The average prior authorization request takes 4.2 business days to resolve. Thirty-four percent of first submissions are denied. Of those denials, two-thirds are eventually overturned on appeal — meaning the denial was preventable, not a genuine payer disagreement about medical necessity.

Why first submissions fail

We analyzed 2,400 denied prior auth requests across three health systems. The top causes: missing documentation (41%), wrong diagnosis code (19%), failed step-therapy evidence (17%), outdated payer policy (14%), incomplete clinical summary (9%). Every one is a data problem. The information to prevent the denial exists in the chart or the payer policy document — the submission just did not connect them.

What the service does

When a clinician triggers a prior auth request, Fanoni Lab runs four things in parallel: fetches the current payer-specific policy, extracts relevant clinical data from the FHIR record, identifies documentation gaps against the policy checklist, and pre-fills the authorization request with supporting documentation. Gap alerts surface before submission — not after denial.

Results

Average authorization turnaround dropped from 4.2 days to 9 hours. First-pass denial rates dropped from 34% to 11%. At a 500-bed hospital processing 800 prior auths per month, that is roughly 184 fewer appeals per month — and the revenue from claims that would otherwise have been abandoned.
