The resolution HCR2058 proposes a constitutional amendment to conduct a comprehensive audit of Arizona's Medicaid Program, which is administered by the Arizona Health Care Cost Containment System (AHCCCS). The audit aims to review all payments made under the Medicaid program in the three years preceding the audit and will be coordinated with the Centers for Medicare and Medicaid Services. The Joint Legislative Budget Committee (JLBC) Director is tasked with issuing a request for proposals from qualified audit vendors within 180 days of the measure's effective date. The audit report will categorize any identified misappropriations by provider type and managed care organization, while ensuring that personal identifying information and confidential commercial data are redacted from public reports.

Additionally, the resolution outlines that the costs of the audit will be covered by recoveries from misappropriated claims, with any remaining funds deposited into the state General Fund. The JLBC Director and AHCCCS are required to negotiate settlements for misappropriated claims within 90 days of the audit report's issuance, and unresolved matters will be referred to the Attorney General for potential legal action. The resolution mandates that the JLBC Director report the total amount of misappropriated claims and recovered funds to key government officials within nine months of the audit report. This measure will be submitted to voters at the next general election and is set to be repealed on December 31, 2030.
