Hello all,

This one is new to me.....
Patient had 31255, 31267 and 30930 at the end of the op note reads

"the oroantral fistula was in the left molar region and the lining of the oroantral fistual was debrided, and there was some dead bone in this area which was also debrided then closed."

Doctors calls procedure "coring/and closure of left oroantral fistula"


Any help on CPT would be great! THANKS
