Quick-reference sheet for Blue Cross Blue Shield regional plans — EDI payer prefixes, alpha prefixes, and the phone lines for providers vs. members. Built for eligibility checks, claims status calls, and figuring out which BCBS entity you're actually dealing with before you dial.
Compiled from commonly circulated billing/RCM reference sheets. Payer numbers, prefixes, and phone lines change without notice — always confirm against the payer portal or the number on the patient's card before relying on this for a live claim.
