The AHCCCS Solutions Center (ASC) will be temporarily unavailable on Sunday, November 8, from 3:00 AM to 9:00 AM Arizona Time due to a planned system upgrade. During this time, users will be unable to access the ASC. We apologize for any inconvenience and appreciate your patience as we complete these system improvements.
The Encounter Manual is a reference guide for Contractors outlining how to submit and correct encounter data to AHCCCS Administration.
Encounter Unit staff are available Monday through Friday (excluding State holidays) to assist contractors in resolving encounter errors or to research specific encounter issues. Questions regarding the EDI Portal should be submitted to servicedesk@azahcccs.gov. All other encounter questions, including those concerning mainframe, should be sent to AHCCCSEncounters@azahcccs.gov.
