CPT® Code 31505

The procedure described by CPT® Code 31505 refers to an indirect diagnostic laryngoscopy, which is classified as a separate procedure. This examination is performed by a physician to visualize the larynx, vocal cords, and surrounding structures in the throat. During the procedure, the patient is typically seated comfortably in a chair and is instructed to protrude their tongue. The physician then uses a small round mirror, positioned at the back of the throat, to reflect light into the oral cavity, allowing for a clear view of the laryngeal area. Additionally, the physician may utilize a head mirror to enhance illumination, ensuring optimal visibility of the anatomical structures being examined. In some cases, a rigid endoscope may be employed as an alternative to the mirror technique, providing a more direct visualization of the larynx. The examination focuses on identifying any signs of disease, injury, or abnormalities affecting the vocal cords, tongue, and the upper part of the throat. To facilitate better visualization of the vocal cords during the procedure, the patient may be asked to produce a high-pitched 'eee' sound. This action helps to open up the vocal cords, making it easier for the physician to assess their condition. It is important to note that this code is specifically for diagnostic purposes and does not include any therapeutic interventions, which are covered under different codes such as 31510 for biopsy, 31511 for foreign body removal, and 31512 for lesion removal.
