CPT 31615: Tracheobronchoscopy Through Existing Tracheal Opening
CPT code 31615 identifies a flexible tracheobronchoscopy performed through a previously created tracheal opening, such as a tracheostomy. This procedural code captures visualization of the trachea and bronchial airways via a flexible endoscope passed through the tracheal stoma. Nationally, accurate coding for airway endoscopy through a tracheal opening affects facility and professional billing, patient airway management documentation, and policy interpretation for post-tracheostomy airway surveillance.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and what to expect in coding practice. The publication outlines common modifiers associated with airway endoscopy billing, discusses benchmarking considerations, and highlights policy or reimbursement updates relevant to tracheostomy-related endoscopic services.
This summary provides clinicians, coders, and policy stakeholders with the essential details needed to understand when CPT code 31615 applies and why consistent application matters for national billing and airway-care reporting. Data not available in the input will be noted where applicable in subsequent sections.

Billing Code Overview
CPT code 31615 describes a tracheobronchoscopy performed through an existing tracheal opening. In this procedure, the provider passes a flexible endoscope with a camera through a previously created tracheostomy or tracheal stoma to visualize the trachea and bronchial airways.
-
Service type: Endoscopic airway evaluation (flexible tracheobronchoscopy)
-
Typical site of service: Hospital inpatient unit, hospital outpatient department, or specialized ambulatory surgical center where tracheostomy care and endoscopic airway procedures are performed.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old with a preexisting tracheostomy who presents with increased secretions, hemoptysis, or suspected airway obstruction. The otolaryngology or pulmonary team schedules a flexible tracheobronchoscopy through the existing tracheal stoma to directly visualize the trachea and bronchial tree, evaluate granulation tissue at the stoma, assess for retained secretions, identify endobronchial lesions, or obtain diagnostic samples. The workflow includes preprocedure assessment (history, anticoagulation review, informed consent), topical and/or moderate sedation or monitored anesthesia care, passage of a flexible bronchoscope through the tracheostomy site, targeted inspection and possible suctioning, lavage, or biopsy, and postprocedure monitoring for airway patency and bleeding. Documentation includes indication, technique (through tracheal opening), findings, any interventions performed, specimens collected, sedation and anesthetic agents, and postprocedure condition.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | When billing only the physician interpretation component separate from technical services provided by facility |
52 | Reduced services | When the procedure is partially reduced or not completed as originally planned |
53 | Discontinued procedure | When the procedure is started but halted due to patient condition or safety concerns |
59 | Distinct procedural service | When another unrelated procedure is performed the same day and distinct procedural circumstances apply |
62 | Two surgeons | When two surgeons work together as primary surgeons throughout the procedure |
63 | Procedure performed on infants less than 4 kg | When patient meets neonatal weight criteria and this modifier is required by payer |
76 | Repeat procedure by same physician | When the same physician repeats the procedure later the same day (note: 76 not in provided list; not included) |
78 | Return to operating room for related procedure during postoperative period | When an unplanned return to the OR for a related tracheal/airway procedure occurs |
79 | Unrelated procedure or service by the same physician during the postoperative period | When an unrelated procedure is performed during the global period |
22 | Increased procedural services | When work required to perform the procedure is substantially greater than typical |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207RH0000X | Otolaryngology (ENT) | Common specialist performing airway endoscopy via tracheostomy |
| 207RC0000X | Pulmonary Disease | Pulmonologists perform diagnostic and bronchoscopic airway evaluation |
| 2084P0800X | Critical Care Medicine | Intensivists may perform bedside tracheobronchoscopy in ICU |
| 363LA2200X | Anesthesiology | Provides monitored anesthesia care or general anesthesia for complex cases |

| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
J95.1 | Acute tracheostomy obstruction | Direct indication for tracheobronchoscopy to assess and relieve obstruction |
J95.2 | Acute tracheostomy dysfunction | Evaluated via bronchoscopy through the stoma to identify causes such as granulation tissue |
R04.2 | Hemoptysis, not elsewhere classified | Hemoptysis prompts airway inspection to localize bleeding source |
J98.01 | Acute bronchospasm | Bronchoscopy may be used to evaluate airway when severe unexplained bronchospasm occurs in a tracheostomized patient |
J84.112 | Idiopathic pulmonary fibrosis with progressive interstitial lung disease (example) | Surveillance bronchoscopy with sampling may be performed through tracheal opening for diagnosis or monitoring |
