Official Description

Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; with transendoscopic endobronchial ultrasound (EBUS) during bronchoscopic diagnostic or therapeutic intervention(s) for peripheral lesion(s) (List separately in addition to code for primary procedure[s])

Common Language Description

The procedure described by CPT® Code 31654 involves the use of a bronchoscope, which can be either rigid or flexible, to examine the airways. This procedure is performed by inserting the bronchoscope through the patient's nose or mouth, allowing access to the oropharynx, trachea, and mainstem bronchi. Fluoroscopic guidance may be utilized during this process to enhance visualization. The primary goal of this procedure is to identify any abnormalities within the airways. In conjunction with the bronchoscopy, a specialized miniaturized ultrasound probe is introduced through a flexible bronchoscope that has a biopsy channel. This ultrasound probe is specifically designed for transendoscopic endobronchial ultrasound (EBUS) and is employed during a primary diagnostic or therapeutic bronchoscopic intervention aimed at peripheral lesions. The ultrasound probe evaluates the airway walls, mediastinum, and lung structures. Once positioned within the airway, the probe's balloon tip is inflated to ensure full contact with the airway wall, allowing for detailed ultrasonic imaging of the wall structures and surrounding mediastinum. The probe is then maneuvered along the airway to provide a comprehensive evaluation of the airway and adjacent anatomical structures.

1. Indications

The procedure described by CPT® Code 31654 is indicated for various clinical scenarios involving peripheral lesions. These indications may include:

  • Peripheral Lesions The procedure is performed to evaluate and diagnose abnormalities located in the peripheral regions of the lungs, which may not be accessible through standard bronchoscopy alone.
  • Suspicion of Malignancy It is indicated when there is a clinical suspicion of lung cancer or other malignancies that may present as peripheral lesions.
  • Assessment of Mediastinal Structures The procedure is useful for assessing the mediastinum and surrounding structures for any pathological changes or abnormalities.

2. Procedure

The procedure involves several key steps that ensure thorough examination and evaluation of the airways and surrounding structures. These steps include:

  • Step 1: Preparation The patient is positioned appropriately, and sedation may be administered to ensure comfort during the procedure. The healthcare provider prepares the necessary equipment, including the bronchoscope and ultrasound probe.
  • Step 2: Insertion of the Bronchoscope The bronchoscope, either rigid or flexible, is inserted through the patient's nose or mouth. It is then advanced through the oropharynx and into the trachea, reaching each mainstem bronchus. Fluoroscopic guidance may be utilized to enhance visualization during this step.
  • Step 3: Visualization of Airways As the bronchoscope is navigated through the airways, the physician inspects for any abnormalities, such as lesions or obstructions. Any findings are documented for further analysis.
  • Step 4: Introduction of the Ultrasound Probe A miniaturized ultrasound probe is then introduced through the flexible bronchoscope. This probe is equipped with a biopsy channel and is specifically designed for transendoscopic endobronchial ultrasound (EBUS).
  • Step 5: Evaluation of Structures Once the ultrasound probe is positioned within the airway, the balloon at the tip of the catheter is inflated to achieve full circular contact with the airway wall. This allows for the visualization of the airway wall and surrounding mediastinum through ultrasonic imaging.
  • Step 6: Comprehensive Assessment The probe is maneuvered along the airway to provide a complete evaluation of the airway and adjacent structures, ensuring that all relevant areas are assessed for any pathological changes.

3. Post-Procedure

After the completion of the bronchoscopy with EBUS, the patient is monitored for any immediate complications or adverse effects. Post-procedure care may include ensuring the patient is stable and recovering from sedation. The healthcare provider will assess the patient's vital signs and may provide instructions regarding any necessary follow-up care or further diagnostic testing based on the findings from the procedure. Patients may experience some throat discomfort or cough following the procedure, which is typically temporary. It is important for the healthcare team to provide clear guidance on signs of potential complications that the patient should report, such as difficulty breathing or excessive bleeding.

Q1 Routine clinical service provided in a clinical research study that is in an approved clinical research study
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).
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).
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).
