Official Description

Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; with brushing or protected brushings

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A bronchoscopy is a medical procedure that involves the examination of the airways and lungs using a bronchoscope, which can be either rigid or flexible. This procedure may be performed with or without the assistance of fluoroscopic guidance, which utilizes real-time imaging to enhance visualization during the examination. The bronchoscope is inserted through the patient's nose or mouth and is carefully advanced into the oropharynx, allowing for a thorough examination of the vocal cords and trachea. The bronchoscope is then further advanced into the right and left mainstem bronchi, where any abnormalities can be identified and documented. In cases where a rigid bronchoscope is utilized, a telescope or flexible bronchoscope may be introduced through the rigid device to facilitate visualization of the distal segments of each mainstem bronchus. The procedure may also include the collection of cell samples through brushing or protected brushings, which are critical for cytological analysis. These samples are subsequently sent to a laboratory for examination, aiding in the diagnosis of various pulmonary conditions. The bronchoscope is then carefully withdrawn after the procedure is completed.

1. Indications

The bronchoscopy procedure, specifically CPT® Code 31623, is indicated for various clinical scenarios where direct visualization of the airways is necessary. The following conditions may warrant the performance of this procedure:

  • Suspicion of Lung Pathology - When there is a need to investigate potential abnormalities within the lungs, such as tumors, infections, or other pathological conditions.
  • Persistent Cough or Hemoptysis - In cases where patients present with a chronic cough or coughing up blood, bronchoscopy can help identify the underlying cause.
  • Abnormal Imaging Results - If imaging studies, such as chest X-rays or CT scans, reveal suspicious lesions or other abnormalities, bronchoscopy may be performed for further evaluation.
  • Need for Tissue Sampling - When there is a requirement to obtain tissue samples for histological examination, bronchoscopy allows for the collection of samples through brushing or protected brushings.

2. Procedure

The bronchoscopy procedure involves several key steps that ensure a thorough examination of the airways. The following outlines the procedural steps associated with CPT® Code 31623:

  • Step 1: Preparation - The patient is positioned appropriately, and sedation may be administered to ensure comfort during the procedure. The area around the nose and mouth may be anesthetized to minimize discomfort.
  • Step 2: Insertion of the Bronchoscope - The bronchoscope, which can be either rigid or flexible, is inserted through the patient's nose or mouth. The physician carefully advances the bronchoscope into the oropharynx, ensuring that the airway is clear for visualization.
  • Step 3: Examination of the Airways - Once the bronchoscope is in place, the physician examines the oropharynx, vocal cords, and trachea. The bronchoscope is then advanced into the right and left mainstem bronchi, allowing for a comprehensive assessment of the bronchial tree.
  • Step 4: Collection of Cell Samples - If indicated, a cytology brush is advanced through the bronchoscope to perform cell brushing. This technique is utilized to collect cell samples from the bronchial walls, which are essential for cytological analysis.
  • Step 5: Withdrawal of the Bronchoscope - After the examination and any necessary sampling are completed, the bronchoscope is carefully withdrawn from the airway, and the patient is monitored for any immediate post-procedure complications.

3. Post-Procedure

Following the bronchoscopy procedure, patients are typically monitored for a short period to ensure there are no immediate complications, such as bleeding or respiratory distress. It is common for patients to experience a sore throat or mild discomfort following the procedure, which usually resolves quickly. The physician may provide specific post-procedure instructions, including recommendations for hydration and activity restrictions. Additionally, patients may be informed about when to expect results from any tissue samples sent for laboratory analysis. Follow-up appointments may be scheduled to discuss findings and any further necessary interventions.

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.
GC This service has been performed in part by a resident under the direction of a teaching physician
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
RT Right side (used to identify procedures performed on the right side of the body)
LT Left side (used to identify procedures performed on the left side of the body)
CR Catastrophe/disaster related
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).
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.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
