Mississippi Medicare Savings Program for Disabled Under 65

Medicare isn't just for people over 65. Most people receiving Social Security Disability Insurance (SSDI) become eligible for Medicare after a 24-month waiting period. People with ALS generally qualify when SSDI starts, and ESRD has separate Medicare eligibility rules. Once Medicare coverage begins, the same Medicare Savings Programs available to seniors are available to you.

But the application process has a few wrinkles that don't apply to the 65-and-older crowd.

How Disabled Individuals Under 65 Get Medicare in Mississippi

For most SSDI beneficiaries, Medicare Part A and Part B begin after a 24-month waiting period that starts with the first month of SSDI entitlement, not when the approval letter arrives. People with ALS generally qualify when SSDI starts; ESRD has separate rules.

Once Medicare coverage activates, a disabled beneficiary under 65 can apply to the Mississippi Division of Medicaid (DOM) for QMB, SLMB, or QI under the same rules as any other Medicare beneficiary. DOM evaluates these applications under its Aged, Blind, and Disabled (ABD) eligibility criteria.

The key facts:

• No asset test for QMB, SLMB, and QI in Mississippi — savings, vehicles, and property don't count
• Same 2026 income limits as for seniors: below $1,380/month for an individual in QMB, $1,646 in SLMB, or $1,846 in QI (state-published limits already reflect Mississippi's $50 general income exclusion)
• Same benefits: QMB covers Part A and B premiums plus all deductibles and copays; SLMB and QI cover the Part B premium only

The one exception is QDWI (Qualified Disabled and Working Individual), a program that exists specifically for disabled individuals under 65 who returned to work and lost premium-free Part A. QDWI pays the Part A premium ($565/month for fewer than 30 quarters, or $311/month for 30–39 quarters in 2026) and retains an asset limit of $4,000 for an individual or $6,000 for a couple.

The ABD Application at DOM

Mississippi uses a single application form — Form DOM-300 — for all ABD categories, including MSPs. When a disabled person under 65 applies, DOM looks at:

1. Medicare entitlement: proof that Part A is active (Medicare card showing the Part A effective date)
2. Income: gross monthly income from SSDI, any pensions, and earned income if working
3. Mississippi residency: utility bill, lease, or similar documentation
4. Citizenship or qualified immigration status

If the applicant's disability is already established through SSI or SSDI, DOM does not require a separate disability determination for MSP purposes. The SSDI award letter serves as proof.

Processing takes up to 45 calendar days for aged or blind applicants and up to 90 calendar days when the application involves a separate disability determination. For most SSDI recipients applying for MSPs, the 45-day standard applies because disability is already established.

Working While Disabled: How Earned Income Is Counted

For QMB, SLMB, and QI, Mississippi's income calculation includes earned income disregards that benefit working disabled individuals substantially. These are not the QDWI income rules:

1. Subtract the $50 general income exclusion (Mississippi's liberalized rate, not the federal $20)
2. From earned income, subtract $65
3. Divide the remaining earned income in half

So someone earning $2,000/month from part-time work:

• $2,000 − $50 = $1,950
• $1,950 − $65 = $1,885
• $1,885 ÷ 2 = $942.50 countable income

That's well under the QMB limit. Many disabled Mississippians who work part-time assume their paycheck disqualifies them when the math actually puts them solidly in range.

QDWI: When You Lose Premium-Free Part A

QDWI fills a narrow but critical gap. If a disabled person under 65 completes their trial work period and extended period of eligibility, and Social Security determines they're engaging in substantial gainful activity, premium-free Part A eventually ends.

At that point, keeping Part A means paying the full premium — $565/month for fewer than 30 quarters, or $311/month for 30–39 quarters in 2026. QDWI covers that premium, but the requirements are tighter than other MSPs:

• 2026 income standard of $5,405/month for an individual under QDWI's SSI income rules, including earned-income exclusions
• Asset limit applies: $4,000 individual, $6,000 couple
• Cannot be enrolled in full Medicaid simultaneously

QDWI is the only MSP in Mississippi that still enforces an asset test. If someone qualifies for QMB instead (income at or below 100% FPL), QMB is the better option — it covers Part A premiums, Part B premiums, and all cost-sharing, with no asset test.

What to Do Next

If you're under 65 with Medicare through SSDI, start by checking whether your gross monthly income falls under the 2026 MSP income limits. Remember that Mississippi applies a $50 disregard and generous earned income exclusions — your countable income is likely lower than your bank deposit.

The Mississippi Medicare Savings Programs & Extra Help Guide includes the full ABD application walkthrough, income calculation worksheets, and the documents you'll need at the DOM regional office. It covers the specific scenarios disabled beneficiaries face, including the QDWI application process and what happens if your SSDI amount changes at your next continuing disability review.
