Submission Deadline

  • These reports are due by September 25, 2024.


In 2022, Massachusetts enacted Chapter 177: An Act Addressing Barriers to Care for Mental Health, charging CHIA with monitoring “costs, cost trends, price, quality, utilization, and patient outcomes related to behavioral health service subcategories.” Behavioral health service subcategories include, but are not limited to: mental health, substance use disorder, outpatient, inpatient, services for children, services for adults, and provider types as defined in M.G.L. c. 12C, § 10 Section 21A. Chapter 177 requires CHIA to publish information that separately measures mental health and substance use disorders across specific settings and populations.

Payers must submit data to CHIA annually in accordance with regulation 957 CMR 2.00.  This regulation governs the methodology and filing requirements for health care payers to calculate and report Primary Care & Behavioral Health Expenditures.

The listening session focused on the following topics related to the draft data specifications:

  • Review proposed measurement approach;
  • Solicit feedback from stakeholders about existing approaches to classifying provider and service types;
