SIEDRS (pronounced "ciders") is a computer system developed by L&I to receive and store self-insured claim data.

• SIEDRS doesn't replace any existing processes relating to claim adjudication or reporting requirements.
• Self-insurers must continue to send all claim paperwork to L&I.

SIEDRS allows L&I to compile more data on self-insured claims, especially in the areas of claim payments, claim costs, and injury information for medical-only claims.

This data, and other self-insured claim information from L&I systems, is used to create the SIEDRS Reports. L&I publishes these reports quarterly.

The SIEDRS reports provide L&I with data to better answer questions about the performance of the self-insured community as a whole.

Self-insurers can also use these reports to compare their own workers' compensation data against the overall performance of the Washington State self-insured community.
