Here are some resources for locating an appropriate practitioner or provider when making a referral or authorization request.

e-referral Provider Search feature — Within the e-referral tool, you can search by provider name or national provider identifier. When you have a member selected and then go to select a provider, the system will indicate if the provider is "in" or "out" of network for that member. For more information, see:

Online provider search — bcbsm.com has an online provider search that allows you to look for affiliated providers by first selecting the member's Blue Cross or BCN product and then viewing the network choices by type of care and location. More detailed searches are possible by clicking on More Search Options. Once you have located the provider, you need to log in to e-referral to submit the referral request using the provider's name or NPI.

Referrals to the University of Michigan Health System and Henry Ford Health System — Referrals to these two health systems require using specialty group NPIs rather than referring to an individual practitioner.

Referrals to a hospital — When issuing a referral or outpatient authorization for a hospital, referring providers should enter the facility NPI in the e-referral Servicing Facility ID field.
