Find denials in your 835 files
See every denied claim and service line in an 835 with its CARC reason, group code and RARC remarks, plus a summary of dollars by reason code. Free to view, nothing uploaded.
How Remitgrid flags a denial
- Claims with status code 4 (denied).
- Claims paid $0 where nothing was moved to the patient and the charge was adjusted off (excluding reversals and claims forwarded to another payer).
- Service lines paid $0 with no patient responsibility on an otherwise paid claim.
Use the Show: Denied filter above, or the Denials & adjustments by reason table to see which reasons cost the most. Pro exports a denials worklist with patient, claim number, dates, procedure, reason and remark codes for follow-up.
Look up any code in our CARC and RARC code list, and see what CO, PR, OA and PI mean.
Private by design
An 835 is full of protected health information — patient names, member IDs, dates of service and procedure codes. Remitgrid reads the file with JavaScript in your browser tab. The contents are never uploaded, logged or stored, and nothing is saved when you close the tab. You can confirm it in your browser's developer tools (Network tab), or disconnect from the internet after the page loads and keep working.
How it works
- Download the 835 (ERA) from your clearinghouse, payer portal or practice-management system.
- Drop it here. Payments, claims and lines appear instantly, with balancing checks and denials flagged.
- Export claims or service lines to CSV, print a readable remit, or (Pro) download the Excel workbook and denials worklist.
FAQ
Is my 835 uploaded?
No. The file is read by JavaScript running in your browser tab; its contents — patient names, member IDs, claims — are never sent over the network or stored. You can verify this in your browser's developer tools (Network tab), or go offline after the page loads.
Is it HIPAA compliant?
Remitgrid never receives, stores or transmits your files, so no PHI reaches us. HIPAA compliance depends on how your organization handles the files and anything you download — use approved devices and storage, and check with your privacy or compliance officer.
Which files work?
X12 835 health care claim payment/advice files (version 005010X221A1 and most older ones), usually named .835, .edi, .txt, .era or .x12. Files with several payments, any delimiters, and with or without line breaks are supported. 837, 277 and 999 files are recognised and politely refused.
What do the balancing checks do?
For every service line, claim and payment, Remitgrid checks that billed − adjustments = paid, and that claims paid − provider-level adjustments = the check or EFT amount. It also checks segment counts and control numbers. Anything that doesn't add up is marked UNVERIFIED.
Are the code descriptions official?
No. They are short plain-English summaries written by Remitgrid. The official CARC and RARC wording is published by X12 at x12.org/codes, and payers apply codes according to their own policies.
What's free?
Viewing any 835 of any size, the balancing checks, denials view and reason summary are free. Claims and service-line CSVs and printing are free for files up to 50 claims. Pro removes the limit, opens many files at once, and adds the Excel workbook, denials worklist, adjustments and patient-balance CSVs.
