Medicare’s $90 Part B Rebate: Eligibility, Payment Timing, and Safe Verification

The one-time $90 Medicare Improvement Fund rebate is for eligible people living in the United States with Original Medicare Part B.
People with Medicare Advantage, Medicaid premium assistance, or an income-related monthly adjustment amount generally don’t qualify.
Most payments are sent by direct deposit, while some beneficiaries receive a U.S. Treasury check; use Medicare or Social Security directly to verify a missing payment.

What the $90 Medicare Part B rebate is

CMS says eligible beneficiaries will receive a one-time $90 Medicare Improvement Fund Premium Rebate in October 2026. The payment is intended to offset part of the October Medicare Part B premium, not to replace the regular monthly premium or create a permanent reduction.

The rebate is connected to Original Medicare Part B. It isn’t an application-based benefit, and eligible beneficiaries don’t need to buy a plan, provide banking information through a text message, or pay a fee to receive it.

For context, the standard Medicare Part B premium is $202.90 per month in 2026, although some people pay more because of IRMAA, a late-enrollment penalty, or other circumstances.

CMS says most eligible beneficiaries were scheduled to receive the payment by direct deposit around October 8, 2026. Beneficiaries who don’t have direct deposit may receive a paper check from the U.S. Department of the Treasury later in October.

Important: October 2026 timing doesn’t mean every payment arrives on exactly the same day. Bank posting times, mailing, weekends, and individual payment arrangements can affect when the money becomes visible.

Who qualifies for the $90 rebate?

According to CMS, the rebate is limited to people who meet all of the main conditions below:

You’re enrolled in Original Medicare Part B.
You live in the United States.
You don’t receive premium assistance through Medicaid.
You don’t pay an Income-Related Monthly Adjustment Amount, commonly called IRMAA.

CMS estimates that about 20.8 million people meet the stated eligibility rules. The eligibility decision is based on Medicare and Social Security records, so there’s no separate rebate application for beneficiaries to complete.

Who generally isn’t eligible?

People enrolled in Medicare Advantage aren’t eligible for this particular rebate, even though Medicare Advantage plans are required to cover Medicare Part A and Part B services. Medicare Advantage plans may have their own premium reductions or benefits, but those are separate from the CMS rebate.

You also generally won’t qualify if Medicaid or a Medicare Savings Program is paying your Part B premium. In that situation, you may already be receiving premium assistance through a different program.

People who pay IRMAA are excluded under CMS’s stated rules. IRMAA is the additional Part B amount charged to higher-income beneficiaries. A person can have Original Medicare and still be ineligible if IRMAA applies.

Situation	Likely result
Original Medicare Part B, living in the United States, no Medicaid premium assistance, no IRMAA	Generally eligible
Medicare Advantage	Not eligible for this rebate
Medicaid or Medicare Savings Program pays the Part B premium	Generally not eligible
Original Medicare Part B with IRMAA	Not eligible under CMS’s stated rules

If your situation is unusual—for example, you recently changed coverage, moved outside the United States, or had a change involving Medicaid or IRMAA—don’t rely on a message from a third party. Ask Medicare to confirm your eligibility.

How the payment arrives

There are two main delivery methods:

Direct deposit: Most eligible beneficiaries receive the $90 through the account used for their Social Security payment or another payment arrangement on file.
Paper check: Beneficiaries without direct deposit may receive a check mailed by the U.S. Department of the Treasury to the address on record.

The payment should not require you to click a link, install an app, confirm a password, or send money back. A text or email saying you must “activate” the rebate is a warning sign, particularly if it asks for your Medicare number, Social Security number, bank login, debit card details, or a processing fee.

CMS describes the Treasury check as carrying a payment message identifying the Medicare Improvement Fund and the $90 payment to offset the October premium. A check that looks suspicious should be verified through an official agency before it’s deposited or discarded.

How to check eligibility or a missing payment safely

Start with the agency that handles the question you have. Medicare is the right first contact for eligibility. Social Security is the right contact for the delivery status of a payment sent through its payment system.

Step 1: Confirm that your coverage matches the eligibility rules

Review whether you have Original Medicare Part B rather than Medicare Advantage. Then consider whether Medicaid, a Medicare Savings Program, or IRMAA applies to you.

For an official eligibility check, call 1-800-MEDICARE at 1-800-633-4227. TTY users can call 1-877-486-2048. Medicare’s representatives can help clarify whether your coverage and premium status fit the rebate rules.

Contact Medicare about the $90 rebate

Step 2: Check the account or mailbox connected to your benefits

If you normally receive Social Security or another federal benefit by direct deposit, review the account’s October transactions. Look for a separate $90 credit rather than assuming it will appear as a change to your regular monthly benefit.

If you don’t use direct deposit, check the mailing address associated with your Medicare and Social Security records. Allow reasonable mailing time during October before treating the payment as missing.

Check or update your Social Security address and direct deposit information

Step 3: Contact Social Security about delivery status

CMS says beneficiaries can contact Social Security beginning October 15, 2026, to ask about the status of a payment. Call 1-800-772-1213, Monday through Friday from 8 a.m. to 7 p.m. local time. TTY users can call 1-800-325-0778.

Use the official Social Security number even if a caller, email, or social media post gives you a different number. Don’t use a phone number supplied in an unsolicited message.

How to spot a rebate scam

Government benefit announcements often attract impersonation scams. Treat unexpected contact about the $90 payment cautiously, especially when the sender creates urgency.

Be suspicious if someone:

Promises a larger payment if you provide extra personal information.
Requests your Medicare number, Social Security number, bank password, or one-time verification code by text or email.
Asks you to pay a fee, buy a gift card, or send money to release the rebate.
Pressures you to click a link or download an attachment.
Claims your Medicare coverage will be canceled unless you act immediately.

Medicare says it will only call and request personal information in limited situations, such as returning a call or following up after a report. If you receive a suspicious message, don’t reply. Save the message or envelope, verify the payment independently, and report suspected Medicare fraud.

Report suspected Medicare fraud or a rebate scam

What to do if your payment is still missing

If you appear to meet the rules but haven’t received the rebate, use this order:

Confirm that you have Original Medicare Part B and don’t have Medicaid premium assistance or IRMAA.
Check your bank account and mailbox for a separate $90 payment.
Make sure your mailing address and payment information are current with the relevant agency.
Call Medicare to confirm eligibility.
After October 15, call Social Security to ask about payment delivery status.

Keep notes of the date you called, the agency, and any confirmation number or instructions you receive. Never give account access to someone who contacts you unexpectedly claiming to be able to “release” the payment.

For readers in Canada, this U.S. rebate doesn’t apply. The Medicare Improvement Fund Premium Rebate is a United States federal Medicare payment, not a Canadian benefit or a Canada-wide rebate.

Helpful next step

If you think you qualify and the payment hasn’t appeared, verify your eligibility with Medicare first. If Medicare confirms that you’re eligible, contact Social Security about delivery after October 15, 2026. That route is safer than responding to an unsolicited message or searching for a rebate form online.
