Patient had FESS. During post op doctor billed 31237-50-79, insurance is denying modifier 79 as invalid/not appropriate modifier with procedure code. I have read articles that say modifier 79 is appropriate with 31237 during post op but I have also read that it is not appropriate. When billing post op debridement's do you use modifier 79???
Thank you in advance for your help.
