Commission on Health and Safety and Workers' Compensation

Fraud and Illegally Uninsured Employers

CHSWC works with the California Department of Insurance (CDI) and the Fraud Assessment Commission (FAC) to improve anti-fraud efforts in the workers’ compensation system. Memoranda of Understanding (MOUs) with several agencies are used to access and match administrative data on coverage, billing and claims records with the purpose of assessing the magnitude and types of fraud in the system. Research on fraud includes pilot projects of data matching methodologies and research studies.
