Original Medicare Members Are Getting a One-Time $90 Part B Rebate. How to Check Yours

By Mike Harper · October 21, 2026

If you have Original Medicare, there is a good chance $90 has already landed in your bank account this month, or a check for that amount is on its way. Many people missed it because the deposit arrived with little explanation, and some may not get it at all.

The payment is a one-time rebate toward the October Part B premium. According to a question-and-answer sheet from the Centers for Medicare & Medicaid Services, it is going to about 20.8 million people in Original Medicare Part B. The money comes from the Medicare Improvement Fund, which CMS says Congress created in a 2008 spending law to improve the traditional fee-for-service program.

Who qualifies comes down to a few rules. CMS lists them this way.

You live in the United States. The rebate is for Part B enrollees living in the country.

You have Original Medicare. CMS says people enrolled in Medicare Advantage are not eligible, even though they also pay a Part B premium.

Medicaid isn’t paying your premium. If you get premium help from Medicaid, you are left out.

You don’t pay the income surcharge. People who pay the Income-Related Monthly Adjustment Amount, the extra premium charged to higher earners, do not get the rebate.

How the money arrives depends on how you get paid now. CMS says most eligible people were to receive a $90 direct deposit from the Social Security Administration on or around October 8, followed by an email or a letter from the President in mid-October. People without direct deposit are getting a paper check from the U.S. Treasury later in October, mailed to the address Medicare has on file. CMS says the check comes with this message: “Medicare Improvement Fund Payment; $90 Payment to Offset October Premium.”

Here is what to check this week.

Your bank statement. Look for a $90 deposit from around October 8. It may show up as a federal or Social Security payment rather than with the word Medicare.

Your mailbox. Medicare.gov describes the letter that goes with the rebate and says that if you get it, you should look for a direct deposit to your bank account or a check from the U.S. Treasury. If you were expecting a check and moved recently, make sure Medicare and Social Security have your current address.

Your eligibility. If you think you qualify and nothing has come, CMS says to call 1-800-MEDICARE (1-800-633-4227) to check whether you are eligible.

Your payment status. To ask where a payment is, CMS says to call Social Security at 1-800-772-1213. That line began taking these questions on October 15.

There is one more thing to keep in mind. Any time money from Medicare is in the news, scammers follow. Nothing in CMS’s description of the payments asks you to apply, pay a fee, or give anyone your Medicare number. Medicare’s own fraud guidance says Medicare will never call you to sell you anything or visit you at your home, and it urges people to protect their Medicare card and number. If someone calls about your “$90 refund” and asks for personal or bank details, hang up and call 1-800-MEDICARE yourself.
