Claim denied.
Reason code read.
Nobody has touched it in 11 days.
- Denial queues grow faster than RCM teams can work them — each denial requires a biller to read the reason code, determine the corrective action, gather documentation, and resubmit or appeal. At scale, the queue is permanent.
- Appealable denials have strict timely filing windows — typically 30 to 180 days depending on the payer. Every day a denial sits unworked is a day closer to the window closing and the revenue becoming unrecoverable.
- High-volume denial codes — CO-4 modifier errors, CO-96 non-covered charges, CO-97 bundling — follow a defined remediation pattern every time. The biller who works them is executing a rule, not making a decision.
The denial arrives. It enters the denial queue. The RCM team reviews the queue in priority order — high-dollar claims first, oldest first. The $400 claim denied for a CO-4 modifier error waits eleven days before a biller opens it.
The biller reads the denial, identifies the correct modifier, corrects the claim, and resubmits. Twelve days from denial to resubmission. The payer's timely filing clock has been running the entire time.
The denial arrives. The AI agent reads the reason code — CO-4, modifier invalid — identifies the correct modifier for the procedure, corrects the claim, and resubmits. Time from denial to corrected resubmission: same day.
For denials requiring clinical documentation or appeal letters, the agent identifies the documentation required, requests it from the clinical team, assembles the appeal package, and submits. The RCM team is notified only when a denial falls outside defined resolution authority.
What AI agents resolve
across your denial queue.
| Denial Type | What the AI Agent Does | Outcome |
|---|---|---|
| Modifier and coding errors (CO-4, CO-5) | Reads the denial code, identifies the correct modifier or code, corrects the claim, and resubmits. For recurring patterns, flags the source billing rule for correction to prevent recurrence. | Modifier denial resubmission cycle drops from 8–14 days to same-day. Recurring modifier errors identified and addressed at source. |
| Medical necessity denials | Reads the denial, identifies the clinical documentation required to support medical necessity, requests it from the clinical team, and submits the appeal with the supporting documentation. | Appealable medical necessity denials enter the appeal workflow within 24 hours. Denial overturn rates improve. |
| Duplicate claim denials (CO-18) | Identifies whether the denial is a true duplicate or a system error. For system errors, corrects and resubmits. For true duplicates, closes the claim with a complete audit record. | Duplicate denial queue cleared without biller involvement. True duplicates documented and closed. System-error duplicates corrected same-day. |
| Timely filing denials | Monitors denial queue for timely filing risk — claims approaching appeal windows. Surfaces them for priority handling before the window closes, with the current status and days remaining. | Revenue lost to missed timely filing windows substantially reduced. RCM team focuses on strategic appeals, not calendar management. |
| Payer-specific denial patterns | Identifies recurring denial patterns by payer and code. Applies payer-specific remediation rules for standard denial types. Escalates non-standard denials with full context and recommended action. | Payer-specific denial patterns resolved systematically. RCM team reviews exceptions, not queues. |
When an AI agent corrects a claim and resubmits on your behalf, the billing compliance record must show exactly what was changed, what the denial reason was, and what authority the correction was made under. If a payer audits the resubmission or a patient disputes the outcome, you need that record without reconstructing it from email threads.
PLRX logs every agent action on every denial. Every denial received, every reason code read, every correction applied, every resubmission made — captured in a structured, timestamped record. Queryable by claim number, by denial code, by payer, by date. If an auditor asks for the complete denial management record for a billing period, it exports directly.
The record distinguishes between corrections the agent made autonomously and escalations the agent surfaced to the billing team. Both are logged. The authority boundary is explicit and auditable — not inferred from agent behavior.
Your RCM team didn't sign up to work a denial queue that grows faster than they can clear it.
PLRX AI agents work your denial queue continuously — reading reason codes, correcting standard denial types same-day, assembling appeal packages, and escalating only the denials that require billing judgment. The queue shrinks. The timely filing windows stay open.
