Arizona: what the PBM reimbursement law requires

Arizona requires PBMs to maintain and disclose MAC pricing lists and to offer a MAC appeals process, but it sets no minimum reimbursement — no NADAC or acquisition-cost floor.

Status	Partially enacted
Law	HB 2285 (2019) — A.R.S. § 20-3331
Effective date	January 1, 2020
Reimbursement basis	No reimbursement floor. PBMs must update MAC price and drug information every seven business days, disclose the sources used to determine MAC pricing, and establish a process for a network pharmacy (or its PSAO) to appeal MAC-based reimbursement.
Professional dispensing fee	Not specified in statute
Appeal route	PBM must maintain a MAC appeal process open to pharmacies and their PSAOs; the statute does not set a filing window or resolution deadline

Arizona regulates the mechanics of PBM pricing but does not guarantee a reimbursement floor. Under A.R.S. § 20-3331 (effective January 1, 2020), a PBM must keep its maximum-allowable-cost lists current — updated every seven business days — disclose the sources it uses to set MAC pricing, and provide a way for a network pharmacy or its pharmacy services administrative organization to appeal.

The statute requires that the appeal process exist but does not set statutory parameters such as a filing window or a resolution timeline, and it imposes no NADAC or acquisition-cost minimum on what a PBM pays.
