Official Description

Laryngoscopy, indirect; with removal of lesion

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 31512 refers to an indirect laryngoscopy that includes the removal of a lesion. In this procedure, the physician conducts a thorough examination of the patient's larynx, which is the area of the throat that houses the vocal cords. The patient is typically seated comfortably in a chair and is instructed to extend their tongue. This positioning allows the physician to gain better access to the throat. The physician utilizes a small round mirror, which is strategically placed at the back of the throat, and illuminates the area with a light source. Additionally, the physician may wear a head mirror that aids in reflecting light to enhance visibility during the examination. During the indirect laryngoscopy, the physician inspects the vocal cords, tongue, and the upper part of the throat for any abnormalities, signs of disease, or injuries. To facilitate a clearer view of the vocal cords, the patient may be asked to produce a high-pitched 'eee' sound. This sound helps to open up the vocal cords, making them more visible for examination. The procedure is distinct from other related codes, such as CPT® 31510, which involves a biopsy, and CPT® 31511, which pertains to the removal of a foreign body. In the case of CPT® 31512, the focus is on identifying and completely excising a lesion that has been detected during the laryngoscopic examination.

1. Indications

The procedure indicated by CPT® Code 31512 is performed for various reasons related to the examination and treatment of lesions in the laryngeal area. The following conditions may warrant this procedure:

  • Presence of a Lesion The procedure is indicated when a lesion is identified in the larynx that requires removal.
  • Suspicion of Disease Indirect laryngoscopy with lesion removal may be indicated when there are signs or symptoms suggesting a potential disease affecting the vocal cords or surrounding structures.
  • Injury Assessment The procedure may be performed to assess and remove lesions resulting from trauma or injury to the throat area.

2. Procedure

The procedure for CPT® Code 31512 involves several key steps that ensure a thorough examination and removal of the lesion. The following outlines the procedural steps:

  • Step 1: Patient Preparation The patient is seated comfortably in a chair, ensuring they are relaxed and able to follow instructions. The physician explains the procedure to the patient, addressing any concerns and ensuring informed consent is obtained.
  • Step 2: Tongue Extension The patient is instructed to stick out their tongue, which allows the physician better access to the throat. This positioning is crucial for the subsequent steps of the procedure.
  • Step 3: Use of the Mirror The physician holds down the patient's tongue and positions a small round mirror at the back of the throat. This mirror is essential for visualizing the larynx and surrounding structures.
  • Step 4: Illumination A light source is directed into the mouth, often with the aid of a head mirror worn by the physician. This illumination is vital for enhancing visibility during the examination.
  • Step 5: Vocal Cord Examination The physician examines the vocal cords, tongue, and top of the throat for any signs of disease or injury. The patient may be asked to produce a high-pitched 'eee' sound to facilitate better visualization of the vocal cords.
  • Step 6: Lesion Identification If a lesion is identified during the examination, the physician prepares to remove it. The lesion is carefully assessed to determine the best approach for removal.
  • Step 7: Lesion Removal The physician proceeds to remove the lesion in its entirety, ensuring that the surrounding tissues are preserved as much as possible. This step is critical for both diagnostic and therapeutic purposes.

3. Post-Procedure

After the completion of the procedure, the patient may be monitored for any immediate complications or adverse reactions. Post-procedure care typically includes instructions on how to care for the throat area, potential dietary modifications, and signs of complications to watch for, such as excessive bleeding or difficulty breathing. The physician may schedule a follow-up appointment to assess the site of the lesion removal and discuss any further treatment or pathology results if a biopsy was performed. It is essential for the patient to adhere to the post-procedure guidelines provided by the physician to ensure optimal recovery.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
