The bill introduces a new chapter titled "Mental Health Service Provider Compensation Act" to Title 27 of the General Laws, focusing on the regulation of insurance reimbursement rates for mental health services. It defines key terms and grants the health insurance commissioner the authority to set minimum reimbursement rates, limit co-payments and prior authorization requirements, and enforce compliance through various measures, including civil penalties. The reimbursement rates are to be determined based on the mean rate paid in Massachusetts and Connecticut or 150% of the Medicare reimbursement rate for equivalent services.

The bill also allows for civil actions by aggrieved persons, the attorney general, or a representative of the office of mental health advocate to enforce the provisions of the chapter, with the possibility of recovering triple damages, attorneys' fees, and costs. It specifies that the commissioner's final orders are enforceable and subject to judicial review. The bill includes a severability clause to maintain the validity of the remaining provisions if any part is held invalid and is set to take effect upon passage. There are no specific insertions or deletions from current law indicated in the summary provided.
