The Department of Health Care Services (DHCS) is advancing health information exchange and data sharing to improve the care and outcomes for Medi-Cal Members as California continues its journey into data-driven, value-based health care. Data sharing is foundational to care coordination and is essential to supporting whole-person care programs such as Enhanced Care Management, Community Supports, Population Health management, and other Medi-Cal initiatives.

This page serves as a centralized repository of data exchange and data sharing guidance and requirements to provide clarity and technical assistance to stakeholders, including Managed Care Plans, County Health and Human Services Agencies, Community-Based Organizations, and Providers. DHCS initiatives require the exchange of administrative, clinical, social, and human services information in compliance with federal and state privacy and data sharing laws, regulations, and policies.
