California Health Data Utility Manifest MedEx’s Increasing Role in Public Health

In 2022 MX began supporting the California Department of Public Health with the infrastructure required to enable statewide electronic lab reporting

During a WEDI 2025 Spring Conference panel session, Erica Galvez, CEO of Manifest MedEx (MX), highlighted several ways the health data utility (HDU) is partnering with state and local public health agencies in California to improve population health.

Galvez was speaking on a panel with two other leaders of the HDU movement: John Kansky, president and CEO of the Indiana Health Information Exchange, and Melissa Kotrys, CEO of Contexture, the health data organization for Colorado and Arizona. All three are members of the Consortium for State and Regional Interoperability (CSRI), along with CRISP, CyncHealth, and the New York eHealth Collaborative. CSRI defines the health data utility (HDU) as a single organization or a jointly governed cooperative of a small number of organizations, ideally operated by a not-for-profit organization with multi-stakeholder governance, that seeks to meet the comprehensive health data and health data analytics needs of both the public and private sectors within a state.

In California, MX is a statewide health data utility connected to 19 health plans, over 140 hospitals, approximately 3,000 providers, with 40 million people in the master person index.

Saying that she sees population health as a foundational characteristic of health data utilities, Galvez began her WEDI presentation by talking about an example involving statewide electronic lab reporting and case reporting. In 2022 MX began supporting the California Department of Public Health (CDPH) with the infrastructure required to enable statewide electronic lab reporting.
