In need of help on facility coding... Physician performed a bilateral inferior turbinate outfracture with Goldman elevator that included a submucous turbinate tissue ablation. Then performed a blunt reduction of the nasal septum with Goldman elevator. Since the nasal septum was not an open procedure is it inappropriate to code 30520 with 30140-50? Should the surgery center bill an unlisted procedure instead (30140-50, 30999).

ENT is my weakest specialty, so any insight is appreciated.
