I am fairly new to Anesthesia coding and struggle with the use of modifiers at times. I've been a primary coder for years but this trips me up sometimes. I have a patient that had a normal vaginal delivery and then underwent a tubal. The anesthesia providers were different for each service. The tubal was performed right after the delivery. I used 00851-59 as my code on the tubal portion of the procedure. I received a denial that -59 was the incorrect modifier for this procedure. I get payment ok when the -59 is used and the same provider is in on the delivery and then the tubal. Any advice would be awesome!!! Thank you!!!
