This audit evaluated whether Aetna and Caremark had controls to ensure net reimbursements to pharmacies, accurate reporting to Texas HHSC, and compliance with the Uniform Managed Care Contract for Texas Medicaid and CHIP pharmacy benefits during state fiscal years 2020 and 2021. It found unallowable pricing practices and reporting deficiencies, with scope limitations due to Caremark access restrictions, and recommended actions to exclude Texas Medicaid and CHIP from effective rate adjustments, end spread pricing practices, improve reporting, and enhance oversight.
