I have a question, we have a patient who has Cigna and BCBS. Cigna paid as primary and then turned around and requested a refund for other insurance primary. We then verified BCBS was primary but according to the birthday rule the patients wife is the subscriber with Cigna and therfore would make Cigna primary. Then we were told by Cigna that since he is the subscriber with BCBS and not a dependent, Cigna would be secondary. Does this supersede the birthday rule???
