Data Exchange Framework

The Data Exchange Framework (DxF) is an opportunity to create equitable and affordable health information exchange, so that patients, providers, and other healthcare entities can access the health information they need, wherever they are and whenever they need it.

The DxF DSA Signing Portal is now open for providers and healthcare entities to take the first step for better health information exchange. The DSA is a signed agreement between hospitals, physician organizations and medical groups, skilled nursing facilities, health plans and disability insurers, clinical laboratories, and acute psychiatric hospitals to share patient information safely.

California Health and Safety code requires most providers and healthcare entities to sign the DSA by January 31, 2023.

Take the first step today. Visit the CalHHS Data Sharing Agreement Signing Portal to sign the DSA.
