For Providers

Pima County providers

Mercy Care is proud to continue serving ALTCS, DDD and Mercy Care Advantage (MCA) members in Pima County. Mercy Care is experiencing a high volume of inquiries from members in Pima County who are enrolled in DDD, ALTCS and Mercy Care Advantage (MCA). These members are stating that their providers are informing them of contracting changes related to the AHCCCS Complete Care contract. Please note: the 10/1 changes for the new AHCCCS Complete Care (ACC) program do not impact current DDD, ALTCS and MCA members in any GSA. Mercy Care remains contracted with AHCCCS to provide services to members enrolled in ALTCS, DDD and MCA. If you have any questions please contact your Provider Relations Representative.
