Fax requests for the listed hotline-authorized services (for example physical or occupational therapy visits beyond the first 12, using form F245-417-000) to this number. Utilization-reviewed services (inpatient, selected surgery, advanced imaging, spinal injections) go through Comagine Health instead. Applies to State Fund claims; self-insured employers and their third-party administrators handle their own claims in Washington. Workers' compensation: a claim number and the adjuster or injured-worker identification are usually required; coverage is determined by the claim (not by a member ID), and state fee schedules and rules govern billing.
