About 20.8 million people on Original Medicare Part B are getting a one-time $90 rebate this month, and the Centers for Medicare & Medicaid Services says people enrolled in Medicare Advantage do not qualify. CMS states the payment in one line: “Eligible beneficiaries will receive one $90 rebate in October 2026.”
The money comes from what CMS calls the Medicare Improvement Fund. The agency’s rebate FAQ, dated October 3, says “the best way to improve Medicare is to put healthcare dollars back where they belong.” The $90 is a flat amount per person, not a cap and not an average, and it is labeled as a payment to offset the October premium.
The first thing a reader needs to know is which kind of Medicare they have. Original Medicare is the government-run program, and Part B is the piece that covers doctor visits and outpatient care. People in that program are the group the rebate is built for. People in a private Medicare Advantage plan are left out, and so are people who get Medicaid help with the Part B premium or who pay the income-related surcharge known as IRMAA. Anyone unsure which group they fall in can call 1-800-MEDICARE, the number CMS lists for eligibility questions.

How the $90 reaches people
Most of the money moves by direct deposit. According to CMS’s rebate FAQ, most eligible people get a deposit from the Social Security Administration, with payments going out on or around October 8. A message from the President, by email or letter, follows in mid-October.
People without direct deposit get a paper check mailed to the address Medicare has on file, and CMS says those checks arrive later in October. A Treasury check carries the line “Medicare Improvement Fund Payment; $90 Payment to Offset October Premium.” Anyone still waiting on a check is now in the last days of the month CMS named. The FAQ does not say how a direct deposit will be labeled on a bank statement, so the printed Treasury message applies only to checks.
The rebate comes as its own deposit or check. CMS does not describe it as a credit on a premium bill or as a change to the Social Security payment, so it should not be confused with the monthly Part B premium that is already taken out of benefits.
Social Security is only the delivery route. The program belongs to CMS, which is why questions about eligibility go to Medicare while questions about where the money is go to Social Security.
The Medicare Improvement Fund dates to Section 7002 of the Supplemental Appropriations Act of 2008, which set it aside for improvements to the fee-for-service program under Parts A and B. CMS’s FAQ says Congress has drawn from it about 20 times to offset other spending, including $20.7 billion in 2010 toward the Affordable Care Act.
Who the $90 skips
The 20.8 million figure counts a narrower group than everyone who pays a Part B premium. CMS counts people in Original Medicare Part B who live in the United States, do not receive Medicaid premium assistance and do not pay IRMAA. CMS lists four groups as not eligible:
- People enrolled in Medicare Advantage
- People receiving Medicaid premium assistance
- People who pay IRMAA, the income-related monthly adjustment amount
- People who do not live in the United States
The fourth group is people who live outside the United States. CMS requires that an eligible person live in the country.
People who pay IRMAA are higher-income enrollees whose Part B premium is above the standard amount. People who get Medicaid premium assistance have a state program covering all or part of that premium. Neither group gets the $90.
The Medicare Advantage exclusion is the one with the widest reach. A person can hold a Medicare card, pay the Part B premium and still be shut out if a private plan administers their coverage. The FAQ treats the plan type, not the premium, as the dividing line.
Half of Medicare sits outside the group
Medicare Advantage now covers 34 million people, about 47.4 percent of everyone on Medicare, according to CMS’s 2027 plan announcement. That puts close to half of Medicare outside the rebate group before any other exclusion is counted.
The same announcement says Medicare’s annual open enrollment period for 2027 plans ends December 7. Plan changes made then apply to next year. The rebate itself is described as a single October 2026 payment.
Checking on a payment
Two phone numbers matter. Social Security’s payment status line, 1-800-772-1213, has been taking calls on the rebate since October 15, CMS says. Questions about whether someone is eligible go to 1-800-MEDICARE, which is 1-800-633-4227.
People who expected a deposit around October 8 and do not see one can start with the status line. People who get Medicaid premium help or pay IRMAA should expect nothing, since CMS lists both groups as not eligible. CMS has named no payment date later than October. For the 34 million in Medicare Advantage, the FAQ lists no rebate of any kind, which leaves the ordinary monthly costs of Medicare as the open question for them.
Skipped by the $90 rebate?
The $90 is a single payment, and the people it skips still face the same premium and drug bills as everyone else on Medicare. The ongoing question is what pays those bills the rest of the year, and for anyone on a limited income the answer is often a state program.
The Medicare Cost & Coverage Protection Kit is built for that second job. It lays out the new Part D out-of-pocket cap and the programs that help pay Medicare premiums and drug bills, with 51 state Medicare cost-help packs so the reader can find their own state’s route.
The kit runs five parts, from capping drug costs to beating a denial, and it comes with a medication and cost tracker for keeping the numbers in one place.
