For the period July 1, 2005, through June 30, 2006, we
estimated that Arizona paid approximately $500,000 ($335,000 Federal share) for
Medicaid services provided to beneficiaries who should not have been eligible
owing to their Medicaid eligibility/residence in California. Both Arizona and
California require that Medicaid beneficiaries be residents.
We recommended that Arizona work with the California Medicaid agency to share available Medicaid eligibility information for use in determining accurate beneficiary eligibility status and reducing the amount of payments, estimated to be approximately $500,000 ($335,000 Federal share), made on behalf of beneficiaries residing in California. Arizona acknowledged its obligation to review beneficiaries’ eligibility and identified several issues that it believed would reduce the reported payments. We reviewed Arizona’s comments and maintain that our findings remain valid.
