CPT code 30140 denotes a submucous resection of the inferior turbinate, a surgical procedure to reduce turbinate tissue and improve nasal airflow. Nationally, this code is used in otolaryngology practices and surgical settings to bill for partial or complete submucosal turbinate resections performed by any method. It matters clinically and administratively because turbinate surgery is a common intervention for chronic nasal obstruction and allergic or structural causes of nasal airflow limitation.
