How To Apply

Medical Network Application Process

The credentialing process includes three keys steps.

  • First, register with CAQH and log into CAQH ProView®.
  • Second, document the CAQH Identification number you receive once registered.
  • Third, complete the CareFirst Questionnaire.

Your application cannot be reviewed until all three steps are completed. The information below includes everything you need to know to complete this process.


Step 1: Register with CAQH

  • To start the credentialing process, you must register with CAQH. When you use CAQH ProView, you eliminate the need to complete multiple, lengthy paper forms and reduce administrative burden.
  • For more information about how to use CAQH ProView, please view the CAQH Provider Quick Reference Guide as well as the 'CAQH ProView Help' section, and review their FAQs.

Step 2: Document your CAQH Identification Number

  • Once you are registered with CAQH, you will be assigned a CAQH Identification Number. You will need to have your assigned CAQH Identification Number to complete Step 3.

Step 3: Complete the CareFirst Questionnaire
