Example
- REJECT-2
- Rejected; A8 / 496 / entity 85 / action U
- ACCEPT-1
- Accepted; A2 / 20 / entity PR / action WQ
Result: 1 rejected, 0 pending and 1 accepted claims.
Answer the questions this way to reach that result. Your own answers give your own.
Inputs and output
- What you enter
One or more X12 277 005010X212 or 277CA 005010X214 text files, up to 50 MB each. Files remain in the browser tab.
- What you get
- Rejected, pending and accepted counts; a rejected-first claim table with effective dates and raw codes; an X12 code-lookup link on every row; and full or redacted CSV downloads.
What this is
The reader keeps every raw category, status, entity and action code visible and puts rejected claims first.
When to use it
Use this after a clearinghouse or payer returns a claim-status file. It helps you separate rejected claims from accepted or pending work while retaining the source values needed to verify each result.
