    (a) For Michigan pharmacies with not more than 7 retail outlets, utilize a pharmacy reimbursement methodology of the lesser of national average drug acquisition cost plus a professional dispensing fee that is at least equal to the applicable professional dispensing fee provided through section 1620 of article 6 of 2020 PA 166, wholesale acquisition cost plus a professional dispensing fee provided through section 1620 of article 6 of 2020 PA 166, or the usual and customary charge by the pharmacy. The pharmacy benefit manager or the involved pharmacy services administrative organization shall not receive any portion of the professional dispensing fee. The department shall identify the pharmacies this subdivision applies to and provide the list of applicable pharmacies to the Michigan Medicaid managed care organizations.

    (b) Reimburse for a legally valid claim at a rate not less than the rate in effect at the time the original claim adjudication was submitted at the point of sale.

    (d) Agree to not create new pharmacy administration fees and to not increase current fees more than the rate of inflation. This subdivision does not apply to any federal rule or action that creates a new fee.

    (e) Agree to not terminate an existing contract with a Michigan pharmacy with not more than 7 retail outlets for the sole reason of the additional professional dispensing fee authorized under this section.

    (2) This section does not prohibit a Medicaid managed care organization from implementing this section before the effective date of the amendatory act that added this section.
