The HPC Accountable Care Organization (ACO) Certification Program

A program designed to accelerate care delivery transformation in Massachusetts and promote a high quality, efficient health system.

Pursuant to G.L., c. 6D, §15, the HPC is required to "establish a process for certain registered provider organizations to be certified as accountable care organizations." The purpose of the Certification program is to complement existing local and national care transformation and payment reform efforts, validate value-based care, and promote investments by payers in efficient, high-quality, and cost-effective care.

In 2016-2017, the HPC collaborated with MassHealth and other state purchasers to develop a certification program that aligns with payment reform efforts. Detailed information on the 2017 certification standards can be found in the Application Requirements and Platform User Guide (PUG).

A total of 17 ACOs achieved certification in 2017. The first round of ACO Certification marked a significant milestone in the implementation of Chapter 224, making Massachusetts the first state to implement state-wide, all-payer standards for care delivery. Certification is effective for a term of two years.  The HPC’s ACO Certification program complements its PCMH Certification program.  Questions about the ACO Certification program may be sent to HPC-Certification@mass.gov.

For 2019, the HPC is proposing some updates to ACO Certification requirements as well as a potential voluntary new Distinction program for certified ACOs, and seeks public comment on this proposal. 

A Request for Public Comment document is posted below.
