I am wondering if anyone can supply any information regarding which diagnosis code/codes should be used when the physician performs a nasal endoscopy in the post op period? There are no indications for the procedure post operatively and the procedure note simply states "bilateral nasal endoscopy reveals a near midline septum without hematoma. No stents, purulence, polyps, or debis. Excellent patency, healting and quiescence". V67.00 would not be adequate to get the procedure paid would it? Should I be using diagnosis codes related to the reason for the surgery? Any information regarding the use of diagnosis codes in this situation would be much appreciated.
