An autonomous AI agent — acting inside payer portals, generating documents, and tracking statuses, not a chatbot — that runs the full HIPAA-compliant prior authorization cycle for a medical billing company serving 22 outpatient clinics.

The client processes roughly 1,900 prior authorization (PA) requests per month — a mandatory step where a clinic must obtain a payer's approval before performing a procedure, or the claim gets denied. A team of 11 billing specialists manually pulled patient data and procedure codes (CPT/ICD-10) from the EHR, figured out which forms a given payer required (each with its own portal and rules), filled them out, tracked status, and drafted appeals when requests were denied.

The average PA cycle took 3–5 business days, and 18% of requests stalled due to simple form errors or lack of tracking — the clinic often found out about a denial only after the procedure had already taken place.
