The Massachusetts APCD is the most comprehensive source of health claims data from public and private payers providing insurance to Massachusetts residents and employees.
The claims data sets sent to CHIA cover a number of services, including: medical, pharmacy, dental, vision, behavioral health and specialty services. Submitters also send detailed files on their insurance products, affiliated providers and benefit plans.
Please visit CHIA’s Regulations page for more detailed information on who is required to submit data and what data they must submit.
Health plans, researchers, and others use the MA APCD to analyze and report on population health management, quality outcomes, costs and pricing variations. To learn more about how MA APCD data is used, view historical applications for data that CHIA has received from researchers and other entities. You can also review a sample of both internal and external research using MA APCD and Case Mix data.

CHIA refers to this six-month period as the “run-out period.” For example, MA APCD Calendar Year 2021 includes claims, eligibility, provider, and other required file types submitted for calendar years 2017-2021, plus claims related to services provided in those years that are processed between January and June 2022.
