Arkansas Pharmacies File First Lawsuit Against Express Scripts Under State PBM Payment Law
Twelve independent Arkansas pharmacies filed suit against Express Scripts, marking the first use of a 2025 state law authorizing pharmacies to sue pharmacy benefit managers for underpayments. The lawsuit tests new enforcement authority granted to pharmacies under Arkansas legislation targeting PBM reimbursement practices. The case could establish precedent for pharmacy challenges to PBM payment methodology in Arkansas and influence similar legislative efforts in other states. The outcome affects Medicaid managed care plans that contract with Express Scripts for pharmacy services and may impact PBM reimbursement practices across state Medicaid programs.
The lawsuit establishes the first test of state-level private enforcement mechanisms targeting PBM payment practices, potentially affecting how Medicaid managed care plans structure pharmacy contracts and reimburse network pharmacies.
