Standard Credentialing Application at CAQH
As part of eternalHealth’s Provider Credentialing process, we utilize Council for Affordable Quality Healthcare, Inc. (CAQH), to help streamline the process and reduce any additional burden on our providers.
This is a platform utilized by many physicians and health plans, and is a fast and easy way to securely submit your information at no cost to you.
If you already have a CAQH Profile, all you need to do is make sure you do not have an expired attestation and your information is up to date. We will take care of the rest!
If you do not have a CAQH Profile, please click the link here and follow the prompts to create your profile and complete your application.
What happens next?
- CAQH will notify you once your application is complete.
- If you do not fully complete the application, someone from CAQH will contact you.
