CPT® Code 30140

The CPT® Code 30140 refers to the procedure known as submucous resection of the inferior turbinate, which can be performed either partially or completely using any method. This surgical intervention is primarily aimed at alleviating nasal obstruction that arises due to the enlargement of the soft tissue or bone within the inferior turbinate. The inferior turbinate is one of three sets of turbinates, or conchae, located on each side of the nasal vestibule, specifically identified as inferior, middle, or superior based on their anatomical position. These turbinates consist of bony structures covered by a layer of spongy mucosa, which plays a crucial role in humidifying and filtering the air we breathe. The inferior turbinate is situated on the lower lateral wall of the nasal cavity, making it accessible through the nostril for surgical procedures. During the submucous resection, the physician first removes the outer layer of the turbinate mucosa, followed by the excision of part or all of the underlying turbinate bone. After this removal, the inner portion of the mucosa is folded over the surgical site and secured with sutures, promoting healing and minimizing complications. This procedure is essential for patients suffering from chronic nasal obstruction, enhancing their quality of life by improving airflow through the nasal passages.
