Official Description

Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; with transbronchial needle aspiration biopsy(s), trachea, main stem and/or lobar bronchus(i)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A bronchoscopy, whether performed using a rigid or flexible instrument, is a medical procedure that allows for direct visualization of the airways, including the trachea and bronchi. This procedure can be conducted with or without the assistance of fluoroscopic guidance, which utilizes real-time imaging to enhance the accuracy of the examination. During the bronchoscopy, the physician inserts the bronchoscope through the patient's nose or mouth, advancing it into the oropharynx for an initial examination. The vocal cords are also visualized to assess their condition. Following this, the bronchoscope is further advanced into the trachea, where the airway is inspected for any abnormalities. If a rigid bronchoscope is utilized, it may be accompanied by a telescope or a flexible bronchoscope that is inserted through it, allowing for a more detailed view of the distal segments of the mainstem bronchi. A critical component of this procedure is the transbronchial needle aspiration (TBNA) biopsy, which involves the introduction of a catheter with a flexible needle tip. This needle is carefully navigated through the trachea or bronchus to the targeted biopsy site. By applying suction and moving the needle back and forth across the tissue or lesion, the physician can collect cellular samples for diagnostic purposes. The procedure is essential for obtaining tissue samples from areas that may be difficult to access, aiding in the diagnosis of various pulmonary conditions.

1. Indications

The bronchoscopy procedure with transbronchial needle aspiration biopsy is indicated for various clinical scenarios where direct visualization and tissue sampling of the airways are necessary. The following conditions may warrant this procedure:

  • Suspicion of Lung Cancer - When there is a need to obtain tissue samples from suspected malignancies in the trachea, main stem bronchus, or lobar bronchus.
  • Diagnosis of Infectious Diseases - To identify infections such as tuberculosis or fungal infections that may affect the airways.
  • Evaluation of Inflammatory Conditions - In cases of unexplained pulmonary symptoms or conditions such as sarcoidosis, where tissue diagnosis is required.
  • Assessment of Airway Obstruction - To investigate the cause of obstructions in the airways, which may include tumors, foreign bodies, or strictures.

2. Procedure

The bronchoscopy procedure with transbronchial needle aspiration biopsy involves several key steps that ensure thorough examination and sampling of the airways. The following outlines the procedural steps:

  • Step 1: Preparation and Anesthesia - The patient is positioned appropriately, and local anesthesia is administered to minimize discomfort during the procedure. Sedation may also be provided to help the patient relax.
  • Step 2: Insertion of the Bronchoscope - A rigid or flexible bronchoscope is inserted through the patient's nose or mouth and advanced into the oropharynx. The oropharynx is examined, and the vocal cords are visualized to assess their condition.
  • Step 3: Advancement into the Trachea and Bronchi - The bronchoscope is carefully advanced into the trachea, where the airway is inspected for abnormalities. The scope is then maneuvered into each mainstem bronchus for further examination.
  • Step 4: Transbronchial Needle Aspiration - A catheter with a flexible needle tip is introduced through the bronchoscope. The needle is directed to the biopsy site within the trachea, main stem bronchus, or lobar bronchus. Suction is applied while the needle is agitated back and forth across the tissue or lesion to collect cellular samples.
  • Step 5: Withdrawal and Recovery - After the biopsy is completed, the catheter and bronchoscope are withdrawn. The patient is monitored during the recovery phase to ensure stability and address any immediate post-procedure concerns.

3. Post-Procedure

Following the bronchoscopy with transbronchial needle aspiration biopsy, patients are typically monitored for any complications such as bleeding, infection, or respiratory distress. It is common for patients to experience mild throat discomfort or cough due to the procedure. Recovery time may vary, but most patients can resume normal activities within a short period, depending on their overall health and the extent of the procedure. Follow-up appointments may be scheduled to discuss biopsy results and any further management required based on the findings.

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).
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
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).
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
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.
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.
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).
