California’s centralized platform for provider directory data
Symphony’s advanced, cloud-based platform serves as a single source of accurate provider information, helping health plans and providers streamline complex data exchange processes.
As California’s statewide data source, Symphony improves the efficiency, quality, and ease of provider directory data. This ensures compliance with regulatory requirements while helping consumers get the information they need.
Orchestrating an industry-wide movement
We help health plans and providers across the state maintain the hundreds of data points they have on every provider. We also work with the industry’s top leaders to influence critical provider data requirements — like when we provided testimony to the U.S. Senate on the importance of accurate provider data. To date, Symphony:

Improving directory provider data
Plans can access all provider information in one place to easily update their member directories, create efficiency, and drive industry data standardization.
Streamlining provider data validation
Providers can update and validate information to all Symphony health plans simultaneously, reducing administrative burden and ensuring contracted plans always have up-to-date information.
Why join Symphony?
Online provider directories play an important role in helping consumers make decisions about their care and insurance coverage. Yet these directories are often incomplete, inaccurate, and difficult to maintain. We partner with health plans and providers to streamline the burdensome work associated with provider data exchange and validation.
Compliance, simplified
We simplify complex data exchange processes between providers and health plans to support compliance with regulatory mandates, including SB-137, HR-133, and more.
High-quality provider directory data
Symphony validates data from numerous primary and secondary sources, including provider-sourced data, to ensure plan directories contain the most accurate provider information.
Led by industry experts
We’re supported by the California Department of Managed Health Care (DMHC) and led by IHA’s 40-member Board of Directors with leaders from the state’s top health plans, providers, health systems, purchasers, and universities. By working together, we create solutions that work for everyone while influencing the future of provider directory data in California.
Partnering for success
Availity, the nation’s largest real-time health information network, is the single-source technology partner for Symphony. Availity Provider Data Management (PDM), a web-based multi-payer platform designed for provider information, supports Symphony’s data sharing, reconciliation, and validation for participating health plans and providers.
The synergy between Availity and Symphony lies in empowering health plans and providers to exchange information more efficiently and work within standardized business rules and workflows. With these ongoing improvements, IHA is progressing toward a future where high-value, equitable care is the new standard.”
