Welcome to the Health Information Exchange Gateway

The California Department of Public Health (CDPH) shares data with many stakeholders, including providers, hospitals, laboratories, local health jurisdictions and federal agencies. To improve upon our data exchange, analysis, and reporting capabilities, CDPH has developed a secure health information exchange (HIE) web application, the CDPH HIE Gateway. The Gateway will allow providers, hospitals and health information exchange organizations to register and manage public health data exchange with CDPH for specific types of reportable diseases and conditions.

Declaration of Readiness for Meaningful Use Stage 3

Note: In 2018, the Centers for Medicare & Medicaid Services (CMS) has renamed the EHR Incentive Program to the Promoting Interoperability (PI) Program. For historical purposes, the Promoting Interoperability objectives and measures will continue to be referred to as Meaningful Use (MU) objectives and measures in this website. In addition, the registries listed on this website will also meet the CMS Medicare Incentive Payment System (MIPS) Public Health measures.

California Immunization Registry

The California Immunization Registry (CAIR2) is declaring its readiness to meet the Stage 3 Meaningful Use Immunization Measure. CAIR2 will be able to meet the 2015 Edition CEHRT criteria, including:

  • The ability to respond to bidirectional queries (QBP/RSP)
  • The capacity to receive NDC codes

CAIR2 Submitters seeking to meet the Stage 3 Meaningful Use Immunization Measure will be required to complete the online CAIR2 Bidirectional Interest/Readiness Survey. Visit California Immunization Registry for the survey. Interested sites should continue to submit immunization messages to CAIR2.

CalREDIE Electronic Lab Reporting (ELR)

CalREDIE previously declared readiness to meet the Stage 3 Meaningful Use Electronic Lab Reporting (ELR) Measure. CalREDIE meets the 2015 Edition CEHRT criteria. As noted in the CDC document, there are no changes for ELR between 2014 and 2015 Edition CEHRT.

CalREDIE Electronic Case Reporting (eCR)

Visit the California Reportable Disease Information Exchange (CalREDIE) eCR Registration Portal for Electronic Case Reporting (eCR) with the California Department of Public Health.

As of July 1, 2017, CalREDIE declared readiness to meet the CMS Promoting Interoperability Program (PIP) requirements for electronic case reporting (eCR) at the California Department of Public Health (CDPH). For questions regarding PIP requirements for CDPH please email:

To register for CDPH CalREDIE eCR, visit the California Reportable Disease Information Exchange (CalREDIE) eCR Registration Portal. Healthcare providers within Los Angeles, San Diego, and Solano counties please check in with your local health department for instructions on how to register and submit eICRs for your jurisdiction.

For submitters who have already registered for eCR and/or have been submitting data prior to November 1, 2021, no further action is needed.

Syndromic Surveillance

CDPH does not participate in Syndromic Surveillance. Please check with your local health department to see they are able to accept syndromic surveillance data. If they cannot, you can use screenshots from that web page and this web page as proof of exemption from the syndromic surveillance requirement.

California Cancer Case Registry

The California Cancer Registry is declaring its readiness to meet the Stage 3 Meaningful Use Cancer Measure. CCR will be able to meet the 2015 Edition CEHRT criteria, including incorporation of the updated Cancer Implementation Guide HL7 CDA ® Release 2 Implementation Guide: Reporting to Public Health Cancer Registries from Ambulatory Healthcare Providers, Release 1, DSTU Release 1.1 – US Realm

California Parkinson's Disease Registry

California Health and Safety Code (HSC) 103860-103870 requires healthcare providers diagnosing or providing treatment to Parkinson’s disease patients to report each case of Parkinson’s disease to CDPH. Per recent legislation with CA SB97, beginning July 1, 2018, a hospital, facility, physician and surgeon, or other health care provider diagnosing or providing treatment to Parkinson’s disease patients must report each case of Parkinson’s disease to the department, as prescribed. The California Parkinson’s Disease Registry (CPDR) will be a statewide population based registry that will be used to measure the incidence and prevalence of Parkinson’s disease.

Surprisingly, little is known about how Parkinson's Disease is distributed among different population groups and whether the patterns of disease are changing over time. California's large and diverse population makes it ideal for providing important information about this disease. CPDR will greatly expand our understanding of Parkinson's disease and ultimately improve the lives of those affected.

Before beginning the Gateway registration process, make sure to:

  1. Check the California Public Health Electronic Reporting Capacity Matrix to see whether your Local Health Jurisdiction prefers you to use the CDPH HIE Gateway or a local solution for Public Health Reporting.

  2. Set aside 15-20 minutes to complete the process - data will not be saved unless registration is completed.

  3. Have all your Organization/Site and EHR vendor/IT technical support contact information available (contact names, email addresses, phone #s). With respect to MU, it is not necessary for individual EPs to register at the Gateway as CDPH will acknowledge MU-qualifying public health reporting per Site.

  4. Define how your Site will submit data to the Gateway (choose 1 of these 3 options):

    1. Directly to the Gateway from your EHR system
    2. Through an intermediary facility (e.g. HIE/HIO, vendor data warehouse, health plan data warehouse, etc.)
    3. Will operate as an HIE/Sending Facility and submit data on behalf of other Sites

When you have assembled all this necessary information and are ready to begin Gateway registration, click below on the type of public health data you wish to submit and proceed with registration. Once you have registered to submit one public health data type (e.g. immunizations), registration for submission of other data types will take less time.
