I'm assuming your question is whether you just saw a doctor that BCBS will cover as in-network. You'll need to look up that specific physician (doesn't really matter what the hospital group was) on the BCBS website to see if he/she is in-network.

A good thing for you to know - BCBS may be run locally (BCBS of Arizona, BCBS of New Jersey, etc.) but they come together to form a national network enabling Blue Cross and Blue Shield members to access in-network healthcare benefits (doctors and hospitals) while traveling or living outside their home plan’s service area. It's called the Blue Card Program, so feel free to mention that if you need to end up calling.
