Idaho Medicare Savings Program: Who Qualifies and What It Covers

What the Idaho Medicare Savings Program Actually Does

Your parent's Social Security check arrives, and $202.90 vanishes before they can spend a dollar — that's the Part B premium Medicare deducts automatically. For a senior living on $1,300 a month in Pocatello or Twin Falls, that's groceries for two weeks.

Idaho's Medicare Savings Programs pay some or all of those Medicare costs through the Department of Health and Welfare (DHW). Three main tiers exist, each covering a different income range and a different slice of Medicare expenses. A fourth tier, QDWI, covers a narrow group of disabled workers.

The Three Tiers: QMB, SLMB, and QI

Qualified Medicare Beneficiary (QMB) is the most comprehensive. It covers the Part B premium, the Part A premium (if your parent pays one), plus all Medicare deductibles, coinsurance, and copays. Doctors and hospitals cannot bill a QMB enrollee for any of those costs — federal law prohibits it. For 2026, an individual qualifies with countable income up to $1,350 per month and countable resources under $9,950.

Specified Low-Income Medicare Beneficiary (SLMB) covers the Part B premium only — that $202.90 monthly deduction from Social Security. Income can be up to $1,616 per month for a single person. Same resource limit: $9,950.

Qualifying Individual (QI) also covers the Part B premium. The income ceiling is higher at $1,816 per month for individuals. Resources still cannot exceed $9,950. QI funding comes from a capped federal allotment.

All three tiers automatically trigger Extra Help, the federal program that cuts Part D prescription drug costs to small copays of $5.10 for generics and $12.65 for brand-name drugs.

Couple Limits for 2026

Married couples applying together use higher thresholds: $1,824 per month for QMB, $2,184 for SLMB, and $2,455 for QI. The couple resource limit is $14,910 across all three tiers.

When only one spouse has Medicare and both live together, DHW still counts combined household income against the couple limit. If spouses are permanently separated and living apart, each person is evaluated individually using the single-person thresholds.

How DHW Counts Income

Idaho uses gross Social Security — the amount before Part B premiums or tax withholdings are deducted, not the deposit that lands in the bank account. A $20 monthly general income disregard is subtracted from unearned income. For earned wages, DHW excludes the first $65 and then half of what remains.

This is where many families assume a parent doesn't qualify and never apply. A gross Social Security check of $1,365 looks too high for QMB's $1,350 limit — until the $20 disregard brings countable income down to $1,345.

Who Runs the Program

DHW's Division of Self-Reliance processes all MSP applications. You can apply through the idalink portal at idalink.idaho.gov, by mailing or faxing Form HW2019 to the centralized intake office, or by calling 1-877-456-1233. SHIBA (Senior Health Insurance Benefits Advisors) counselors through the Idaho Department of Insurance offer free, unbiased help at 1-800-247-4422 — they don't sell insurance.

Checking Whether Your Parent Qualifies

Start with two numbers: your parent's gross monthly Social Security benefit (from their award letter or my Social Security account, not the bank deposit) and the total balance across all bank accounts, CDs, and investments. The primary home, one car, and designated burial funds don't count toward the resource limit.

If gross income after the $20 disregard falls under $1,816 for a single person and resources are under $9,950, your parent likely qualifies for at least one tier. The Idaho Medicare Savings Programs & Extra Help Guide walks through the eligibility math step by step, with worksheets for gross-to-net income conversion and a document checklist built around what DHW actually asks for.

What Happens After Approval

DHW notifies CMS and SSA electronically. For SLMB and QI, the Part B premium deduction stops within 30 to 90 days, and SSA sends a retroactive reimbursement check covering premiums already paid during the processing period. SLMB and QI coverage can be backdated up to three calendar months before the month of application, provided the applicant met the criteria in those months. QMB coverage starts the first day of the month after approval — no retroactive coverage, so applying sooner matters.

The approval also triggers automatic Extra Help enrollment for Part D, eliminating the Part D plan premium on benchmark plans and capping drug copays.
