4 questions about who gets ACA and Medicare checks

The White House says the refunds come from a surplus of ACA marketplace user fees. Its description of those fees as overcharges is the administration’s account, not an independently established finding in the reporting.

The refund does not go to everyone who buys a marketplace plan. CBS News reports that about 18 million ACA enrollees will not receive it. The public eligibility description identifies federal-marketplace enrollment and the absence of subsidies as requirements, but does not detail every step used to determine recipients.

The check is also separate from ACA premium tax credits. The enhanced premium tax credits expired in December after Congress allowed them to lapse. A one-time refund does not restore that added assistance or reduce a recipient’s future monthly premium.

Who qualifies for the $90 Medicare rebate?

The $90 payment is for eligible people with Original Medicare who live in the United States, do not receive Medicaid help paying their premiums and do not pay an income-related monthly adjustment amount, an additional premium based on income. People enrolled in Medicare Advantage are excluded. The Centers for Medicare & Medicaid Services says 20.8 million people qualify; CBS News reports that about 40 million Part B recipients will not receive the rebate.

Medicare Part B helps pay for services such as doctor visits, outpatient care and preventive screenings. CMS describes the rebate as help with Part B premiums, not payment for a particular service or a reduction in future premiums.

CMS says most eligible beneficiaries are expected to receive the money by direct deposit around Oct. 8. People without direct deposit are expected to get paper checks later in October. Those are expected delivery dates, not confirmation that payments have arrived; the available reporting does not give a final count of recipients paid.

The administration announced the rebate Friday, Oct. 2, and says it will draw on the Medicare Improvement Fund. TIME reports that Congress established the fund in 2008 to improve Original Medicare. William Dow, a health policy professor at the University of California, Berkeley, estimated that rebates could total roughly $1.9 billion, TIME reported. That is an estimate, not a confirmed final amount. TIME’s report on the Medicare rebate also notes that CMS’s FAQ does not explain the legal basis for using the fund for direct payments.

How do the payments compare with recurring premiums?

For someone paying the standard Part B premium, the monthly charge rose from $185 in 2025 to $202.90 in 2026. That is an increase of $17.90 a month, or $214.80 over a full year. The $90 rebate equals about 42% of that annual increase; it does not cover the full amount, and the higher monthly premium continues.

That comparison applies to people paying the standard premium. The rebate’s one-time value does not establish the premium increase for every individual beneficiary, and it does not turn into an ongoing discount.

ACA marketplace premiums also rose, but the available average is for a different group from the people eligible for the $500 checks. KFF found that average monthly premium payments after tax credits increased from $113 in 2025 to $178 in 2026, a rise of 58%, or $65 a month. That increase annualizes to $780, but the average after-tax-credit figure does not show how much premiums rose for the unsubsidized enrollees receiving the refund.

The distinction matters: people who received ACA subsidies are excluded from the $500 payment, while the KFF average is reported after tax credits. The $500 refund therefore cannot be presented as offsetting a typical $780 increase for its recipients. The figures describe different populations, and the refund does not lower their later monthly bills.

What do the checks leave unchanged?

Both payments are one-time. The checks are also not recurring premium support.

The eligibility rules leave out many people enrolled in the same programs. Medicare Advantage enrollees, beneficiaries who receive Medicaid premium assistance and people paying income-related Part B premiums do not qualify for the $90 rebate. The ACA refund is limited to people who used a federally administered exchange and did not receive subsidies.

Lindsay Allen, a health economist and policy researcher at Northwestern University’s Feinberg School of Medicine, told TIME that a one-time payment does not change ongoing Medicare costs. She also argued that excluding people whose premiums are paid by Medicaid leaves out some financially vulnerable beneficiaries.

For ACA enrollees, restoring the enhanced premium tax credits would address monthly costs differently from a one-time check. Brian Keyser and Natasha Murphy of the Center for American Progress argued that renewing those credits would be a more effective way to lower health costs. The payments offer short-term help to selected recipients, but they do not replace recurring assistance.

The Medicare rebate also raises a question about what the fund will support. Dow raised concern that payments could leave less money for other Medicare improvements, but the reporting does not establish whether any changes will be delayed or abandoned. CMS’s FAQ also leaves unanswered what legal authority permits the direct payments.
