  • What is credentialing?

    Credentialing is the process of reviewing, verifying and periodically re-verifying practitioner and/or organization credentials in accordance with defined criteria.

  • What does the credentialing process include?
    Prior to contract execution, we ensure providers and organizations meet credentialing criteria and are approved by the Regional Network and Credentialing Committee (RNCC). Once the contract is agreed upon, the credentialing process will begin and includes these steps:
  1. Application. If you are not yet accredited for participation in our plan, complete and submit the Practitioner Facility Credentialing and Recredentialing Application.
  2. Application review. We confirm you have fully completed the application and supplied all required supporting documents.
  3. Credentials verification. We verify information, including but not limited to license status, insurance coverage, and education/training, using criteria defined to meet accreditation, regulatory, and other applicable requirements.
  4. Committee review. If credentials meet minimum standards, the application is sent to a Regional Network and Credentialing Committee (RNCC) comprised of Magellan Complete Care of Arizona clinical staff and professional peers. The RNCC reviews applications subject to business needs and in accordance with applicable state law.
  • How long does the credentialing process take?
    Magellan Complete Care of Arizona (HMO SNP) will complete the process in a manner that is, at a minimum, within required federal and/or statement guidelines. Once all required documents have been submitted, MCC of AZ (HMO SNP) has up to 90 days to complete the credentialing process. Once the credentialing process is completed, MCC of AZ (HMO SNP) will execute the contract. A copy will be sent to the group/organization and the contract will be entered into our claims and provider demographic systems.
