UC San Diego Health Accountable Care Network

A Medicare Shared Savings Program Accountable Care Organization

UC San Diego Health Accountable Care Network is a Medicare Shared Savings Program (MSSP) Accountable Care Organization (ACO). More specifically, this MSSP ACO is a Track 1+, and includes UC San Diego Health faculty and facilities, community hospitals, and community primary care providers and specialists serving more than 30,000 beneficiaries in San Diego, Riverside and Imperial Counties.


The UC San Diego Health Accountable Care Network supports the CMS three-part aim of improving patient experience of care, improving the health of populations, and providing more efficient and effective care. The ACO leverages our experienced integrated care teams to deliver high-quality, value-based care with support from regional hospitals and community physician practices.

Background on the Formation of the UC San Diego Health Accountable Care Network

The formation of UC San Diego Health Accountable Care Network (ACO) follows the successful development of UC San Diego Health Physician Network, a clinically integrated network. In 2014, UC San Diego Health began formally integrating with community physicians and local hospitals, collaborating on administrative functions, business and clinical initiatives to improve efficiencies and benefit patients.  Today, UC San Diego Health is aligned with Tri-City Medical center in Oceanside, El Centro Regional Medical Center in El Centro, and more than 250 select community physicians and specialists from San Diego, Imperial, and Riverside Counties. 

These partnerships support acute in-patient care and a spectrum of outpatient primary and specialty medical and surgical services, including ambulatory and emergency patient care. 

Similar to the development of the Physician Network, UC San Diego Health established extensive qualifying parameters for its selection of providers into the Accountable Care Network. Accountable Care Network participants meet high standards for patient care, patient satisfaction, and commitment to reporting on quality measures and patient outcomes. 

Accountable Care Network Participants agree to:

  • Actively participate in the ACO’s governance committees and partnership with our staff.
  • Regularly attend Quality Committee meetings, and periodic specialty area subgroup meetings to review and develop quality measures and protocols.
  • Continually monitor best practice care protocols and patient experience.
  • Use a federally certified EMR system and actively share population health information from their EMR to support patient care.
  • Meet and comply with our data-sharing requirements and quality reporting initiatives.
