Poor Accountability and Transparency Harm Medicaid Patients and Independent Pharmacies
Learn how the AI-generated research projects were createdOverall Conclusion
The audit identifies Oregon’s Medicaid PBM framework as overly complex and insufficiently transparent, with limited direct oversight of PBMs by OHA. The report recommends a shift toward stronger patient and pharmacy protections, uniform formularies, fiduciary duties for PBMs, and centralized procurement approaches to improve value and protect independent pharmacies.

Audit Scope
Scope includes Oregon Medicaid prescription drug benefits administered by the Oregon Health Authority and contracted with 16 Coordinated Care Organizations (CCOs) and six PBMs, including related entities and data through 2021-2023; covers spending and utilization patterns, contract oversight, and the interplay among OHA, CCOs, PBMs, pharmacies, wholesalers, and manufacturers.
Key Findings Summary
Oregon's regulation of PBMs is limited and fragmented; other states have meaningful legislation targeted at patient protections, pharmacy protections, and transparency.
The current structure of Medicaid PBMs is too complex for the State to efficiently measure value; involves 16 Coordinated Care Organizations (CCOs), six PBMs, hundreds of pharmacies, multiple drug manufacturers, wholesalers, pharmacy administrative organizations, OHA, and the Department of Consumer and Business Services, among others.
Pharmacy reimbursements vary significantly depending on the drugs, pharmacy type, and PBM; national chains reimbursed twice the amount independent pharmacies were for selected drugs.

AI Scope Summary
Building on this audit's findings, future audits should focus on validating the implementation of recommended reforms, such as establishing a uniform Medicaid formulary, fiduciary duties for PBMs, and pass-through pricing; assess the effectiveness of OHA and DCBS in monitoring PBMs; quantify changes in independent pharmacy access and patient protections; and evaluate the potential cost savings and operational impacts of moving to a single PBM or FFS model, as well as exploring centralized purchasing programs.
AI-Generated Insight
This report highlights a fragmented and opaque Medicaid PBM landscape in Oregon, where complex contracts and proprietary pricing hinder transparent oversight. It argues for reform through uniform formularies, fiduciary PBMs, and centralized purchasing to enhance patient protections, pharmacy access, and taxpayer value. The recommended moves align with leading-state practices to increase transparency and accountability in the prescription drug supply chain.
