5. Are “restricted health care service plans,” as defined by section 1300.49 of the Knox Keene Act (28 C.C.R. § 1300.49), required to sign the Data Exchange Framework (DxF) Data Sharing Agreement (DSA)?

Yes. Health and Safety Code section 130290 does not differentiate between a “restricted health care service plan” and a “full service health care service plan.” Both a “restricted health care service plan” and a “full service health care service plan” are required to sign the DxF DSA.
