(5) If the director grants a waiver under subsection (3), the waiver expires after 2 years. If a pharmacy benefit manager seeks a renewal of the waiver, the director must consider the steps that the pharmacy benefit manager has taken over the 2-year period covered by the waiver to address network adequacy.

(6) A pharmacy benefit manager shall not conduct spread pricing in this state. However, if a contract between a plan sponsor and a health plan is in effect on the effective date of this act and the contract conflicts with this subsection, for that contract, this subsection applies to the pharmacy benefit manager beginning on the date the contract is amended, extended, or renewed, or before January 1, 2028, whichever is earlier.

(7) A pharmacy benefit manager shall not charge a pharmacy or pharmacist a fee to process a claim electronically.
