Hi, I see a lot of college kids on their parents' insurance plans so they have a different BCBS plan originating in another state then where I practice/am credentialed. I saw a help article saying I need to submit through my local BCBS instead of their state of origin BCBS, but there was no instruction on how to do this. Has anyone does this before and know how? I also have already submitted a claim that was rejected (was submitted to BCBS of TX instead of BCBS of LA where I work), and I'm not sure how to amend this claim and resend out. Help!
