Health: pharmaceuticals; drug manufacturers from engaging in certain conduct with pharmacies participating with a 340B program; prohibit. Amends 1978 PA 368 (MCL 333.1101 - 333.25211) by adding sec. 17757c.

This bill prohibits pharmaceutical manufacturers and wholesalers from denying or limiting access to discounted 340B drugs for eligible healthcare organizations and their authorized pharmacies. It also bans these companies from appointing agents to carry out such restrictions, though it allows actions that are already permitted by existing state or federal laws. Starting in 2026, the law requires healthcare organizations and drug makers to submit detailed annual reports to the state department regarding program compliance and specific high-cost medications with significant price increases. These reports must be made publicly available on the department's website to increase transparency. The legislation does not take effect unless another related bill is also passed into law.
