UC16: Denial Management & Appeal Generation

The Problem

Hospitals lose 3 to 5% of net revenue to denials that are never appealed. The average cost to rework a denied claim is $25 to $118, yet many denials contain appealable denials based on incomplete documentation or payer error. Manual denial triage is slow and inconsistent; appeals are often missed entirely due to time-sensitive deadlines.

What the Agent Does

Categorises incoming 835 ERA denials by CARC/RARC code and payer contractual rules
Automatically fetches supporting clinical documentation from the EHR (clinical notes, labs, imaging reports)
Drafts payer-specific appeal letters citing contract terms, medical necessity, or compliance violations
Tracks appeal submission deadlines and re-submission status across payers
Generates denial trend reports by CPT code, diagnosis, and payer to identify systemic issues

Data Requirements

Data Sources:

Payer 835 ERA Systems , Denial codes (CARC, RARC), claim-level remittance data, payer contact rules
Epic/Cerner/Meditech , Clinical documentation (notes, labs, imaging reports), claim submission details
Waystar/R1 RCM , Claim history, payer contracts, prior appeal outcomes
Internal Finance , Claim amounts, contract fee schedules, appeal thresholds

Data Classification:

Epic/Cerner/Meditech: Internal, Structured & Unstructured (clinical notes, labs)
835 ERA: External, Structured
Contract data: Sensitive, Internal, Structured

Data Quality Requirements:

ERA data timeliness: same-day or next-business-day from payers (EDI standard)
Clinical documentation completeness: all claims must have corresponding clinical records within 30 days of service
Contract data accuracy: must be updated within 7 days of execution

Integration Complexity: Medium

835 EDI parsing and CARC code taxonomy required
EHR API integration (Epic FHIR, Cerner REST) for documentation retrieval
Payer contract terms database normalisation
Appeal letter template management and payer-specific address routing

Why It Scores Well

Denial management is mission-critical: even a 0.5% improvement in appeal success saves a 500-bed hospital $2 to 3M annually. The data is highly structured (ERA codes, contract terms), mature payer integration standards exist (X12 835), and appeal success is easily measurable. This use case directly reduces revenue leakage.

Regulatory Alignment

HIPAA: Clinical documentation must be de-identified in shared appeal letters where permitted; PHI storage must comply with access controls
CMS: Appeal timelines vary by payer; CMS Medicare secondary payor (MSP) rules require specific documentation
State Laws: Some states (e.g., California) mandate timely appeal notification; timeline varies by payer contract

Sprint Factory Fit

Sprint 0 (2 weeks) + 4 build sprints (8 weeks)

This use case fits the Sprint Factory model well: denial data arrives continuously (event-driven), agent logic is deterministic (rule-based), and outcomes are quantifiable (appeal approval rate). The initial 2-week sprint focuses on ERA parsing and contract term mapping; subsequent 2-week sprints add payer-specific appeal templates, EHR integration, and outcome tracking.
