Case Study: L.A. Care Health Plan achieves 95% provider data quality and stronger PHI/PII privacy with Informatica's integrated data governance solution

Improving Provider Data and Patient Privacy at L.A. Care Health Plan

L.A. Care Health Plan, one of the largest publicly operated health plans in the U.S. serving nearly 2.2 million members in Los Angeles County, faced rapid eight-fold growth after the ACA and struggled with fragmented IT silos, poor incoming provider data (often below 30% quality), and limited visibility into PHI/PII lineage and regulatory traceability—creating compliance, security, and analytics challenges.

Using an integrated Informatica solution (Axon, Enterprise Data Catalog, Data Quality, PowerCenter and MDM), L.A. Care automated discovery and cataloging of PHI/PII, applied more than 2,200 data-quality rules across nine dimensions, and linked regulations to policies and data rules for instant traceability. The initiative raised provider data quality to about 95%, strengthened HIPAA compliance and privacy controls, accelerated regulatory change management, and delivered trusted data for operations, reporting, and population-health analytics.
