The Centers for Medicare & Medicaid Services says 20.8 million Americans enrolled in Original Medicare Part B are eligible for the rebate. Most qualifying beneficiaries with direct deposit should receive the money on or around Oct. 8, while paper checks will arrive later in October. No application is required.
The payment is intended to offset part of October’s Medicare Part B premium, which stands at $202.90 per month in 2026. That means the rebate covers roughly 44% of one standard monthly premium.
Who Qualifies for the $90 Medicare Payment?
Eligibility is narrower than simply being enrolled in Medicare.
CMS says recipients must be enrolled in Original Medicare Part B, live in the United States, not receive Medicaid assistance paying their Part B premium, and not pay an Income-Related Monthly Adjustment Amount, or IRMAA.
That leaves four major groups outside the program: Medicare Advantage members, higher-income beneficiaries paying IRMAA, people receiving Part B premium assistance through Medicaid or a Medicare Savings Program, and beneficiaries living outside the U.S.
The Medicare Advantage exclusion is particularly large. Roughly 35 million people are enrolled in private Medicare Advantage plans, even though many still pay Part B premiums.
That comes as Medicare Advantage plans are undergoing their own pricing and network changes heading into 2027.
Payments Are Automatic
Eligible beneficiaries do not need to register or submit a claim.
Most payments will arrive through the same direct-deposit details used by the Social Security Administration. People without direct deposit will receive a Treasury check at the mailing address registered with Medicare. CMS says those checks will carry the description “Medicare Improvement Fund Payment.”
Anyone unsure about eligibility can call 1-800-MEDICARE, while payment-status questions can be directed to Social Security beginning Oct. 15.
The rebate follows separate $500 refunds being distributed to some Affordable Care Act enrollees.
$90 May Be Quickly Absorbed by Rising Costs
The payments will come from the Medicare Improvement Fund, which currently contains just over $2 billion. KFF estimates the rebate program will consume most of the fund.
The bigger issue is what happens next.
KFF estimates standard Part B premiums could increase by about $79 annually in 2027, meaning most of the one-time $90 rebate could effectively be offset by next year’s higher premiums alone. Other costs, including Part D premiums, deductibles and Medigap coverage could rise as well.
Those increases will also interact with the upcoming Social Security COLA, which determines how much monthly retirement benefits rise next year.
