Official Description

Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; with balloon occlusion, when performed, assessment of air leak, airway sizing, and insertion of bronchial valve(s), initial lobe

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Bronchoscopy, as described by CPT® Code 31647, is a medical procedure that involves the examination of the airways using a bronchoscope, which can be either rigid or flexible. This procedure is particularly significant for assessing the airways for size and identifying any air leaks. The bronchoscope is inserted through the mouth and navigated through the oropharynx and trachea, ultimately reaching the right or left mainstem bronchus. Fluoroscopic guidance may be utilized during this process to enhance visualization and accuracy. The procedure includes the use of balloon occlusion to assess air leaks and airway sizing, which is performed with a calibrated balloon catheter. This allows for the identification of airways that are contributing to the air leakage. Once the air leak is located, a bronchial valve can be inserted to manage the leak effectively. The procedure is comprehensive, involving careful evaluation of the bronchial structures and ensuring that any potential injuries are assessed before concluding the examination. The specific code 31647 is reported for the placement of the bronchial valve in the initial lobe, highlighting the procedural focus on addressing air leaks within the bronchial system.

1. Indications

The procedure described by CPT® Code 31647 is indicated for the following conditions:

  • Assessment of Air Leak This procedure is performed to evaluate the presence and extent of air leaks within the bronchial system, which can occur due to various pulmonary conditions.
  • Airway Sizing It is utilized to determine the appropriate size of the airways, which is crucial for subsequent interventions, including the placement of bronchial valves.
  • Insertion of Bronchial Valve(s) The procedure is indicated when there is a need to insert bronchial valves to manage air leaks effectively, particularly in the initial lobe of the lung.

2. Procedure

The procedure involves several critical steps, each designed to ensure thorough evaluation and intervention:

  • Step 1: Insertion of the Bronchoscope The bronchoscope, either rigid or flexible, is inserted through the patient's mouth and advanced into the oropharynx. The clinician carefully navigates the bronchoscope through the trachea and into the right or left mainstem bronchus, utilizing fluoroscopic guidance as necessary to enhance visualization.
  • Step 2: Advancement into Segmental or Subsegmental Bronchus Once in the mainstem bronchus, the bronchoscope is further advanced into the segmental or subsegmental bronchus of the lobe that is suspected to contain the air leak. This step allows for direct visualization of the bronchial structures.
  • Step 3: Airway Sizing A calibrated balloon catheter is used to perform airway sizing. This involves measuring the diameter of the airways to ensure that the appropriate size of bronchial valve can be selected for insertion.
  • Step 4: Identification of Air Leak Intermittent balloon occlusion is employed to identify the airways leading to the air leakage. The balloon catheter is advanced and inflated while monitoring the air leak in the water seal chamber, allowing the clinician to observe any reduction or cessation of air leakage.
  • Step 5: Insertion of Bronchial Valve Once the air leak is confirmed and assessed, a delivery catheter is advanced through the bronchoscope to place the bronchial valve. This step is crucial for managing the air leak effectively.
  • Step 6: Final Examination After the valve placement, the bronchoscope is passed again into the segmental or subsegmental bronchus to examine for any evidence of injury. This thorough evaluation ensures that the bronchial structures are intact and functioning properly.
  • Step 7: Withdrawal and Final Inspection Finally, the bronchoscope is withdrawn, and a comprehensive examination of the bronchi, trachea, and oropharynx is conducted to ensure there are no complications or additional issues that need to be addressed.

3. Post-Procedure

Post-procedure care following the bronchoscopy with balloon occlusion includes monitoring the patient for any immediate complications, such as respiratory distress or bleeding. Patients may be observed for signs of air leaks or other adverse effects related to the procedure. Recovery time can vary based on the individual patient's condition and the complexity of the procedure performed. It is essential to provide appropriate follow-up care and instructions regarding any activity restrictions or signs of complications that the patient should be aware of after the procedure.

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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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.)
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
