California’s centralized platform for provider data management

The Symphony Provider Directory is a cloud-based technology platform that serves as a single source for provider directory data, including demographics, services, products, and networks. Symphony is not a consumer-facing directory but, by bringing the industry together to improve the quality of provider data, we ensure that consumers have the right information when choosing a physician or health plan online.

Orchestrating an industry-wide movement

We’re working with health plans and provider organizations across the state, helping them manage the hundreds of data points they have on every provider. To date, Symphony:
