Eligible Original Medicare Part B beneficiaries are scheduled to receive a one-time $90 rebate in October 2026. To qualify, you must live in the United States, receive Original Medicare Part B, and not receive Medicaid premium assistance or pay an income-related monthly adjustment amount (IRMAA). People enrolled in Medicare Advantage are excluded.
Who qualifies for the $90 Medicare rebate?
The Centers for Medicare & Medicaid Services (CMS) says the rebate is intended for 20.8 million U.S. residents enrolled in Original Medicare Part B. That figure is the agency’s estimate of the eligible population, not a count of payments already delivered.
You must meet all of these conditions:
- You live in the United States.
- You have Original Medicare Part B.
- You do not receive Medicaid premium assistance.
- You do not pay IRMAA, the income-related monthly adjustment amount added to Medicare Part B premiums for some beneficiaries.
Medicare Advantage enrollees are not eligible. Having Medicare coverage alone does not qualify someone: the type of coverage and whether they receive premium assistance or pay IRMAA matter. See CMS’s October 3, 2026 FAQ for the agency’s eligibility details.
When and how will the rebate arrive?
CMS says eligible beneficiaries will receive one $90 rebate in October 2026. Most are expected to receive a direct deposit on or around October 8, 2026, followed by an email or letter from the President in mid-October. The deposit is sent through the Social Security Administration (SSA).
Some beneficiaries will instead receive a paper check from the U.S. Department of the Treasury later in October. CMS says checks will be mailed to the address registered with Medicare. The check message is “Medicare Improvement Fund Payment; $90 Payment to Offset October Premium.”
Is this a permanent reduction in the Part B premium?
No. CMS describes this as a one-time rebate to offset the October 2026 Part B premium, not an ongoing reduction in the monthly premium. The Medicare Improvement Fund was created by section 7002 of the Supplemental Appropriations Act of 2008 to support improvements under Original Medicare Parts A and B. The White House says Congress provided $2 billion to the fund for improvements to Medicare fee-for-service.
