I am confused on when to use these codes. My physician performed a septo and coblation of inferior turbinates. this is what is described in the op note. I billed 30520 and 30802. my problem is that the hospital is is wanting to use 30140 for the turbinates but the op noted does not say anything about resection. what is the difference between these two codes? am i to use 30140 when a septo is done?
