Montana Medicare Savings Programs for Disabled and Under-65 Beneficiaries

Medicare isn't only for people over 65. If you're receiving Social Security Disability Insurance (SSDI) in Montana, you become eligible for Medicare after a 24-month waiting period — and once you have Medicare, every cost-relief program available to seniors is available to you on the same terms.

The problem is that nobody tells you this clearly, and the financial pressure during those first months of Medicare coverage is often worse for younger disabled beneficiaries than for retirees.

You Qualify for the Same Programs as Seniors

Montana's Medicare Savings Programs — QMB, SLMB and QI — use the same income and resource limits regardless of age. If you're 38 and on SSDI with Medicare, you're evaluated against the same 2026 thresholds as a 72-year-old retiree:

• QMB: Countable income up to $1,330/month (individual), resources up to $9,950
• SLMB: Countable income up to $1,596/month, same resource limit
• QI: Countable income up to $1,796/month, same resource limit

QMB covers your Part B premium ($202.90/month), plus all Medicare deductibles, coinsurance and copayments. SLMB and QI cover the Part B premium only.

Apply through your local Office of Public Assistance, online at apply.mt.gov, or by calling 1-888-706-1535.

QDWI: The Program for Disabled Workers Who Returned to Work

There's a fourth Medicare Savings Program that specifically exists for disabled individuals: the Qualified Disabled Working Individual (QDWI) program.

QDWI is designed for people under 65 who:

• Were receiving SSDI
• Returned to work and lost their premium-free Part A coverage as a result
• Have countable income below 200% FPL ($2,660/month individual)
• Have resources below $4,000 (individual) or $6,000 (couple)

QDWI pays the Part A premium — either $278 or $505 per month in 2026 — so returning to work doesn't force you to choose between employment and hospital insurance.

Note the tighter resource limits compared to QMB/SLMB/QI: $4,000 versus $9,950. QDWI uses the old SSI resource standard, not the expanded limits that apply to the other three programs.

Big Sky Rx Works for Under-65 Too

Montana's Big Sky Rx program — the state's own prescription drug premium subsidy — explicitly covers Medicare beneficiaries under 65. The eligibility requirements are the same as for seniors:

• Montana resident
• Enrolled in Medicare and a Part D or MA-PD drug plan
• Gross annual income below $31,920 (individual) or $43,280 (couple)
• No asset test

Big Sky Rx pays up to $50.60/month toward your Part D plan premium. If your income is below 150% FPL, you'll need to apply for Extra Help through Social Security first and provide Big Sky Rx with your determination letter.

The 24-Month Waiting Period Gap

The hardest stretch for many disabled Montanans is the 24 months between SSDI approval and Medicare eligibility. During that gap, you may have no health coverage at all — or you're paying for Montana Medicaid if your income qualifies.

Once the waiting period ends and Medicare kicks in:

1. Apply for QMB, SLMB or QI through DPHHS (your MSP application)
2. If approved for any MSP, you're automatically deemed eligible for Extra Help — no separate SSA application needed
3. Apply for Big Sky Rx if your Part D premium isn't fully covered by Extra Help

The MSP application through DPHHS is the same Combined Application for Assistance that seniors use. There's no separate disability form for Medicare Savings Programs.

What About Working While on Medicare?

If you're working part-time while receiving SSDI and Medicare, your earned income gets favorable treatment in the MSP calculation. Montana applies the standard SSI earned income disregard: subtract $65 from gross earnings, then divide the remainder by half.

So if you're earning $500/month from part-time work, only $217.50 counts toward your MSP income limit — not the full $500. Combined with the $20 general unearned income disregard on your SSDI check, many working disabled Montanans still qualify for SLMB or QI even with a paycheck.

Our Montana Medicare Savings Programs, Extra Help & Big Sky Rx Guide includes worked income calculation examples and step-by-step filing instructions for the full three-layer system — MSP, Extra Help and Big Sky Rx — so you can see exactly where you land.
