The Data Exchange Framework: the California deadline most independents missed two years ago

What the DxF actually is

AB 133, the 2021 health-omnibus trailer bill, set up the Data Exchange Framework. It is a statewide framework that requires health and social-services providers to exchange patient information in real time. The framework has three pieces. A single statewide Data Sharing Agreement (the DSA), a common set of Policies and Procedures, and a network of Qualified Health Information Organizations (QHIOs) that handle the technical exchange.

Administration moved from CalHHS's Center for Data Insights and Innovation (CDII) to the Department of Health Care Access and Information (HCAI) in August 2025. The portal at dxf.chhs.ca.gov remains the authoritative entry point.

Who has to sign, and by when

Skilled nursing facilities (as defined in Health and Safety Code section 1250(c)) that maintain electronic health information are mandatory signatories. Paper-only SNFs are exempt from the signing requirement but are encouraged to participate.

Hospitals, physician organizations, health plans, and clinical labs had to sign by January 31, 2023. SNFs and other smaller entities had until January 31, 2024 to sign and begin real-time exchange. A final extension carried some smaller and rural entities into January 31, 2026. If you have not signed and you maintain any electronic records, you are past due.

Why this is suddenly urgent

Two things changed in 2025 that pulled enforcement closer for independents. First, the framework's administration moved to HCAI, which sits closer to the licensing apparatus that already touches SNFs. Second, several Medi-Cal managed care plans have signaled that DxF participation will become a contract condition. A plan can decline to renew your network agreement if you have not signed the DSA.

Enforcement is still low-touch through 2026. CalHHS has emphasized capacity building over penalties. "Low-touch" is not "no-touch," though, and signatory status now surfaces in CDPH survey conversations and managed-care contracting reviews. Catching up costs you about an hour and an email to your EHR vendor. The cost of staying non-compliant is real now.

The connection to every other California AI rule

The DxF earns its place next to the AI rules because data fluidity is the precondition for every other operational benefit you can squeeze out of AI. The building that signs the DSA and connects to a QHIO can populate MDS sections from inbound hospital discharge summaries automatically. It can give its AI tools the clinical context they need to surface meaningful patterns. It can defend itself in a survey with a complete care-transitions record. The building that does not sign stays stuck with whatever its EHR vendor lets it see.
