How To Submit Claims To Blue Cross and Blue Shield of North Carolina

For Blue Cross and Blue Shield of North Carolina, the practical claims workflow usually starts with electronic submission guidance and only falls back to paper instructions when the payer documents a mailing address for specific claim types or exceptions. The details below keep the workflow broad instead of reducing it to a single address.

At a glance

• Commercial claims can be submitted through Blue e digital forms, EDI as a trading partner or through a clearinghouse, or by mail to PO Box 35 in Durham.
