My patient scheduled an E/M vist for multiple issues and during the visit the Dr. says you haven't had your annual, so let's do that also. The Dr wants to bill the E/M 99213-99215 as the primary code because that's WHY the patient came in and use the prevenative 99392-99397-25 as the secondary code. I've never seen it billed this way. We have always have billed the annual first with the E/M with modifier 25. What would be the correct way to bill this?
