EDI Amount Adjuster

Audit service-line amounts in an EDI text file, preview differences, and optionally adjust the final CAS amount. Runs locally in your browser; files are not uploaded.

Select EDI file (.txt, .edi, .837)

EDI file type

Amount decimals

No file selected.

Adjustment settings

If an adjustment is needed, the tool can update the amount in the last CAS segment for that service line.

If no CAS segment exists on a mismatched service line, create one (disabled by default).

New CAS group code

New CAS reason code

I confirm the selected CAS group/reason codes are approved for this payer and adjustment scenario.

Important: Validate the file structure and payer rules with your EDI team before using adjustments in production. SV1/SV2 are 837 service-line segments, while SVD/CAS are generally associated with 835 remittance adjudication loops. The sample format may mix structures. This tool is a helper, not an X12 compliance validator.
