Monthly Enrollment Summaries
(through July 2020)

To provide more rapid insight into the impact of COVID-19 on insurance coverage in the Commonwealth, CHIA is now producing monthly enrollment data summaries by key market sectors. This new report series is in addition to CHIA's regular biannual Enrollment Trends reports.

This month’s publication includes enrollment figures through July 2020. CHIA intends to continue reporting on Massachusetts insurance coverage on a monthly basis as the impact of COVID-19 is further felt across insurance categories and market sectors.

Additionally, twice a year CHIA updates its detailed Enrollment Trends analysis for the most recent two-year period to give researchers and policymakers insight into the market. This edition covers the period between March 2018 and March 2020 and includes breakouts by payer and product type, providing a baseline for enrollment prior to the pandemic. The next Enrollment Trends publication will include detailed data through September 2020.

CHIA’s bi-annual Enrollment Trends reporting includes an interactive dashboard, a detailed databook, and technical appendix. For this reporting, coverage is defined by unique Massachusetts residents with primary, medical membership in the 12 largest commercial payers, MassHealth (Medicaid), or Medicare.

Enrollment measures are also reported in CHIA's Annual Report on the Performance of the Massachusetts Health Care System.
