Medicare’s $90 Part B Rebate in 2026: Who Qualifies and How to Check

Medicare is issuing a one-time $90 rebate in October 2026 to certain people with Original Medicare Part B. It is not a monthly increase and does not go to everyone who has Medicare. If you expected a payment but have not seen it, the useful first step is to distinguish an eligibility question from a payment-status question.

The Centers for Medicare & Medicaid Services (CMS) says the program is intended for about 20.8 million people. Its October 3, 2026, rebate FAQ describes the amount, who is covered and where to call.

Who is eligible for the $90 payment?

CMS identifies people living in the United States with Original Medicare Part B as the group considered for the rebate. The rules also distinguish people whose Part B premium is paid with Medicaid assistance and those who pay an income-related monthly adjustment amount (IRMAA). Medicare Advantage enrollees are excluded. The official Medicare rebate-letter page confirms that the payment is limited to certain Original Medicare Part B enrollees.

Use these examples to identify which question to ask Medicare—not as a substitute for an individual eligibility check:

• Original Medicare Part B, paying your own standard premium: You generally fit the group CMS describes if you live in the United States and do not pay IRMAA. Confirm if your circumstances are unusual.
• Medicare Advantage (Part C): CMS explicitly says these enrollees are not eligible for this payment, even though many pay a Part B premium.
• Medicaid pays your Part B premium: Premium assistance is an exclusion identified in the federal eligibility descriptions. If you are unsure who pays, ask Medicare to check your record.
• You pay IRMAA: This income-related Part B surcharge is another exclusion in the federal eligibility descriptions. See our guide to Medicare IRMAA to understand the separate surcharge.
• Original Medicare plus a Medigap policy: Medigap supplements Original Medicare; it is not Medicare Advantage. Having Medigap alone does not put you in the excluded Medicare Advantage group. Other rebate criteria still apply.

CMS uses slightly different wording when listing the Medicaid-assistance and IRMAA conditions in its online materials. If either condition might apply to you, get an individual eligibility answer from 1-800-MEDICARE (1-800-633-4227) rather than assuming you qualify.

When and how is the rebate paid?

The CMS payment FAQ says most eligible recipients were expected to receive a $90 direct deposit on or around October 8, 2026. Some recipients instead receive a paper check from the U.S. Treasury later in October, sent to the mailing address on record with Medicare. An email or mailed notice may arrive separately; the notice is not itself the payment.

This is described as an automatic payment, not a benefit for which Medicare directs people to buy a plan or submit a paid application. Do not assume that a missing deposit means you were denied: a paper check may still be on its way in late October.

No payment yet? Call the right agency

• To ask whether you qualify: Call 1-800-MEDICARE at 1-800-633-4227 (TTY 1-877-486-2048). Ask about the October 2026 Medicare Improvement Fund Part B premium rebate.
• To ask whether the payment was issued: CMS directs people to the Social Security Administration at 1-800-772-1213 beginning October 15, 2026. Tell the representative you are checking the one-time Medicare Part B rebate, not your ordinary monthly Social Security benefit.
• Before you call: Check your bank activity for a separate $90 deposit and your mail for a Treasury check. Keep any official letter, but do not share banking or Medicare numbers with an unsolicited caller.

A useful distinction: Medicare can check the eligibility rule, while Social Security is the contact CMS lists for delivery status. Calling the right place first may save an unnecessary transfer.

Does the $90 change your regular Medicare premium?

No. CMS published a $202.90 standard monthly Part B premium for 2026 in its 2026 premium fact sheet. The $90 is a separate one-time rebate for eligible recipients, not a reduction of the published standard premium to $112.90 each month. People who pay IRMAA have different premium amounts and are addressed separately in the eligibility rules.

Nor is this the same as Medicare Open Enrollment. The October 15–December 7 enrollment window generally changes plan coverage for January 1 of the following year. Do not switch coverage solely on the assumption that doing so will retroactively qualify you for this October 2026 payment.

Protect yourself from rebate scams

The payment announcement may prompt impostor calls or messages. Medicare warns people not to give their Medicare Number or personal details to unexpected callers, emails or visitors. If someone claims you must pay a fee or share bank credentials to release the $90, stop and contact Medicare through its published number yourself.
