Wisconsin Statutes Employment, Compensation and Mining (Ch. 101 to 109) § 102.125. Fraud reporting , investigation, and prosecution

(1) If an insurer or self-insured employer has evidence that a claim is false or fraudulent in violation of s. 943.395 and if the insurer or self-insured employer is satisfied that reporting the claim to the department will not impede its ability to defend the claim, the insurer or self-insured employer shall report the claim to the department. The department may require an insurer or self-insured employer to investigate an allegedly false or fraudulent claim and may provide the insurer or self-insured employer with any records of the department relating to that claim. An insurer or self-insured employer that investigates a claim under this subsection shall report on the results of that investigation to the department.

(2) Assistance by department of justice. The department of workforce development may request the department of justice to assist the department of workforce development in an investigation under sub. (1) or in the investigation of any other suspected fraudulent activity on the part of an employer, employee, insurer, health care provider, or other person related to worker's compensation.

(3) Prosecution. If based on an investigation under sub. (1) or (2) the department has a reasonable basis to believe that a violation of s. 943.20, 943.38, 943.39, 943.392,943.395, 943.40, or any other criminal law has occurred, the department shall refer the results of the investigation to the department of justice or to the district attorney of the county in which the alleged violation occurred for prosecution.
