Michigan MI Bridges Application for Disability Benefits

MI Bridges is the online portal where Michigan processes Medicaid applications, food assistance, cash assistance, and child care benefits. For families navigating disability benefits at age 18, it's the digital front door to adult Medicaid enrollment — and the interface between your family and the massive MDHHS Bridges Eligibility Manual that caseworkers use to make eligibility decisions.

Setting Up the Account at Age 18

Your adult child needs their own MI Bridges account. Before their 18th birthday, they were covered under your household's Medicaid case. After 18, they apply as a single-person household — even if they still live with you.

Go to newmibridges.michigan.gov and create an account using your adult child's personal information. You'll need their Social Security number, date of birth, and a valid email address. If your adult child cannot manage the account independently, you can register as an "authorized representative" through the portal to manage applications on their behalf.

Filing the Medicaid Application

For disability-related Medicaid, you're filing for Medical Assistance under the Aged, Blind, and Disabled (AD-Care) category. The key fields to get right:

Household size: File as a one-person household. Even though your adult child lives in your home, the adult Medicaid application treats them as their own economic unit. Parental income and assets are not counted.

Countable assets: For most SSI-related Medicaid categories, the 2026 countable-asset threshold is $9,950 for a single individual. List assets under the applicable BEM rules. The first $100,000 in a MiABLE account is excluded from SSI resources, and ABLE balances are disregarded for Medicaid resource testing within the applicable plan limit.

Income reporting: Report all unearned income (SSI, DAC benefits, any other payments). The income limit for AD-Care Group 1 Medicaid is 100% of the Federal Poverty Level — $1,330 per month in 2026. If your adult child's income exceeds this, they may be assigned to the Medically Needy (spend-down) program, where they must submit proof of medical expenses each month to activate coverage.

Disability documentation: Upload or be prepared to submit diagnostic evaluations, treatment records, and functional assessments establishing the disability. Keep the SSA disability determination with those records if SSI has been approved.

The Section 1634 Shortcut

Michigan is a Section 1634 state, which means individuals who qualify for SSI are automatically enrolled in Medicaid without filing a separate application through MI Bridges. If your adult child's SSI application has been approved, verify that the automatic Medicaid activation worked by checking MI Bridges for an active Medical Assistance case.

If the automatic transmission fails, file form DCH-1426 (Application for Health Coverage & Help Paying Costs) through MI Bridges immediately. Do not wait for the system to self-correct.

The Bridges Eligibility Manual Connection

The Bridges Eligibility Manual (BEM) is the policy manual that MDHHS caseworkers reference when determining your adult child's eligibility. Understanding the relevant BEM sections helps you anticipate what the caseworker is looking for:

• BEM 400 — asset limits ($9,950 individual, $14,910 couple)
• BEM 158 — DAC Medicaid protection (maintains coverage when SSI terminates due to DAC benefits)
• BEM 154 — Special Disabled Children provisions
• BEM 171/172 — waiver program eligibility rules

When a caseworker makes a determination you disagree with, referencing the specific BEM section in your appeal strengthens your case. The manual is publicly available on the MDHHS website.

Common Application Mistakes

Filing under the parents' case: Apply in the adult child's own name and report the young adult's own household, income, and assets. Ask MDHHS how to link the application to an existing household case.

Submitting MDHHS-1171 without the Healthcare Coverage Supplement: The integrated multi-program application (MDHHS-1171) requires the designated Healthcare Coverage Supplement to register a Medicaid case. Submitting the standard form alone is legally insufficient.

Missing the retroactive coverage window: Form DHS-3243 allows you to request up to three months of retroactive Medicaid coverage when filing a new application. If your adult child had qualifying medical expenses in the months before the application, file the retroactive request alongside the DCH-1426.

Keeping Everything Organized

The Michigan SSI at 18 & Adult Disability Benefits Guide coordinates the MI Bridges application with the SSI filing, CMHSP intake, and HSW waiver screening — so you don't miss the retroactive coverage window or file the wrong form at the wrong time.
