​​​About OPA

The Office of the Patient Advocate (OPA) is moving to the new Center for Data Insights and Innovation (CDII) within the California Health & Human Services Agency. We remain dedicated to improving California health care quality by publicly reporting data for informed decision making. CDII is now responsible for OPA’s previous statutory mandates to publish report cards on health care quality and to analyze complaint data and other information from state health care consumer assistance centers.

OPA’s Main Products

 Quality Report Cards​

OPA displays clinical performance and patient experience data for the state’s largest HMO and PPO health plans on the Health Plan Report Card​. These plans are responsible for providing health care services to more than 15 million commercially insured Californians.

OPA has also introduced cost of care ratings for about 200 of the state’s commercial medical groups, in addition to clinical performance and patient experience data on the Commercial Medical Group Report Card​.

Clinical performance scores for more than 180 Medicare Advantage Medical Groups are also displayed on the Medicare Medical Group Report Card.​​


​ Complaint Data Reports​

OPA’s annual Complaint Data Report provides a meaningful analysis of consumer health care ​complaints​, enabling the identification of systemic problems or disparities and the promotion of effective complaint resolution efforts. The report provides the legislature and other stakeholders with information about the state’s health care consumer assistance centers and consumer complaints reported to the Department of Managed Hea​​​​lth Care, Department of Health Care Services, Department of Insurance, and Covered California. In alignment with our efforts to publicly report accessible data on the quality of California’s health plans, OPA also reports a complaint performance metric that allows consumers to compare health plans’ complaint rates (annual complaints against each health plan per plan member).​​​​
