Official Description

Laryngoscopy, indirect; with removal of foreign body

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 31511 involves an indirect laryngoscopy with the specific purpose of removing a foreign body from the throat. During this procedure, the physician conducts a diagnostic examination of the 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 outward. This positioning allows the physician to gain better access to the throat. To visualize the larynx, the physician uses a small round mirror placed at the back of the throat, along with a light source to illuminate the area. Additionally, the physician may utilize a head mirror that reflects light into the throat, enhancing visibility. In some cases, a rigid endoscope may be employed as an alternative to the mirror technique, providing a more direct view of the laryngeal structures. The examination focuses on the vocal cords, tongue, and the upper part of the throat, where the physician looks for any signs of disease or injury. To facilitate a clearer view of the vocal cords, the patient may be asked to produce a high-pitched 'eee' sound during the examination. This procedure is distinct from other related laryngoscopic procedures, such as those involving biopsy or lesion removal, as it specifically targets the extraction of foreign bodies that may be obstructing the airway or causing discomfort.

1. Indications

The procedure indicated by CPT® Code 31511 is performed in specific clinical situations where a foreign body is suspected to be lodged in the throat or laryngeal area. The following conditions may warrant this procedure:

  • Foreign Body Aspiration The patient may present with symptoms suggesting that a foreign object has been inhaled or swallowed, leading to potential airway obstruction or irritation.
  • Choking Episodes Instances of choking, where the patient has difficulty breathing or swallowing due to an obstructing object, may necessitate this intervention.
  • Persistent Cough or Stridor A persistent cough or stridor (a high-pitched wheezing sound) may indicate the presence of a foreign body in the airway, prompting the need for laryngoscopy.
  • Unexplained Throat Pain Patients experiencing unexplained throat pain or discomfort may require this procedure to identify and remove any foreign objects causing irritation.

2. Procedure

The procedure for CPT® Code 31511 involves several key steps to ensure the safe and effective removal of a foreign body from the larynx. The following outlines the procedural steps:

  • Step 1: Patient Preparation The patient is seated comfortably in a chair, and the physician explains the procedure to alleviate any anxiety. The patient is instructed to extend their tongue to provide better access to the throat.
  • Step 2: Visualization The physician uses a small round mirror positioned at the back of the throat, along with a light source, to visualize the laryngeal area. Alternatively, a rigid endoscope may be utilized for enhanced visualization.
  • Step 3: Examination The physician examines the vocal cords, tongue, and upper throat for any signs of foreign bodies or other abnormalities. The patient may be asked to produce a high-pitched 'eee' sound to improve visualization of the vocal cords.
  • Step 4: Foreign Body Removal Once the foreign body is identified, the physician carefully grasps it using forceps. The foreign body is then extracted from the throat, ensuring minimal trauma to the surrounding tissues.
  • Step 5: Post-Procedure Assessment After the removal, the physician assesses the throat for any residual foreign material or injury and provides appropriate post-procedure care instructions to the patient.

3. Post-Procedure

Following the completion of the procedure, the patient may be monitored for any immediate complications, such as bleeding or difficulty breathing. The physician will provide instructions regarding any necessary follow-up care, which may include observing for signs of infection or further complications. Patients are typically advised to avoid irritants such as smoke or strong odors for a period following the procedure. Additionally, if the foreign body removal was due to aspiration, the patient may be evaluated for any potential respiratory issues that could arise as a result of the incident.

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.
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.)
