Insurance: health insurers; limit amount on co-pay for prescription insulin; provide for. Amends 1956 PA 218 (MCL 500.100 - 500.8302) by adding sec. 3406qq.

This bill requires health insurance companies in Michigan to limit the co-pay or coinsurance for insulin to no more than $35 per 30-day supply. The rule applies to at least one product within each major type of insulin, including rapid-acting, long-acting, and premixed varieties, and prevents insurers from bypassing this limit by raising costs elsewhere or changing benefit categories. While the $35 cap is set as a maximum, insurers are allowed to charge less, and the limit only applies to insulin products; other medical costs can remain higher. The amount will be automatically adjusted each July starting in 2027 based on changes in the local Consumer Price Index.
