High-speed ANSI 835 ERA parser extracting payer payments, deductible/coinsurance CAS adjustments, CARC/RARC codes, and PLB provider adjustments.
Quick Technical Summary: High-speed ANSI 835 ERA parser extracting payer payments, deductible/coinsurance CAS adjustments, CARC/RARC codes, and PLB provider adjustments. Implementation conforms to ANSI ASC X12 Standards (005010).
Specification & Structural Breakdown
The ANSI X12 835 is the HIPAA standard for Electronic Remittance Advice (ERA), providing detailed payment, denial, and adjustment data from payers to providers.
Parses BPR financial information including payment method (ACH, Check), total paid amount, routing/EFT trace numbers, and effective payment dates.
Extracts Claim Payment Information (CLP) and Claim Adjustment (CAS) segments containing Claim Adjustment Reason Codes (CARC) and Remittance Advice Remark Codes (RARC).
| Segment | Description | Key Elements Extracted | Usage |
|---|---|---|---|
| BPR | Financial Information | BPR01 (Trans Code: I), BPR02 (Total Paid), BPR04 (Payment Method: ACH/CHK) | Check/EFT header |
| TRN | Reassociation Trace Number | TRN02 (Check/EFT Trace #), TRN03 (Payer Tax ID) | Bank reconciliation |
| CLP | Claim Payment Information | CLP01 (Claim ID), CLP02 (Status: 1=Primary, 2=Secondary, 4=Denial), CLP03 (Billed), CLP04 (Paid) | Claim reconciliation |
| CAS | Claim Adjustment | CAS01 (Group: CO/PR/OA/CR), CAS02 (CARC Code), CAS03 (Adjustment Amount) | Patient liability & write-offs |
| PLB | Provider Level Adjustment | PLB01 (Provider ID), PLB03-1 (Reason Code: WO/CS/FB), PLB04 (Amount) | Withholding & balance forward |
