Massachusetts offers robust consumer protections through its Division of Insurance, the Office of Patient Protection for binding external review, and the MHEAR Act — one of the strongest mental health parity laws in the nation.
Massachusetts regulates insurance through the Division of Insurance (DOI), which handles consumer complaints, licenses insurers, and enforces regulations. The Office of Patient Protection (OPP), part of the Health Policy Commission, administers binding external reviews for medical necessity denials. DOI's Consumer Service Unit responds to complaints within 30 days and can order corrective action against insurers that violate state law. You can reach OPP at (800) 436-7757.
Under Chapter 176O, after exhausting internal grievance, you can request external review through OPP within 4 months of your final adverse determination. An independent physician — with no ties to your insurer — reviews your case. The decision is legally binding on your insurer. Standard reviews are completed within 45 days; expedited reviews for urgent medical situations within 72 hours. This process is free for consumers and available for all fully-insured health plans.
Internal grievance: Your insurer must resolve within 30 business days (48 hours for urgent cases, 5 days for terminal illness). After denial, you have 4 months to request OPP external review. Standard external review takes up to 45 days. Expedited external review for urgent situations: 72 hours. DOI complaint investigations require the insurer to respond within 30 days. Carriers must notify you within 2 days of modifying or denying a request.
The MHEAR Act (Mental Health Equitable Access and Rights), effective January 2025, is one of the strongest mental health parity laws in the nation — no fees for external reviews, and insurers cannot raise premiums based on review usage. Massachusetts also mandates coverage for infertility treatment including IVF, autism services including ABA therapy, and substance use disorders. Chapter 176O guarantees the right to designate representatives in grievance proceedings.
Three steps. No jargon. No legal degree required.
In Massachusetts, first file an internal grievance with your insurer under Chapter 176O. Your insurer must respond within 30 business days (48 hours for urgent cases, 5 days for terminal illness). If denied again, you can request an external review through the Office of Patient Protection (OPP) within 4 months of the final adverse determination. An independent physician reviews your case and issues a binding decision within 45 days.
The Office of Patient Protection (OPP), part of the Health Policy Commission, administers the external review process for health insurance denials based on medical necessity. An independent doctor — with no ties to your insurer — reviews your case and issues a binding decision. OPP also monitors carrier denial trends and can refer patterns of improper denials to the Division of Insurance or Attorney General for investigation. You can reach OPP at (800) 436-7757.
The Mental Health Equitable Access and Rights (MHEAR) Act took full effect in January 2025. It is one of the strongest mental health parity laws in the nation. It ensures patients cannot be charged any fees for external reviews of mental health denials and prohibits insurers from raising premiums based on external review usage. It also requires insurers to report annually on mental health parity compliance.
Internal grievances must be resolved within 30 business days (48 hours for urgent cases, 5 days for terminal illness). You have 4 months from your final adverse determination to request external review through OPP. Standard external reviews are decided within 45 days. Expedited external reviews for urgent medical situations are decided within 72 hours. The Division of Insurance complaint process requires insurers to respond within 30 days.
