Coverage Research Service

In addition to providing self-service coverage research capabilities to the public via the Coverage Inquiry website and for insurer claims adjusters and government agencies through WCIRB Connect, the WCIRB provides coverage research service to an insurer, employer, injured worker, licensed health care provider or an attorney involved in a pending workers' compensation claim. To make a coverage research request, the requesting party must (1) certify that he/she is entitled to receive the coverage information, that the information will be used solely in connection with the pending workers' compensation claim, and that the information will not be otherwise published, distributed or released to third parties and (2) complete and submit Form 807 - Coverage Research Service Request. The form may also be used for employers requesting their own coverage information at any time.

Form Requirements

The information requested on the form is required for the WCIRB to process a request for coverage information when there is a pending claim. This includes (1) names of the parties of the pending workers’ compensation claim, (2) date of injury, (3) claim number (required on insurer requests), (4) WCAB number (if assigned and known), (5) the employer for which the information is requested, (6) the employer's address, and (7) the year(s) of coverage needed.

  • $20 per employer, per coverage year for 1996 through the present
