Seniors facing mounting healthcare expenses just got more bad news: Medicare's standard monthly Part B premium will jump to $202.90 in 2026, marking a 9.7% increase from this year's $185 rate, the Centers for Medicare and Medicaid Services announced.

Premiums and Deductibles Both Climbing

The increase nearly doubles last year's percentage bump, when premiums rose from $174.70 in 2024 to $185 in 2025. And it's not just the monthly premium—the annual deductible for Part B enrollees will climb to $283 next year.

CMS also released the 2026 monthly actuarial rates for Part B, setting them at $405.40 for seniors and $585.60 for disabled enrollees. These figures help determine how costs get divided between beneficiaries and the federal government.

For context, Part B covers doctor visits, outpatient hospital care, ambulance services, certain prescription drugs, durable medical equipment, oxygen therapy, and substance use disorder treatment, according to the Medicare website.

The Skin Substitute Problem Nobody Saw Coming

Here's where things get interesting. According to The Hill, the Trump administration says the premium increase would have been even steeper without an aggressive push to control Part B spending on skin substitutes—biologic and synthetic products used in outpatient wound care.

In a July rulemaking, CMS proposed measures to "reduce waste and unnecessary use of skin substitutes," pointing to data showing that Part B spending on these products exploded from roughly $256 million in 2019 to more than $10 billion by 2024. That's about a 40-fold increase in five years.

A September report from the Department of Health and Human Services' Office of Inspector General warned that skin substitutes "have skyrocketed" to over $10 billion annually and "seem particularly vulnerable to questionable billing and fraud schemes," urging swift payment reforms.

Social Security Bump May Disappear

CMS explained that the 2026 increase stems "mainly from projected price changes and assumed utilization increases," but noted that without the skin-substitute crackdown, the standard premium would be about $11 higher per month.

The timing couldn't be worse for retirees. The higher premiums arrive just as Social Security benefits rise 2.8% in 2026 as part of the annual cost-of-living adjustment. Analysts already warn that once Medicare deductions are factored in, that increase may feel pretty underwhelming.
