The “I’m Just Getting Started” section on the How to Join the DxF page of the Data Exchange Framework website includes a DSA resource list and instructions for signing the DxF DSA.
To support practical and equitable participation across California’s emergency medical services (EMS) system, the Emergency Medical Services Authority (EMSA) intends to offer services as an Intermediary to facilitate Data Exchange Framework (DxF) participation by Local EMS Agencies (LEMSAs) and EMS provider entities. EMSA’s Intermediary services are designed to reduce administrative and technical burden, particularly for smaller or resource-limited agencies, while maintaining compliance with applicable data exchange requirements.
Under this approach, LEMSAs and EMS provider entities may participate in DxF through EMSA’s Intermediary services:
Before using EMSA’s Intermediary services, LEMSAs and EMS provider entities will need to execute an Intermediary Participation Agreement with EMSA. For additional information on EMSA’s intermediary services, please see the EMSA website.
EMSA will provide guidance, technical support, and implementation pathways to support EMS system participation in DxF in a manner that is consistent, scalable, and aligned with EMSA’s and HCAI’s statutory roles.
The Data Exchange Framework (DxF) allows Participants to Exchange Health and Social Services Information through any health information exchange network, health information organization, or technology that meets the requirements of the DSA and its Policies and Procedures. The DxF is not intended to be an information technology system or single repository of data, rather it is a collection of organizations that are required to share health information using national standards and a common set of policies. Some Participants may choose to use services provided by a Nationwide Network or Framework or a Qualified Health Information Organization (QHIO) to meet some or all of the DSA requirements. A QHIO is an Intermediary designated by HCAI that meets DxF requirements for secure data Exchange. Refer to DxF QHIOs At A Glance for more information.
The DxF Data Sharing Agreement and its Policies and Procedures apply when two DxF Participants Exchange HSSI for an Individual, regardless of the Individual’s residency.
Health and Safety Code section 130290(b)(1), requires that required signatories to the DxF Data Sharing Agreement, which includes health insurers and health care service plans, Exchange health information or provide Access to health information to and from every other required signatory. Health and Safety Code section 130290(a)(4) defines “health information” for health insurers and health care service plans as, “at a minimum, the data required to be shared under the federal Centers for Medicare and Medicaid Services Interoperability and Patient Access regulations for public programs as contained in United States Department of Health and Human Services final rule CMS9115-F, 85 FR 25510.” The referenced Centers for Medicare and Medicaid Services final rule requires entities to share adjudicated claims, encounter information, and clinical data contained in USCDI. (42 C.F.R. § 422.119.)
Note, under the DxF, cost information may be excluded from adjudicated claims and encounter information except when providing Individual Access Services. (Data Elements to Be Exchanged Policy and Procedure, Section II.1.iii.)
