Atrius Health

Atrius Health is a Massachusetts based healthcare organization acquired by Optum on May 31, 2022. Atrius Health has a system of connected care for adult and pediatric patients in eastern and central Massachusetts. Atrius Health's medical practices work together with the home health and hospice services of its VNA Care subsidiary and in collaboration with hospital partners, community specialists and skilled nursing facilities.

The Atrius Health groups operate as a model for accountable care organizations (ACOs) with responsibility for the quality and cost of care for many of their patients since before the term was coined by Elliott S. Fisher in 2006. In 2009, Atrius Health became one of the first organizations to sign on to the Blue Cross Blue Shield of Massachusetts Alternative Quality Contract (AQC).

Atrius Health is also a participant in the Centers for Medicare & Medicaid Services' Pioneer ACO program. In 2015, Atrius Health's Pioneer ACO's quality scores were the highest among Pioneer ACO's in Massachusetts and the third-highest among Pioneer ACOs nationally.

Atrius Health has also earned Stage 7 recognition from HIMSS Analytics, the highest level possible nationally for the use of health information technology.
