. This creates a realistic estimate of total out-of-pocket costs for the year, not just premium costs. Plans with the same premium can have very different actual costs depending on deductibles and copayments.

Prescription Drug Coverage Changes in 2026

The Part D prescription drug program includes several design elements that change each year. In 2026, the way the program structures drug costs and coverage will shift in ways that affect how much people pay for medications throughout the year.

The coverage gap, often called the "donut hole," is a range of drug spending where beneficiaries pay a higher percentage of medication costs. Once someone spends a certain amount on covered drugs during 2026, they enter the coverage gap. The exact spending threshold and the cost-sharing percentage during the gap may change from 2025. Eventually, spending reaches a catastrophic threshold, after which the plan pays most drug costs and the person pays only a small copayment.

In recent years, there have been policy changes requiring plans to cover insulin at lower costs during the coverage gap. These insulin copayment limits may continue or change in 2026. Additionally, there have been discussions about expanding drug price negotiation through Medicare, which could affect which drugs are covered and at what costs.

The formulary, which is the list of drugs covered by a Part D plan, changes annually. A medication someone takes in 2025 might be removed from their plan's formulary in 2026, or it might move to a different cost tier with higher copayments. Insurance companies must notify people if their drugs are being removed, but it's important to verify coverage before the year begins.

People taking expensive medications should compare plans carefully based on actual drug costs, not just premium amounts. The lowest-premium plan may not cover someone's specific medications, or may require prior authorization or step therapy before paying for certain drugs. Calculating estimated annual drug costs for each plan being considered shows which plan truly offers the best value.

Practical Takeaway: Use the Medicare Plan Finder tool on Medicare.gov to look up specific medications and compare out-of-pocket costs across different Part D plans. Enter all regularly taken medications to see copayment amounts, any coverage restrictions, and total estimated costs. This takes time but reveals which plan actually costs less for an individual's specific medication needs.

Medicare Advantage Plan Changes and Considerations

Medicare Advantage plans are offered by private insurance companies and bundle Part A, Part B, and usually Part D coverage into one plan. These plans often include additional benefits that Original Medicare doesn't cover, such as dental, vision, or fitness benefits. In 2026, plan options, benefits, and networks will change, sometimes significantly.
