Overview

The Health Care Payments Database (HPD) is California’s All Payer Claims Database or APCD. The HPD is a research database comprised of healthcare administrative data: claims and encounters generated by transactions among payers and providers on behalf of insured individuals. The HPD collects claim and encounter data as submitted from California payers.

The information from the HPD System is intended to support greater health care cost transparency and will be used to inform policy decisions regarding the provision of quality health care, and to reduce health care costs and disparities. It is also intended for the information to be used to develop innovative approaches, services, and programs that may have the potential to deliver health care that is both cost effective and responsive to the needs of all Californians.

To maximize its utility and value for California policymakers, researchers, and others interested in improving California’s healthcare system, HCAI intends for the HPD to be as comprehensive and complete as possible by increasing the quality, volume, and variety of data collected over time.

Program Goals

The HPD Program has developed the following goals, based on the legislative intent outlined in the authorizing statute.

  • Provide public benefit for Californians and the state while protecting consumer privacy.
  • Increase transparency about health care costs, utilization, quality, and equity.
  • Inform policy decisions on topics including the provision of quality health care, improving public health, reducing disparities, advancing health coverage, reducing health care costs, and oversight of the health care system and health care companies.
  • Support the development of approaches, services and programs that deliver health care that is cost effective, responsive to the needs of enrollees, and recognizes the diversity of California and impacts of social determinants of health.
  • Improve data transparency to achieve a sustainable health care system and more equitable access to affordable and quality health care for all.
  • Learn about and seek to improve public health, population health, social determinants of health, and the health care system, not about individual patients.

Public Reporting

HCAI is required to produce publicly available information from the database, including data products and analytic reports, to support the goals of the program. The HPD Advisory Committee is responsible for advising HCAI on principles and priorities for public reporting.

HCAI anticipates continuing to advance the accessibility and usefulness of HPD public reports as the database becomes more comprehensive and complete and HCAI builds its capacity over time.

Data Access and Release

HCAI is required to develop a comprehensive data access and release program and convene a Data Release Committee (DRC) to advise HCAI and review requests for access to nonpublic data.

Researchers, state agencies, and other qualified applicants can begin requesting access to non-public data starting later this month. More information to come.

Stakeholder Engagement

HPD Program Advisory Committee

HCAI is required to convene an HPD Program Advisory Committee comprised of health care stakeholders and experts to assist and advise the HCAI Director in formulating program policies regarding data collection, management, use, access, and development of public information to meet the goals of the HPD Program. The committee does not have decision-making authority related to the administration of the database but will serve as a forum for stakeholder and public engagement on policy decisions, while fostering accountability and transparency.

HPD Data Release Committee

HCAI is required to convene a Data Release Committee (DRC) to advise on requests for access to non-public data.

The DRC is an integral part of the HPD Program and will be supporting HCAI to:

  • Lay the foundation for HPD data access and release and contribute to the launch of an effective and credible Data Release Program
  • Advise HCAI on relevant policies and processes
  • Participate in thoughtful deliberation to weigh broad use of HPD data and public benefit to Californians with protection of patient privacy  
  • Review and make recommendations to HCAI on access to and release of non-public HPD data

The DRC is made up of subject matter experts representing key stakeholder groups including: consumers, labor, providers (both at clinician and hospital levels), payers, purchasers, suppliers, and researchers.

HPD Program Data Submitters

The enabling legislation identifies the following entities as mandatory submitters to the HPD:  

  • Health care service plans, including a specialized health care service plan. 
  • Insurers licensed to provide health insurance, as defined in Section 106 of the Insurance Code. 
  • Self-insured plans subject to Section 1349.2, or a state entity, city, county, or other political subdivision of the state, or a public joint labor management trust that offers self-insured or multiemployer-insured plans that pay for or reimburse any part of the cost of health care services. 
  • The State Department of Health Care Services, for those enrolled in Medi-Cal and other insurance affordability programs, whether enrolled in Medi-Cal managed care, fee-for-service Medi-Cal, or any other payment arrangement. 
  • The legislation also specifies additional voluntary submitters, who can opt-in to submit their data to the HPD System.

HPD Program Voluntary Submitters

Many health benefit programs are increasingly concerned about the continued escalation of health care costs and are interested in more effective use of data and transparency to drive the development of solutions. An estimated 4-5 million Californians are covered by ERISA self-funded employers and other purchasers, which are not mandatory submitters under the HPD Program. These purchasers may choose to contribute their data to the HPD. The more comprehensive the HPD is in reflecting the entire population of California, the more accurate the analytic findings will be and the greater the likelihood of achieving both purchaser goals and HPD program goals – including transparency, informed policy decisions, improved health care, and equitable access to affordable and high-quality care.
