Official Description

Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; diagnostic, with cell washing, when performed (separate procedure)

© 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 include fluoroscopic guidance, which utilizes real-time imaging to assist in navigating the bronchoscope through the respiratory tract. The primary purpose of a bronchoscopy is to diagnose conditions affecting the airways, such as tumors, infections, or other abnormalities. During the procedure, the bronchoscope is inserted through the nose or mouth and advanced into the oropharynx, allowing for a thorough examination of the vocal cords, trachea, and mainstem bronchi. If abnormalities are detected, further diagnostic techniques may be employed, such as cell washing or brushing, to collect samples for laboratory analysis. Cell washing involves the injection of sterile saline solution into the lung, which is then aspirated to retrieve cellular samples. These samples are crucial for cytological examination to identify any pathological conditions. The bronchoscope is carefully withdrawn after the examination and any necessary procedures are completed, ensuring that the patient is monitored throughout the process for safety and effectiveness.

1. Indications

The bronchoscopy procedure is indicated for various diagnostic purposes, particularly when there is a need to investigate abnormalities within the airways or lungs. The following conditions may warrant the performance of a bronchoscopy:

  • Suspicion of Lung Disease - When there are clinical signs or symptoms suggesting the presence of lung disease, such as persistent cough, hemoptysis (coughing up blood), or unexplained respiratory distress.
  • Abnormal Imaging Results - If imaging studies, such as chest X-rays or CT scans, reveal suspicious masses, lesions, or other abnormalities in the lungs that require further evaluation.
  • Need for Tissue Sampling - When there is a requirement to obtain tissue samples for histological examination to diagnose conditions like lung cancer, infections, or inflammatory diseases.
  • Assessment of Airway Obstruction - In cases where there is a need to evaluate and potentially relieve airway obstructions caused by tumors, foreign bodies, or other factors.

2. Procedure

The bronchoscopy procedure involves several key steps to ensure a thorough examination of the airways and lungs. The following outlines the procedural steps:

  • Step 1: Preparation - The patient is positioned comfortably, and local anesthesia may be administered to minimize discomfort during the procedure. Sedation may also be provided to help the patient relax.
  • 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 Airway - Once the bronchoscope is in place, the physician examines the oropharynx, vocal cords, trachea, and mainstem bronchi. Any abnormalities, such as lesions or inflammation, are noted for further evaluation.
  • Step 4: Cell Washing (if performed) - If cell washing is indicated, sterile saline solution is injected into the lung through the bronchoscope. The saline is then aspirated to collect cellular samples for laboratory analysis.
  • Step 5: Additional Sampling Techniques (if performed) - If necessary, a cytology brush may be advanced through the bronchoscope to perform cell brushing, allowing for the collection of additional samples for cytological examination.
  • Step 6: Withdrawal of the Bronchoscope - After the examination and any sampling procedures are completed, the bronchoscope is carefully withdrawn from the airway, and the patient is monitored for any immediate post-procedure effects.

3. Post-Procedure

After 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 care instructions, including recommendations for hydration and activity restrictions. Additionally, patients may be informed about when to expect results from any samples collected during the procedure, as these will be sent to a laboratory for analysis. Follow-up appointments may be scheduled to discuss findings and any further necessary interventions based on the results.

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
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).
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
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.
XP Separate practitioner, a service that is distinct because it was performed by a different practitioner
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
XE Separate encounter, a service that is distinct because it occurred during a separate encounter
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.
AG Primary physician
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.)
FS Split (or shared) evaluation and management visit
CR Catastrophe/disaster related
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.
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).
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).
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.
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.)
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).
