Built-in AI throughout the workflow
Documentation check
As you write the clinical justification, AI scans your notes against the insurer's checklist and flags missing or weak items before you submit — so you can fix gaps instead of receiving a denial.
Approval probability
After generating your justification, the form shows an AI-estimated approval likelihood based on your submission content, the insurer's known denial patterns, and your historical outcomes.
AI appeal letters
When a PA is denied, the tracking page can generate a targeted appeal letter that directly addresses the specific denial reason — pre-filling the appeal form so you can submit in one click.
PA Assistant
A conversational AI that knows every insurer's requirements, turnaround times, and common denial reasons. Ask it anything — documentation requirements, step therapy rules, appeal strategy — without leaving your dashboard.
⚠️ No Business Associate Agreement
FaxSeal does not execute Business Associate Agreements. Do not use this provider workflow for HIPAA-regulated PHI unless your organization has reviewed and approved this use without a BAA.
