Insurance: health insurers; procedures and timelines for the credentialing of health care providers; provide for. Amends 1956 PA 218 (MCL 500.100 - 500.8302) by adding sec. 3406uu. TIE BAR WITH: HB 5513'26

HB 5512 sets clear timelines for health insurers to process applications from healthcare providers seeking to join their provider networks. Insurers must acknowledge receipt within 7 days, notify providers of incomplete applications within 30 days (giving them 30 days to fix issues), and complete the credentialing process within 60 days total. If approved, insurers must reimburse providers for covered services starting from when the completed application was received. This directly affects doctors, clinics, and other healthcare providers applying to be in insurer networks, ensuring faster access to network participation.
