UB-04 — Institutional Medical Claim: AI Extraction, Automation & Compliance
UB-04 hospital claim automation: revenue code extraction, DRG validation, and outlier detection. How Regure processes institutional claims for health insurers and workers' comp carriers.
What Is the UB-04?
Standard claim form used by hospitals, skilled nursing facilities, and institutional healthcare providers to bill insurance companies.
Market regions: US. Primary users: Health insurers, TPAs, Workers' comp carriers, Reinsurers.
Key Data Fields in the UB-04
Insurance operations need to extract and validate the following fields from every UB-04:
- Facility name and NPI
- Patient admission/discharge dates
- Diagnosis codes (ICD-10)
- Revenue codes
- DRG code
- Charges by service line
- Attending physician NPI
Manual extraction of these fields typically takes 15-45 minutes per document depending on complexity. At volume — hundreds or thousands of UB-04s per month — this creates a significant operational bottleneck and introduces transcription errors that cause downstream issues in claims, underwriting, and compliance.
Why UB-04 Automation Is Difficult
Hospital bills are complex, multi-page documents with revenue codes, service line details, and DRG groupings. Manual review takes 20-40 minutes per bill. High-value hospital claims create significant exposure if incorrectly adjudicated.
Traditional OCR tools fail on UB-04 processing because they rely on fixed template matching. When formats vary — due to different software versions, jurisdictions, carriers, or manual completion — template-based extraction breaks down. AI-powered extraction that understands document context and field semantics is required.
Regure's UB-04 Processing Capability
Regure processes UB-04 forms with revenue code mapping, DRG validation, outlier identification, and comparison against historical billing patterns. High-value bills automatically trigger independent medical review workflows.
Automation Workflows for UB-04
Regure applies the following automated workflows to every UB-04 processed:
Integration with Insurance Systems
Regure processes UB-04 documents and pushes extracted data to downstream systems via API:
- Guidewire ClaimCenter — extracted claim fields flow directly into claim records
- Applied Epic — policy data populates Epic fields automatically
- Duck Creek — underwriting and claims data syncs via Duck Creek APIs
- Sapiens — document data integrates with Sapiens CoreSuite workflows
- Any policy administration or claims system via Regure REST API
Compliance and Audit Trail for UB-04
Every UB-04 processed through Regure generates an immutable audit trail recording:
- Timestamp and source channel of document receipt
- Each field extracted and the confidence score of the extraction
- Any manual corrections made to extracted data and by whom
- Routing decisions and the rules that triggered them
- All parties who accessed the document and when
- Final disposition — filed, archived, or forwarded to downstream systems
This audit trail satisfies regulatory requirements from the FCA, EU DORA and AI Act, and US state insurance departments for evidence of controlled, documented document processing.
