Below is the list of CAS codes that are currently active in the system. Should you uncover a code on the ERA Error Report that does not appear below, please notify PatientlySpeaking of the need to activate that code. The purpose of this page is to allow you to determine which of these codes SHOULD NOT appear on the error report. Any code that you check in the Default list will not show up on any error list. Remember, checking a code here means that it WILL NOT appear on the ERA Denial Workbench or the ERA Error Workbench.
