Michigan and Montana: health record laws compared
Michigan and Montana, side by side on the seven questions, with the laws read October 3, 2026. They give different answers on health data outside HIPAA, getting a copy, right to sue and breach notice, and the same answer on everything else.
The seven questions, side by side
"Differs" marks a question where the answers are not the same; "same" marks one where they are. "Can't compare" means at least one answer was not checked; a not-checked answer is not a no. Where a question has a map, the small square shows the color each column has on it. Each citation opens that state's page, with the law quoted, dated and linked. There is no total and no rank: the questions are on different scales, and some have no best answer.
