Need help as I haven't had one of these in a long time. OB pt presents for exam and NST outside of the global package because she was in a car accident the day before (rear ended). NST was fine. How do the use the dx codes? We normally follow her as an OB pt with history of infert V23.0. Should I code V23.0,the E code and then the V22.2? I'm needing to show this visit is outside of the routine global visits and there will be an e/m charge and also the NST. I'm confused because the Ecode and the V22.2 should not be a primary code, correct? Thanks in advance!
