SB 252 changes how Oklahoma's Medicaid program covers prescription drugs. It requires the Oklahoma Health Care Authority (OHCA) to transition all Medicaid members' prescription drug coverage from contracted health plans to a direct fee-for-service model, meaning OHCA will directly pay pharmacists and pharmacies instead of using managed care contracts. The bill prohibits OHCA from contracting with pharmacy benefits managers (PBMs) but allows participation in the Medicaid Drug Rebate Program and value-based payment arrangements. This change affects all Medicaid beneficiaries covered under existing managed care contracts, with implementation dependent on federal approval.
