The resolution H.C.R. 2058 proposes a comprehensive audit of Arizona's Medicaid program, which is administered by the Arizona Health Care Cost Containment System (AHCCCS). Subject to voter approval, it mandates the Director of the Joint Legislative Budget Committee (JLBC) to contract with a qualified audit vendor to conduct a detailed claim-level audit of all payments made under the Medicaid program over the past three years. The audit aims to identify misappropriated claims, which include improper payments, duplicate payments, and payments for ineligible services. The audit process will be coordinated with the U.S. Centers for Medicare and Medicaid Services (CMS) and will require the auditor to redact any personal identifying information from public reports.

Additionally, the resolution outlines procedures for addressing any identified misappropriations, including negotiating settlements within 90 days of the audit report and referring unresolved matters to the Attorney General for potential legal action. The costs of the audit will be covered by the recoveries from misappropriated claims, with any remaining funds deposited into the state General Fund. The JLBC is also tasked with reporting the total amount of recovered claims to state leadership within nine months of the audit's completion. The provisions of this resolution will be repealed after December 31, 2030, unless extended, and it will take effect only if approved by voters and proclaimed by the Governor.
