This document is California worker's compensation department's revised manual on EDI implementation guide for first and subsequent reports of injury.
This document provides step-by-step instructions for claims administrators to submit First and Subsequent Reports of Injury via Electronic Data Interchange (EDI) to California’s Workers’ Compensation Information System (WCIS). It covers data elements, transaction sequencing, system specifications, and legal requirements. The guide is designed for both experienced EDI users and new organizations, with sections on implementation, testing, and contact resources.
The guide references California’s statutory requirements under Labor Code sections 138.6 and 138.7, outlines data transmission via SFTP (SSH), and includes appendices detailing version updates and code lists for injury, body part, and benefit types.
| Data Transmission Method | SFTP (SSH File Transfer Protocol) |
|---|---|
| First Report Deadline | 10 business days after knowledge of claim |
| Subsequent Report Deadline | 15 business days after benefit change or event |
| Medical Bill Reporting Deadline | 90 calendar days from payment or final determination |
| Annual Summary Deadline | January 31 |
First Reports of Injury must be submitted by EDI no later than 10 business days after the claim administrator knows of the claim.
Data are transmitted via SFTP (SSH File Transfer Protocol).
This guide is intended to be a primary resource for claims administrators to understand and comply with California’s EDI reporting requirements for injury reports.
Claims administrators — insurers, self-insured employers, and third-party administrators — are required to submit EDI reports.
