MassHealth Accountable Care Organizations (ACOs)

What is an ACO?

An ACO is a provider-led entity (e.g., a group of providers or a health system) that coordinates care, has an enhanced role for primary care, and is rewarded for value—improving total cost of care and outcomes—not volume. An ACO is expected to deliver a more integrated and improved member experience and have flexibility to engage members differently (e.g., enhanced services, care coordination).

What is the role of a health plan in an ACO?

The health plan (i.e., Fallon Health) pays claims and partners with the provider group to improve care delivery and to support integration of care. The partnership between the health plan and the provider group allows additional support, increased capacity, and improved analytics for population health management.
