Statutory Text
Analysis & Obligations
MCL 400.107b
Prohibition on AI-based Medicaid claims review
DeployerGovernment

1 Sec. 107b. The department or a contracted health plan shall not deny, modify, or delay a claim under the medical assistance program based on a review using artificial intelligence.

Section 107b adds a single operative provision to the Social Welfare Act prohibiting the Michigan Department of Health and Human Services and any contracted health plan from using artificial intelligence to deny, modify, or delay a claim under the medical assistance (Medicaid) program. The prohibition is categorical — it does not require that AI be the sole or primary basis for the adverse determination, nor does it carve out AI use with human oversight. Any review "using" AI that results in a denial, modification, or delay is prohibited.

The bill contains no definitions of "artificial intelligence," "claim," or "contracted health plan," leaving those terms to be interpreted under existing Michigan law and administrative practice. It also contains no enforcement mechanism, penalties, or private right of action — compliance would presumably be enforced through existing Medicaid administrative processes and judicial review.

The Michigan Department of Health and Human Services and any contracted health plan must not deny, modify, or delay a claim under the Medicaid medical assistance program based on a review using artificial intelligence. This is a categorical prohibition — it bars any AI-based review that results in an adverse claims determination, regardless of whether a human also participated in the review.
