Why Did I Get a $90 SSA TREAS 310 Deposit? What Seniors Should Know
This morning I noticed something unusual in our bank account.
There were two pending deposits for $90 each, both labeled “SSA TREAS 310.”
My wife and I both receive Social Security, but these were not our normal monthly payments. One of us receives Social Security on the third Wednesday of the month and the other on the fourth Wednesday.
So naturally, my first question was:
What are these $90 payments, and are they legitimate?
The answer is yes.
The $90 Payment Is a Medicare Rebate
The Centers for Medicare & Medicaid Services says certain people enrolled in Original Medicare Part B are receiving a one-time $90 Medicare Improvement Fund Premium Rebate in October 2026.
Most eligible people receiving direct deposit are expected to see the money on or around October 8.
That’s exactly what happened in our case. Our bank showed two pending $90 deposits scheduled for October 8—one for each of us.
Why Does It Say “SSA TREAS 310”?
Although this payment is connected with Medicare, most eligible beneficiaries are receiving it through the Social Security Administration by direct deposit.
That is why your bank may show a description such as:
SSA TREAS 310
It may look like an extra Social Security payment, but it is actually the Medicare rebate being delivered through Social Security.
Who Qualifies for the $90 Payment?
According to CMS, approximately 20.8 million Americans are eligible.
Generally, you must:
- Be enrolled in Original Medicare Part B
- Live in the United States
- Not receive Medicaid assistance paying your Medicare premium
- Not pay the higher Medicare premium known as IRMAA because of higher income
People enrolled in Medicare Advantage are not eligible for this particular payment.
So don’t be concerned if a friend or relative receives $90 and you don’t. Eligibility depends on the type of Medicare coverage and other circumstances.
What If You Don’t Use Direct Deposit?
CMS says some eligible beneficiaries who don’t receive direct deposit will receive a $90 Treasury check later in October.
The check should indicate that it is a Medicare Improvement Fund payment intended to help offset the October premium.
Do You Have to Apply?
No.
Eligible beneficiaries do not have to submit an application or provide banking information to receive this payment.
That’s worth remembering because whenever unexpected government payments appear, scammers are not far behind.
If you receive a phone call, text or email telling you that you need to provide your Social Security number, Medicare number, bank information or pay a fee to receive your $90, don’t do it.
How Can You Check Your Eligibility?
CMS says Medicare beneficiaries can call 1-800-MEDICARE (1-800-633-4227) to ask about eligibility.
If you’re expecting a payment but haven’t received it, CMS says you can contact the Social Security Administration at 1-800-772-1213 beginning October 15, 2026 to check the payment status.
What I Learned From Our Own $90 Deposits
When I first saw SSA TREAS 310 and $90 sitting in our pending transactions, I didn’t immediately know what it was.
And these days, when an unexpected financial transaction appears, I think it’s smart to ask questions before assuming anything.
In our case, the explanation was simple.
My wife and I are each receiving the $90 Medicare rebate, for a total of $180.
So if you noticed an unexpected $90 SSA TREAS 310 deposit this week, don’t panic.
It may very well be your Medicare rebate.
And if you’re uncertain, verify it through Medicare or Social Security rather than trusting a phone call, text message or social-media post.
At our age, a little caution can save a lot of trouble.
