The July 2015 edition of the Massachusetts Health Care Coverage: Enrollment Trends, offers new insights into changes in health insurance coverage through the second Affordable Care Act Open Enrollment period in Massachusetts. Coverage is defined by unique Massachusetts residents in primary, medical membership within the top 16 commercial payers and, to the extent data allow, within MassHealth (Medicaid) and Medicare.

Key Findings from July 2015 Enrollment Trends include: 
• Total non-Medicare market membership remained steady (+1%) between March 2014 and March 2015, although it declined slightly (-2%) between December 2014 and March 2015 after temporarily peaking.
• From December 2014 to March 2015, as three of Massachusetts public programs closed (MassHealth Transitional, Commonwealth Care, and the Medical Security Program), commercial membership increased by +117,000 enrollees (+3%), 72% of which was subsidized enrollment, and MassHealth Direct membership increased by +119,000 enrollees (+10%).

The July 2015 edition of the Enrollment Trends, includes a brief, infographic, databook, and technical notes. These resources and more information are available at The databook presents commercial and public enrollment by payer for the period of March 2014 to March 2015. Commercial enrollment is available by funding type (fully- or self-insured), product type (e.g., HMO, PPO), and market sector (employer group size). The databook contains data tables and visuals.

Enrollment Trends is produced using the Massachusetts All Payer Claims Database (MA APCD), supplemented with payer-reported data (where needed), and data from MassHealth, the Massachusetts Health Connector, and the Centers for Medicare and Medicaid Services (CMS).
