Hello! I have a question on the best way to bill for the PKU and a UA. For the PKU we do the blood draw and prep the sample then send it off to a lab. We use the 36416 for the blood draw. Should we also be billing the 84030 for the PKU as well or just the code for the blood draw? Also i was wondering if any one has any tips or a better way to bill for the UA (81002). We are getting denials on these codes, but not consistantly. More are being denied now than paid. The denial reasons are inconsistant as well. Any ideas? Thanks for any help!
