What Is an X12 835 File?
The 835 is the ANSI X12 transaction set a payer sends back to a provider to explain how a claim (or batch of claims) was paid or denied — it's the electronic equivalent of an Explanation of Benefits. It carries payment amounts, claim adjustment reason codes (CARC), remittance advice remark codes (RARC), and references back to the original claim, letting billing staff reconcile exactly what was paid, adjusted, or denied and why.

Why Convert an 835 to CSV?
Payment reconciliation is fundamentally a matching exercise — matching what was billed (837) against what was paid (835). CSV is the lowest-friction format for this: it opens instantly in Excel or Google Sheets, imports cleanly into accounting software, and works with simple VLOOKUP/XLOOKUP formulas to match claim numbers between your 837 and 835 exports.
Key Segments You'll See in an 835 Export
- BPR — Financial Information: total payment amount and payment method.
- CLP — Claim Payment Information: claim status, charge amount, paid amount, patient responsibility.
- CAS — Claim Adjustment: reason codes explaining any reduction from the billed amount.
- SVC — Service Payment Information: line-level paid amounts.
- PLB — Provider Level Adjustment: adjustments not tied to a specific claim.

Frequently Asked Questions
What's the difference between an 835 and an 837?
The 837 is the claim submitted by the provider; the 835 is the payer's response explaining how that claim was paid or adjusted.
Can I see claim adjustment reason codes (CARC) in the export?
Yes — CAS segments (which carry adjustment reason codes) are parsed and labeled like every other segment in the file.
Is my remittance file uploaded anywhere?
No. Parsing happens entirely in your browser; the file is never transmitted to a server.
Is this a subscription?
No — a one-time payment (currently 50% off at $29.99) unlocks unlimited full-file exports, with no recurring fees.
Does this support both 4010 and 5010 versions, and can I batch-convert multiple files?
Yes on versions — the parser reads structurally from the file's own delimiters, so 4010, 5010, and other X12 versions of the 835 all work. It currently processes one file at a time; there's no bulk/batch upload feature yet. It runs on any device with a modern browser, including Mac and Chromebook.
