Your selected 835, 837, 999, and 277CA files are processed in your browser to create previews, charts, acknowledgment summaries, and Excel reports. File contents and patient-level results are not uploaded to Logic Bunting or its service providers as part of that processing workflow.

Check importer compatibility. Some EHRs accept multiple X12 interchanges in one file; others do not. No payments are posted by this tool. Select only ERAs that have not already been imported, and confirm that your destination processes every included ERA. Different files can still contain overlapping claims.

277CA Claim Results
Patient Control # acceptance/rejection is claim-level 277CA information. A 999 is transaction/file-level.

999 Transaction Results
Shows whether each acknowledged 837 transaction set passed implementation/syntax processing.

277CA Non-Claim Issues
Provider or submitter-level rejections can occur before individual Patient Control # records are returned.
| Source File | Level | Entity | Status | Reason |

Front-end acknowledgment only. A rejected 277CA claim did not enter normal adjudication and should be corrected/resubmitted as appropriate. An 835 denial is different: it reflects an adjudicated claim. Code descriptions are a convenience; payer-specific edits and unknown codes should be verified with the payer/clearinghouse or X12 reference.
Analyzed locally in your browser. Acknowledgment files, patient identifiers, and results are not uploaded to Logic Bunting.
Privacy & healthcare data
Privacy-first
Keep healthcare files where they belong.
We collect the tool used, file count, and event time, linked to your account or a browser identifier. These events do not include filenames, patient information, claim details, or report contents.
Clearing the workspace removes selected files and results from this page. It does not delete originals or downloaded workbooks. Reports may contain PHI; use organization-approved storage and sharing.
Use EEI only with healthcare records you are authorized to access, and follow your organization’s privacy and security policies. HIPAA compliance depends on your overall processes, safeguards, and use of the tool.
Billing and Account Support Only. EEI is self-service software. Support covers your Logic Bunting account and subscription billing, not file review, claim investigation, or report troubleshooting. Do not send files, screenshots, or sample data, including synthetic or de-identified examples. See our support scope.
