Please Note: Beginning with this release, the MA APCD releases will now be named based on the most recent release year covered. This release is now referred to as MA APCD CY 2020 (2016 – 2020 data with a six-month run out). CHIA will no longer assign a number to the annual releases. Previous release names will not be changed.
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’s APCD annual releases contain five years’ worth of claims. To ensure completeness of the data set, CHIA includes claims submitted during the first six months of the current year that relate to services provided during the five-year release period. CHIA refers to this six-month period as the “run-out period.” For example, MA APCD Calendar Year 2020 includes claims, eligibility, provider, and other required file types submitted for calendar years 2016-2020, plus claims related to services provided in those years that are processed between January and June 2021.
