In April 2022, legislation promising prior authorization (PA) reform was signed into law by Governor Whitmer. The goal of the new law (Public Act 60 of 2022) is making the PA process faster, more effective, and transparent. It includes a standardized electronic prior authorization request transaction process, a requirement that prior authorization requirements be based on peer-reviewed clinical review criteria that meet certain requirements, and expedited review timelines. The new law is fully effective as of June 1, 2023.
