Medicare 2026: CMS Finalizes New Part B Costs, Payment Reforms, and Early Medicare Advantage Changes

Medicare beneficiaries are heading into 2026 with several new updates from the Centers for Medicare & Medicaid Services (CMS). While year-to-year changes are common, this year's set of adjustments is especially important because it affects not only what you pay, but also how Medicare evaluates and reimburses physicians and health plans.

Below is a clear, easy-to-follow explanation of what's changing, why it matters, and what older adults should be paying attention to over the next few months.

Part B Premiums and Deductibles Are Increasing for 2026

CMS has finalized the 2026 standard Part B premium at $202.90, an increase from $185.00 in 2025. For many seniors living on a fixed income, even moderate increases can impact monthly budgeting.

Along with the premium increase, the annual Part B deductible will rise from $257 to $283. This means beneficiaries will need to meet a slightly higher out-of-pocket amount before Medicare begins paying its share for services.

While cost increases are never welcome news, CMS notes that the premium would have been even higher had the agency not recently taken action to reduce overspending in certain medical procedures—particularly "skin substitutes," an area historically prone to misuse and inflated billing.

What These Increases Mean for You

For most beneficiaries, the rise in Part B costs will be noticeable but manageable. Still, seniors with limited income, those paying IRMAA (Income-Related Monthly Adjustment Amount), and people managing multiple chronic conditions may feel the impact more strongly.

If you receive Social Security benefits, your Medicare premium is typically deducted before the payment is deposited. Some seniors will see a slightly smaller net Social Security payment in 2026 as a result.

Now is a good time to:

• Review your fixed monthly expenses
• Check whether you may be subject to IRMAA
• Consider whether a Medicare Supplement (Medigap) plan may help stabilize unexpected costs
• Review any 2026 plan materials you've received to ensure your doctors, drugs, and benefits remain affordable

Physician Payment Reforms Take Effect January 1, 2026

CMS has also finalized updates to the Medicare Physician Fee Schedule, which determines how doctors and specialists are reimbursed. The changes aim to promote high-value care while reducing waste and fraud.

1. Reducing Overpayments for Certain Procedures — Some services that have historically been overused—particularly advanced wound-care products—will receive lower reimbursement to discourage unnecessary or inappropriate use.

2. Strengthening Preventive and Chronic Care — CMS continues to shift resources toward care that keeps people healthier over the long term. This includes diabetes management, behavioral health treatment, fall prevention, and routine preventive screenings.

3. Modernizing Payment Accuracy — CMS is updating coding, auditing processes, and documentation rules to better align reimbursement with actual clinical need and current medical practice patterns.

For beneficiaries, these changes should not limit access to medically necessary care. Instead, they are intended to encourage providers to focus on effective, evidence-based treatments.

Early Look at Proposed 2027 Medicare Advantage and Part D Changes

Although these changes would not take effect until 2027, CMS has issued a proposed rule that could reshape Medicare Advantage (MA) and Part D drug coverage in meaningful ways.

1. Updating the Star Ratings System — CMS wants to ensure its quality-rating system more accurately reflects how well plans serve beneficiaries. Changes may include recalibrated scoring methods, stronger reporting standards, and new performance measures.

2. Adjusting Drug Benefit Structures — Some elements of Part D—such as how plans share financial responsibility with CMS—may be revised to better align with the upcoming $2,000 cap on out-of-pocket drug spending.

3. Stronger Plan Oversight — CMS is proposing increased scrutiny of marketing practices, provider directory accuracy, and appeals processing. These steps are meant to protect beneficiaries from confusion, misinformation, or unexpected costs.

These proposals often lead to shifts in plan design. If finalized, beneficiaries could see changes in networks, drug tiers, or premium structures in future years.

What Beneficiaries Should Do Now

With these changes on the horizon, here's what you can do to stay ahead:

• Review your 2026 Plan Documents — If you're enrolled in Medicare Advantage or a Part D plan, check your Annual Notice of Change (ANOC) for any premium, coverage, or network adjustments
• Check Your IRMAA Status — If your income changed in the past two years (including retirement), you may be subject to different premiums—or you may be able to appeal
• Ask Questions — If you're unsure about how these changes apply to you, call 1-800-MEDICARE or contact a local SHIP counselor for free, unbiased assistance
• Stay Informed — CMS releases new information regularly. Following updates on Medicare.gov or from trusted news sources can help you plan ahead
