CPT® Code 31520

The CPT® Code 31520 refers to a diagnostic laryngoscopy performed on a newborn, utilizing a direct laryngoscope. This procedure allows the physician to visualize the laryngeal structures directly through the use of fiberoptic technology. There are two primary types of direct laryngoscopes: the rigid angled scope and the flexible scope. The flexible scope is typically inserted through the nostril, while the rigid scope is inserted through the mouth. During the procedure, the physician examines various anatomical areas, including the nasopharynx, oral cavity, oropharynx, hypopharynx, and larynx, for any signs of abnormalities or injuries. These may include lacerations, lesions, strictures, or other pathological conditions. Additionally, the laryngoscope may be advanced into the trachea for further examination. It is important to note that CPT® Code 31520 is specifically designated for diagnostic laryngoscopy in newborns, while different codes apply for patients outside this age group, such as CPT® Code 31525 for non-newborn patients and CPT® Code 31526 when an operating microscope or telescope is utilized to enhance visualization during the procedure.
