​3.5 Provider Application Process

Participating hospitals, hospital-sponsored practices, treatment centers, community-based groups, and individual providers should call 1-888-801-1660 to notify Healthfirst about new providers joining an existing practice or to inquire about how to become a participating provider. If the provider is determined to be a desirable candidate he or she will then be required to complete an application package and submit the appropriate credentialing information and required documentation based on their level of participation (e.g., Level III).
