Here is a blunt fact: the standard Medicare Part B premium is $202.90 a month in 2026, which comes to about $2,435 a year, deducted from Social Security checks that average well under $2,100 a month. And here is the fact that should follow it everywhere: for millions of lower-income beneficiaries, a state program will pay that premium — and sometimes nearly all other Medicare cost-sharing — yet a large share of eligible people never apply. These are the Medicare Savings Programs, and they are the most underused money in the entire Medicare system.

The four programs, from most generous down

QMB: Qualified Medicare Beneficiary

QMB is the full ride. The state pays your Part B premium (and Part A premium if you owe one), plus your Medicare deductibles, coinsurance, and copayments. Under Original Medicare with QMB, your share of the cost of covered services is essentially zero. QMB also carries a legal shield: federal law prohibits providers from billing QMB enrollees for Medicare cost-sharing at all. If a provider bills you anyway — it happens constantly, usually by clerical error — you do not owe it, and the provider is required to refund anything you paid.

SLMB and QI: the premium payers

Specified Low-Income Medicare Beneficiary (SLMB) and Qualifying Individual (QI) both pay the Part B premium only, at successively higher income limits. That alone puts about $2,435 a year back in your pocket in 2026. QI has one quirk: it is funded by annual allotment and technically first come, first served, so apply early in the year rather than late.

QDWI: the rare fourth program

Qualified Disabled and Working Individuals pays the Part A premium for certain disabled people who returned to work and lost premium-free Part A. Few people fit this box, but if you do, it is worth real money.

Income and asset limits: check before you self-reject

Limits update each spring when the new poverty guidelines flow through. The 2025 monthly income limits give you a close idea of where the lines sit — 2026 figures land slightly higher:

  • QMB: about $1,325 for an individual, $1,783 for a couple
  • SLMB: about $1,585 individual, $2,135 couple
  • QI: about $1,781 individual, $2,400 couple
  • Assets (QMB/SLMB/QI): about $9,660 individual, $14,470 couple — your home, one car, and household goods do not count

Now the part that matters more than the table: those are the federal floors, and the counting rules bend in your favor. At least $20 a month of income is disregarded automatically, half of earned income above a threshold is ignored, and several states use more generous limits or have dropped the asset test entirely — a few disregard assets altogether, and others have eliminated the test for some programs. In our experience reading state manuals, the single most common mistake is seniors comparing their gross Social Security check to the limit and concluding they miss by $50, when the disregards would have put them under. Do not do the math yourself; make the state do it. Current federal figures are listed at medicare.gov.

The hidden bonus: automatic Extra Help

Enrollment in QMB, SLMB, or QI automatically qualifies you for Extra Help, the federal subsidy that slashes Part D prescription costs to a few dollars per fill and eliminates the drug plan's premium and deductible for benchmark plans. The Social Security Administration values Extra Help at thousands of dollars a year by itself, so an approved MSP application is really two approvals stapled together. Stack the Part B premium, the cost-sharing (for QMB), and the drug subsidy, and a successful application can be worth $5,000 or more a year to a low-income household.

How to apply

You apply through your state Medicaid agency, not through Medicare or Social Security — even though the benefit is about Medicare premiums. Three routes:

  1. Call your state Medicaid office and ask for the "Medicare Savings Program application." Many states take applications by phone or mail with a short form.
  2. Apply online through your state's benefits portal, listed at medicaid.gov.
  3. Get free one-on-one help from your State Health Insurance Assistance Program (SHIP) counselor — find yours through the national directory or by calling 1-877-839-2675.

Have ready: proof of income (Social Security award letter, pension statements), bank statements for the asset test if your state has one, and your Medicare card. States must process the application and send a written decision; if you are denied, the notice explains your appeal rights, and appeals succeed more often than people expect when the issue is income counting.

What approval looks like, and staying enrolled

Once approved, the state begins paying the Part B premium directly to Medicare through what is called the buy-in. The mechanics take a billing cycle or two to settle, and here is a pleasant quirk worth knowing in advance: because the buy-in is often effective back to your application month (or earlier for some programs), Social Security frequently refunds premiums that were withheld during processing, arriving as a surprise deposit. Do not panic and assume it is an overpayment you must return; check the accompanying notice.

Enrollment is not permanent by default. States redetermine MSP eligibility annually, usually by mail, and the renewal form is where people fall off — not because their income rose, but because the envelope looked like junk and the deadline passed. Treat anything from your state Medicaid agency the way you treat mail from the IRS. If you are terminated for missing paperwork, reapply immediately; there is no lockout period.

Timing and knock-on effects

Approval is not retroactive to your Medicare start date, so every month you wait is a premium you paid unnecessarily. Once enrolled, the Part B premium stops coming out of your Social Security check, which reads like a raise of about $203 a month. Note one interaction: because MSP enrollment routes through Medicaid systems, it sometimes surfaces other help you qualify for — SNAP being the usual suspect. If you are 60 or over and have never done a full benefits checkup, our rundown of benefits every senior should review is the logical next stop, and if you are new to Medicare entirely, start with our plain-English enrollment guide so the premiums you are asking the state to pay make sense in context.

If your income is anywhere near the numbers above, apply this month. The worst case is a denial letter that cost you a stamp; the base case is $2,400 a year, every year, for the rest of your retirement.
