What AI denial management actually does
AI denial management software reads the denial codes on your remittances (the CARC and RARC codes in 835 files or EOBs), works out why each claim was denied, prepares the fix, and tracks it to payment. It replaces the spreadsheets, payer portals and copy-paste letters that billers use to work denials by hand.
Most small practices don't have time to work every denial, so smaller ones get written off. An agent doesn't triage by size: it works them all, with your approval before anything goes to a payer.

Plugs into your remits
Connect your clearinghouse or drop in ERAs and EOBs. Every denial and short-payment surfaces on its own, no spreadsheet required.

Finds the real reason
It reads the CARC and RARC codes against the claim and the payer's rules, and pinpoints exactly what went wrong and what fixes it.

Chases it until you're paid

How it compares
The four ways a practice can handle denials, and who each one fits.
| Approach | Who does the work | How you pay | Best fit |
|---|---|---|---|
| Working denials in-house | Your biller or front desk, by hand | Staff time; small denials often go unworked | Practices with spare billing capacity |
| Outsourced billing or denial service | An external team | Often priced as a percentage of collections | Practices that want to hand billing off entirely |
| Enterprise denial management software | Your team, using analytics and workflow tools | Contracts sized for hospitals and large groups | Health systems with revenue cycle teams |
| Undeny (AI agent) | The agent drafts, files and follows up; you approve | Flat monthly pricing, never a cut of collections | Small therapy and outpatient practices |
The denials it works

What is AI denial management?
AI denial management uses AI to do the work of working a denied claim: reading the denial codes on the remittance, finding the root cause, preparing the appeal or corrected claim, filing it, and tracking it until the payer pays or a deadline is reached. Undeny does this as an agent and asks for your approval before anything is sent.
How is Undeny different from a billing company?
A billing company does the work with its own staff and is often paid a percentage of what it collects. Undeny is software: an AI agent that works every denial for your team at a flat monthly price, and your team approves each submission.
Which denials can the agent handle?
The common ones that small practices see: bundling and modifier denials, missing authorizations, medical necessity, timely filing, coordination of benefits, frequency limits and underpayments. It applies each payer's own appeal levels and deadlines.
Is it available now?
The agent is in early access. We're onboarding the Founding 100 first, in the order practices join, with a free denial audit at launch. The appeal letter generator and billing tools are free to use today.
How does it handle patient information?
The agent will handle PHI only under signed Business Associate Agreements, on zero-data-retention AI endpoints, and nothing is sent to a payer without your approval. Today's free tools are designed not to need PHI.
