Official Description

Laryngoscopy, direct, operative, with operating microscope or telescope, with submucosal removal of non-neoplastic lesion(s) of vocal cord; reconstruction with local tissue flap(s)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 31545 involves a direct laryngoscopy, which is a surgical technique that allows a physician to visualize the larynx and vocal cords directly using specialized instruments. This procedure is performed with the aid of an operating microscope or telescope, enhancing the surgeon's ability to see and operate on the vocal cords with precision. The primary focus of this procedure is the submucosal removal of non-neoplastic lesions located on the vocal cords. Non-neoplastic lesions refer to abnormal growths that are not cancerous, which can affect vocal cord function and overall voice quality. During the procedure, the surgeon utilizes a rigid or flexible laryngoscope, typically inserted through the mouth under general anesthesia, to examine the oral cavity, oropharynx, hypopharynx, and trachea. Once the lesion is identified, instruments such as micro-knives or micro-scissors are employed to carefully incise the vocal cord tissue. The surgeon then uses both blunt and sharp dissection techniques to separate the lesion from the surrounding healthy tissue. After the lesion is excised, the surgical defect is reconstructed using local tissue flaps. This involves developing, trimming, and advancing or rotating a flap of local tissue over the defect, which is then secured in place with sutures. This meticulous approach aims to restore the integrity of the vocal cords while minimizing complications and promoting optimal healing.

1. Indications

The procedure described by CPT® Code 31545 is indicated for the removal of non-neoplastic lesions of the vocal cords. These lesions may present with various symptoms that necessitate surgical intervention, including:

  • Vocal Cord Lesions Non-cancerous growths on the vocal cords that may cause hoarseness, voice changes, or difficulty in phonation.
  • Persistent Hoarseness A prolonged change in voice quality that does not resolve with conservative treatment, indicating the need for further evaluation and potential surgical intervention.
  • Vocal Cord Dysfunction Conditions where the vocal cords do not function properly, leading to breathing difficulties or impaired voice production.

2. Procedure

The procedure for CPT® Code 31545 involves several critical steps to ensure the effective removal of the lesion and reconstruction of the vocal cord. The steps are as follows:

  • Step 1: Anesthesia Administration The patient is placed under general anesthesia to ensure comfort and immobility during the procedure. This is essential for allowing the surgeon to perform the operation safely and effectively.
  • Step 2: Insertion of the Laryngoscope A direct laryngoscope, either rigid or flexible, is inserted through the mouth to provide direct visualization of the larynx and vocal cords. The choice of scope depends on the specific requirements of the surgery and the anatomy of the patient.
  • Step 3: Visualization of the Lesion The operating microscope or telescope is utilized to closely examine the lesion on the vocal cord. This enhanced visualization allows the surgeon to assess the extent of the lesion and plan the surgical approach accordingly.
  • Step 4: Incision and Dissection Using micro-knives and/or micro-scissors, the surgeon carefully incises the vocal cord tissue surrounding the lesion. Blunt and sharp dissection techniques are employed to separate the lesion from the surrounding healthy tissue, ensuring minimal damage to adjacent structures.
  • Step 5: Lesion Removal The non-neoplastic lesion is excised from the vocal cord. The surgeon takes care to remove the lesion completely while preserving as much healthy tissue as possible to maintain vocal cord function.
  • Step 6: Reconstruction with Local Tissue Flap After the lesion is removed, the surgical defect is reconstructed using local tissue flaps. The surgeon develops a flap of local tissue, which is then trimmed and advanced or rotated over the defect. This flap is secured in place with sutures to promote healing and restore the integrity of the vocal cord.

3. Post-Procedure

Post-procedure care following CPT® Code 31545 involves monitoring the patient for any immediate complications related to the surgery. Patients may experience some swelling and discomfort in the throat, which is typically managed with pain relief medications. Voice rest is often recommended for a specified period to allow the vocal cords to heal properly. Follow-up appointments are essential to assess the healing process and ensure that the vocal cords are functioning correctly. The surgeon may provide specific instructions regarding activity restrictions and signs of complications that should prompt immediate medical attention.

50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
GC This service has been performed in part by a resident under the direction of a teaching physician
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
