What telephone and fax number will I use to contact ACS? And what address will I use to send Retrospective reviews?
To make the transition easier for the provider community, ACS will retain the same toll free phone number, (800) 766-0686, and fax number, (573) 634-4262, used by HCE. The phones are staffed from 8 am to 5 pm, Monday Friday, except for holidays. If providers call during off hours or the line is busy, you may leave a message and ACS will return your call by the next business day.
