835 / ERA Decoder

Paste a de-identified 835 remittance (ERA) and decode it into readable payment, claim, adjustment, and provider-level detail — including BPR/TRN, N1/NM1, CLP, SVC, CAS, LQ, and PLB. Everything runs in your browser.

BetaBrowser-onlyNo PHIX12-based
No PHI

Do not paste patient names, Medicare IDs, SSNs, full claim files containing PHI, or other protected health information. This tool is intended for de-identified examples and educational / reconciliation support. Everything runs in your browser — nothing you paste is stored, logged, or sent anywhere. EDI is parsed entirely on this page; it never leaves your device.

Formula notes
Expected payment = total claim payments (CLP) minus net provider-level adjustments (PLB); a positive PLB amount reduces the deposit.
Known exclusions
  • Not a certified X12 validator — loop, qualifier, and implementation-guide rules are not fully enforced
  • Individual CARC / RARC code meanings are shown by code only (a separate lookup, not loaded here)
  • Payer-specific posting and adjustment rules vary
  • Sequestration, interest, and recoupment may appear as CAS or PLB depending on the payer
Browser-onlyNo PHI

De-identified examples only. Reconcile against the official remittance and your deposit before posting. Nothing you paste is stored, logged, or transmitted.

Paste 835 / ERA

This is a practical decoder, not a certified X12 validator. It reads the common segments listed above and balances the file at a high level; it does not validate every loop, qualifier, or implementation-guide rule. Claim adjustment group codes (CO/PR/OA/PI/CR) and a seed set of PLB reason codes are described, but individual CARC and RARC code meanings are shown by code only — a dedicated CARC / RARC lookup is a separate tool. Always reconcile against the official remittance and your deposit before posting.
