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 sure consumers have the right information when choosing a physician or health plan online.

Why join Symphony?

Symphony was created to address industry-wide challenges to provider data management. We partner with health plans to streamline the work associated with outreach, roster updates, data reconciliation, validation, and processing changes. And we partner with providers to streamline the way they share information with plans.


Driven by collaboration

IHA is bringing health plans, provider organizations, regulators, and others across California together to improve the information that consumers access in health plan directories. Collaboration is the key to industry-wide standardization, so we’re working with stakeholders to make sure Symphony works for everyone.

One process does not fit all. No matter how you currently manage provider data, we connect to what works and partner with you to figure out how to streamline what doesn’t. Whether you are a health plan or a large provider organization, our client success team is there to help you as you join Symphony and adjust to new industry-wide standardization. 

Enhanced data quality

Symphony gives health plans and providers the tools to confidently meet state and federal regulatory requirements —improving data quality and driving industry standardization. We also facilitate a transparent data exchange process so plans and providers can hold each other accountable and achieve better results together.
