Governor Ducey has announced CHANGES he will propose to CMS in September. Arizona's AHCCCS (Medicaid) program is regulated by CMS (US Centers for Medicaid and Medicare Services). Changes are implemented using waivers which must be approved by CMS. For a taste of the energetic discussions taking place now in Arizona see Pro: Ducey's Medicaid Waivers and Con: Duceys' Medicaid Waivers.
