Chapter 152 of the General Laws of Massachusetts (the workers' compensation statute) provides that the Health Care Services Board (HCSB) of the Department of Industrial Accidents will receive and investigate complaints about health care providers from employees, employers, and insurance companies. 

The Health Care Services Board will investigate complaints to determine if health care providers have engaged in a pattern of behavior that falls into any of the following categories:

1. discrimination against people who have filed workers' compensation claims, or are receiving workers' compensation benefits;
2. over-utilization of procedures;
3. unnecessary surgery or other procedures;
4. other inappropriate treatment of workers' compensation recipients

If the Health Care Services Board finds that a provider has engaged in a pattern of behavior that fits any of the categories described above, it will refer the complaint(s) about the provider to the appropriate board of registration or other appropriate state agency.
