This is all done online now, with their onboarding form, which can be found by CLICKING HERE
Go to "How to Join the BCBSNM provider network"

Under Step One is their onboarding form...which you can click on to start the process.  You will need to upload documents to the application, such as your Disclosure form, the provider's license, insurance, etc.  You will need to have those available as PDFs when you complete this.  

Upon submission, you should receive an email confirmation and a case number.  If you do not get a case number, something may not have worked properly.
