Workers' Compensation for Insurers

Workers’ compensation insurers can learn about assessments, batch claims, and our document management system.

Insurers can find out how assessments are calculated, pay their assessment fees online, and sign up for Electronic Data Interchange (EDI). They also can learn how the batch claim system and the document management system (DMS) work.
