The $90 Medicare Part B Premium Rebate: Who Qualified and How to Check

If you have Original Medicare and heard about a $90 rebate landing in October 2026, you're not imagining it. The Centers for Medicare & Medicaid Services (CMS) made a one-time $90 Medicare Improvement Fund Premium Rebate available to help offset the October 2026 Part B premium for certain people. Here's a plain-English look at who qualified, how the money arrived, and how to check on your payment.

What the rebate is

In October 2026, CMS announced one $90 Medicare Improvement Fund Premium Rebate for certain people enrolled in Original Medicare Part B. Medicare.gov describes it as a one-time payment of $90 to offset the October 2026 Part B premium. For context, the standard monthly Part B premium in 2026 is $202.90, and the annual Part B deductible is $283.

The Medicare Improvement Fund itself isn't new. It was created by Section 7002 of the Supplemental Appropriations Act of 2008 to fund improvements under the original fee-for-service program (Parts A and B). The October 2026 rebate is being paid from that fund.

Who qualified

According to CMS's FAQ dated October 3, 2026, the rebate went to "the 20.8 million Americans in Original Medicare Part B who are: (1) Living in the United States, are (2) not receiving premium assistance from Medicaid; or, (3) not paying an Income-Related Monthly Adjustment Amount" (IRMAA).

In short, three groups were excluded:

• People enrolled in Medicare Advantage. CMS and Medicare.gov both confirm that Medicare Advantage enrollees are not eligible.
• People whose Part B premium is paid by Medicaid (for example, through a Medicare Savings Program).
• People paying an IRMAA surcharge on top of the standard Part B premium because of higher income.

If you have Original Medicare Part B, live in the U.S., pay your own standard Part B premium, and aren't subject to IRMAA, you were in the eligible group.

How the money arrived

CMS said most eligible people would receive the $90 by direct deposit from the Social Security Administration on or around October 8, 2026. A confirmation email or letter followed in mid-October.

If you don't have direct deposit set up with Social Security, a $90 paper check from the U.S. Department of the Treasury was mailed later in October 2026 to the address you have on file with Medicare. The check carries the message: "Medicare Improvement Fund Payment; $90 Payment to Offset October Premium." If you've moved recently, make sure your mailing address is current with Medicare and Social Security so a check doesn't go astray.

How to check your eligibility or payment

CMS points to two different phone numbers depending on your question:

• To check whether you qualify for the rebate, call 1-800-MEDICARE (1-800-633-4227).
• To check the status of a payment, call the Social Security Administration at 1-800-772-1213 beginning October 15, 2026.

Be cautious about scams. Medicare will not call, text, or email you asking for your bank information, Social Security number, or a fee to "release" your $90. If anyone contacts you that way, hang up and call 1-800-MEDICARE directly.

While you're thinking about Medicare: a few 2027 reminders

The rebate is a one-time event, but fall is also when the big annual Medicare decisions happen. A few national facts worth knowing:

• Annual Enrollment (also called Open Enrollment) runs October 15 – December 7, 2026, with any changes taking effect January 1, 2027. This is when you can switch between Original Medicare and Medicare Advantage, change Part D drug plans, or pick up a new plan.
• The Part D out-of-pocket cap rises to $2,400 in 2027 (up from $2,100 in 2026). After you hit that cap, you pay $0 for covered drugs for the rest of the year.
• The most any Part D plan can charge as a deductible in 2027 is $700.
• The Part D base beneficiary premium for 2027 is $41.33. That's a national figure used to calculate the late-enrollment penalty; actual plan premiums are set plan by plan.
• The Social Security Administration announced a 3.6% cost-of-living adjustment (COLA) on October 14, 2026, for benefits payable beginning January 2027.

The 2027 standard Part B premium and deductible, along with the IRMAA income brackets, had not yet been announced as of this writing. CMS typically publishes them in the fall. Watch Medicare.gov for the official figures.

Medicare Advantage vs. Original Medicare + Medigap: a quick, neutral note

Because the rebate only applies to Original Medicare, some readers may be reviewing their broader coverage. Both paths have trade-offs. Original Medicare paired with a Medigap policy and a stand-alone Part D plan generally offers broad provider access nationwide and predictable out-of-pocket costs, but Medigap premiums are an added monthly expense. Medicare Advantage plans bundle coverage and often include extras, but typically use provider networks and prior authorization. There's no universal "better" choice — it depends on your health, budget, providers, and preferences.

A note for people with Medicaid or Extra Help

Since 2025, people with Medicaid or Extra Help have a monthly Special Enrollment Period to move to Original Medicare with a stand-alone Part D plan, or to switch stand-alone Part D plans. Full-benefit dual-eligible individuals can also join an integrated D-SNP in any month. You don't have to wait for Annual Enrollment to make these changes.

Where to go next

For the most current, official information — including 2027 Part B figures when they're announced — visit Medicare.gov or call 1-800-MEDICARE (1-800-633-4227), available 24/7. For questions about a rebate payment specifically, Social Security at 1-800-772-1213 is the right number starting October 15, 2026.
