Why didn't I get the $90 Medicare Part B rebate?
The $90 Part B premium rebate is a one-time October 2026 payment for some people in Original Medicare. Who qualifies, when it arrives, how to check.

The short answer
The $90 Part B premium rebate, which CMS calls the Medicare Improvement Fund Premium Rebate, is a one-time payment going out in October 2026. According to CMS, it goes to people in Original Medicare Part B who:
- live in the United States,
- don’t get help from Medicaid paying their Part B premium (in California, Medicaid is Medi-Cal), and
- don’t pay an Income-Related Monthly Adjustment Amount (IRMAA), the extra Part B charge for higher incomes.
CMS says people enrolled in Medicare Advantage are not eligible.
If you do qualify, CMS says most people get a direct deposit on or around October 8, 2026. Some people get a paper check later in October. If you haven’t seen it yet, it may still be on its way.
This page is educational. It’s based on CMS’s published FAQ and doesn’t make any guess about future payments.
What are the most common reasons people don’t get the $90?
| Your situation | Do you get the $90? | Why |
|---|---|---|
| You’re in a Medicare Advantage plan (Part C) | No | CMS says Medicare Advantage enrollees aren’t eligible |
| Medi-Cal (Medicaid) helps pay your Part B premium | No | CMS limits the rebate to people not getting Medicaid premium help |
| You pay IRMAA (a higher Part B premium because of income) | No | CMS excludes people who pay IRMAA |
| You live outside the United States | No | CMS limits the rebate to people living in the U.S. |
| You don’t have Part B | No | It’s a Part B premium rebate for people in Original Medicare Part B |
| You qualify but don’t have direct deposit | Yes, by check | CMS says people without direct deposit get a check mailed to the address Medicare has on file, later in October |
| You qualify and it’s early October | Probably soon | Most direct deposits are scheduled for on or around October 8 |
What should I check if I think I qualify?
- The date. CMS says most direct deposits arrive on or around October 8, 2026, and paper checks come later in October.
- Your type of coverage. The rebate is for Original Medicare Part B. If you’re in a Medicare Advantage plan, your plan’s member materials will say so.
- Who pays your Part B premium. If Medi-Cal pays it for you, CMS says you aren’t eligible.
- Whether you pay IRMAA. The Social Security Administration sends a letter to people who must pay this income-related amount. If you got one for 2026, CMS says you aren’t eligible.
- Your mailing address. If you don’t have direct deposit, CMS says the check goes to the address Medicare has on file.
- The payment-status date. CMS says payment-status questions go to the Social Security Administration starting October 15, 2026.
When does the $90 rebate arrive?
| What | When (per CMS) | From |
|---|---|---|
| Direct deposit (most people) | On or around October 8, 2026 | Social Security Administration |
| Email or letter about the rebate | Mid-October 2026 | Sent after the direct deposit |
| Paper check (some people) | Later in October 2026 | U.S. Department of the Treasury |
CMS says the paper check comes with this message: “Medicare Improvement Fund Payment; $90 Payment to Offset October Premium.”
If you qualify and don’t have direct deposit, CMS says the check goes to the mailing address you have registered with Medicare.
How do I check whether I’m eligible or where my payment is?
CMS sends eligibility questions and payment-status questions to different places:
- Eligibility: CMS’s Medicare Improvement Fund Premium Rebate FAQ lists who qualifies and how to check. Read it first.
- Payment status: the same CMS FAQ says payment-status questions go to the Social Security Administration starting October 15, 2026. The direct deposits also come from the Social Security Administration.
If you’re waiting on a check, make sure Medicare has your current mailing address. CMS says checks go to the address you have registered with Medicare.
Is the $90 rebate a monthly payment?
No. CMS describes it as one $90 rebate in October 2026. CMS hasn’t announced any more payments, so don’t plan around getting another one.
I’m in a Medicare Advantage plan. Should I change coverage to get the $90?
Changing coverage won’t get you this rebate. It’s a single payment tied to October 2026. Coverage changes made during Open Enrollment (October 15 to December 7, 2026) take effect January 1, 2027, which is after the rebate goes out.
Choose your 2027 coverage on what matters for your care: your doctors, prescriptions, costs, and what’s offered in your county.
Do I need to apply for the $90?
CMS doesn’t describe any application. It says the rebate goes out by direct deposit from the Social Security Administration, or by check to the address Medicare has on file.
If someone contacts you out of the blue and asks for your Medicare Number, bank details, or a fee to “release” the $90, treat it as a red flag. Don’t share that information with someone who contacted you first.
Where does the money come from?
CMS says the rebate is paid from the Medicare Improvement Fund, which Congress created in Section 7002 of the Supplemental Appropriations Act of 2008.
