Health Care Payments Data Program#


AB 1810 (Chapter 34, Statutes of 2018) included a one-time appropriation for OSHPD to develop and administer a statewide Health Care Payments Database, often referred to as an All Payer Claims Database or APCD. The information from the database 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.

From March 2019 to February 2020 OSHPD convened a Review Committee comprised of health care stakeholders and experts who advised OSHPD on the establishment, implementation, sustainability, and ongoing administration of the database. The Review Committee unanimously approved 36 recommendations that were included in an OSHPD report to the Legislature, released March 9, 2020. See the Review Committee webpage for meeting materials and information on committee members.

Legislative Report#

On March 9, OSHPD submitted the report to the Legislature with recommendations that:

  1. Ensure the database receives appropriate data from identified data submitters.
  2. Provide enforcement mechanisms necessary for these entities to comply.
  3. Protect individual privacy and confidentiality of the data.
  4. Identify a governance structure, including the appropriate entity to operate the database.
