Menu guidance in the source record

For help submitting authorizations or using ProAuth: prompt 7, then prompt 2.

Menus can change. No live call verification is claimed.

ProAuth is the preferred submission method. The March 14, 2026 training deck says to use 508-368-9700 if instructed to fax a request. The FAQ also identifies it for supporting documents when portal attachments are blocked. Inpatient notifications, facility levels of care and delegated services have different instructions. The inherited urgent-care fax was not reverified and is omitted.
