31622

Bronchoscopy, Diagnostic, with or without Fluoroscopic Guidance

CPT code 31622 describes a diagnostic bronchoscopy, which can be performed using either a rigid or flexible bronchoscope. This procedure involves the insertion of a bronchoscope, a thin, lighted tube, through the nose or mouth, down the trachea, and into the bronchi and bronchioles of the lungs. The primary purpose of 31622 is for diagnostic evaluation of the tracheobronchial tree and lung parenchyma. During the procedure, the physician visually inspects the airways for abnormalities such as inflammation, tumors, foreign bodies, stenosis, or mucosal changes. While the code itself covers the basic diagnostic visualization, it is often performed with additional diagnostic maneuvers such as bronchial washings, brushings, or biopsies, which are reported with add-on codes. Fluoroscopic guidance may be used during the procedure to assist in navigating the bronchoscope to peripheral lesions or during biopsy procedures, and its use is included within this code. The procedure is typically performed under conscious sedation or general anesthesia, depending on the patient's condition and the scope of the examination. It is a fundamental tool in the diagnosis and management of various pulmonary diseases, including lung cancer, infections, interstitial lung disease, and chronic obstructive pulmonary disease.

Clinical Indications

  • Persistent or unexplained cough
  • Hemoptysis (coughing up blood)
  • Abnormal chest imaging (e.g., suspicious mass, infiltrate, atelectasis, hilar adenopathy, mediastinal adenopathy)
  • Recurrent pneumonia or lung infections
  • Stridor or unexplained wheezing
  • Evaluation of airway obstruction or stenosis
  • Suspected foreign body aspiration
  • Diagnosis and staging of lung cancer
  • Evaluation of unexplained pleural effusion
  • Assessment of tracheal or bronchial injury
  • Surveillance for recurrent cancer or post-transplant complications
  • Identification of infectious agents in immunocompromised patients

Procedure Steps

  1. Patient preparation: Includes obtaining informed consent, NPO status, vital sign monitoring, and administration of conscious sedation or general anesthesia.
  2. Airway anesthesia: Topical anesthetic applied to the pharynx, larynx, and tracheobronchial tree.
  3. Bronchoscope insertion: The bronchoscope is gently inserted through the oral or nasal cavity, past the vocal cords, and into the trachea.
  4. Systematic airway inspection: The physician systematically navigates the bronchoscope to visually inspect the trachea, main bronchi, lobar bronchi, segmental bronchi, and subsegmental bronchi.
  5. Identification of abnormalities: Any lesions, masses, inflammation, foreign bodies, or other anomalies are identified and documented.
  6. Fluoroscopic guidance (if utilized): Real-time imaging may be used to guide the bronchoscope to specific areas, particularly for peripheral lesions.
  7. Specimen collection (if performed, reported separately): Bronchial washings, brushings, or biopsies may be performed.
  8. Bronchoscope withdrawal: The bronchoscope is carefully withdrawn.
  9. Post-procedure care: Monitoring of vital signs, oxygen saturation, and recovery from anesthesia. Instructions regarding potential complications and follow-up care are provided.

Coding Guidelines

  • CPT code 31622 represents the basic diagnostic bronchoscopy, including the insertion, visual inspection, and removal of the bronchoscope.
  • Fluoroscopic guidance, when performed, is considered an inherent part of the diagnostic bronchoscopy and is not separately coded when reported with 31622.
  • If additional diagnostic or therapeutic procedures are performed during the same bronchoscopy session, they should be reported with their respective add-on codes (e.g., 31623 for brushing/washing, 31624 for biopsy, 31625 for transbronchial lung biopsy, 31628 for transbronchial needle aspiration, etc.).
  • Do not report 31622 in conjunction with codes for more extensive bronchoscopic procedures that inherently include the diagnostic component (e.g., 31627, 31629-31646).
  • CPT 31622 includes conscious sedation when performed by the same physician.
  • Modifier 59 may be necessary if a diagnostic bronchoscopy is performed in conjunction with another distinct procedure not typically associated with it, or if performed in a separate anatomical region or during a different encounter on the same day.
