CPT 31725: Fiberscope-Assisted Tracheobronchial Suctioning
CPT code 31725 covers bedside tracheobronchial suctioning using a fiberscope to aspirate and remove excess secretions from the tracheobronchial tree. The code captures a targeted, endoscopic suctioning procedure commonly performed in acute care settings—most often at the bedside in hospital wards or intensive care units—when conventional suctioning is inadequate or when direct visualization is required. Nationally, accurate reporting of this code matters for appropriate resource tracking, clinical documentation, and alignment of procedure reporting across payers.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for 31725, typical sites of service, and the payment and coding considerations that are commonly relevant to these payers. The publication summarizes available benchmarks and common modifier usage where applicable, highlights documentation elements that support billing, and outlines the clinical scenarios in which fiberscope-assisted suctioning is typically reported. Data not available in the input is noted where applicable.

Billing Code Overview
CPT code 31725 describes a bedside tracheobronchial suctioning procedure performed with a fiberscope. In this procedure, the provider introduces a suctioning catheter via a fiberscope to remove excess secretions or aspirates from the patient’s tracheobronchial tree.
-
Service type: Bedside endoscopic tracheobronchial suctioning using a fiberscope
-
Typical site of service: Hospital bedside, intensive care unit, or other inpatient/acute care setting where bedside bronchoscopic suctioning is performed
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult admitted to an acute care hospital with copious tracheobronchial secretions causing airway obstruction or impaired ventilation. The patient may be intubated or have a tracheostomy and is experiencing respiratory distress, hypoxemia, retained secretions, or difficulty weaning from mechanical ventilation. The bedside team (pulmonologist, critical care physician, or otolaryngologist) performs tracheobronchial suctioning via flexible fiberoptic bronchoscope introduced through the endotracheal tube or tracheostomy tube to visualize the airways and remove obstructing secretions or mucus plugs.
The clinical workflow includes pre-procedure assessment (vital signs, oxygenation, coagulation status), informed consent when feasible, equipment setup (sterile suction catheter, flexible fiberscope, suction canister), administration of supplemental oxygen and suctioning under visualization, and post-procedure monitoring for oxygenation, bleeding, or bronchospasm. Documentation includes the indication, technique (fiberoptic-guided suctioning), findings, amount/character of secretions removed, patient tolerance, and any complications.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the work, time, or complexity is substantially greater than typical for 31725 (requires documentation). |
23 | Unusual anesthesia | Use when general anesthesia was required for the suctioning procedure due to patient condition. |
26 | Professional component | Use when reporting only the physician’s professional interpretation component separate from technical services. |
52 | Reduced services | Use when the procedure was partially reduced or not completed as originally intended. |
53 | Discontinued procedure | Use when the procedure was started but then discontinued for patient safety or other documented reasons. |
57 | (Not in provided list) | Data not available in the input. |
59 | (Not in provided list) | Data not available in the input. |
QK | Medical direction of two, three, or four CRNAs by a physician | Use when physician medically directs multiple CRNAs for anesthesia related to the procedure. |
QX | CRNA service with medical direction by a physician | Use when a CRNA provides anesthesia under physician medical direction. |
QY | Service rendered by an anesthesiologist or CRNA with medical direction | Use when anesthesia services meet the QY criteria. |
ET | Self-audit | Use when an audit or edit indicator applies (system-specific; document per payer instructions). |
FY | State-specific modifier (fetal procedures) | Use only if payer recognizes this state-specific modifier per local rules. |
SH | Senior physician service | Use when service is performed by a senior physician in teaching settings as defined by payer rules. |
TC | Technical component | Use when reporting only the technical component of the service. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207RP0000X | Pulmonology | Pulmonologists commonly perform fiberoptic-guided airway suctioning and bronchoscopic airway clearance. |
2084P0200X | Critical Care Medicine | Intensivists perform bedside fiberoptic airway procedures in ICU settings. |
2084P0205X | Neurocritical Care (or similar critical care subspecialty) | Subspecialists in critical care for complex airway management. |
208600000X | Otolaryngology | ENT specialists perform fiberoptic airway suctioning in complex head and neck airway cases. |
363LP0800X | Respiratory Therapist (if billable under supervision) | Respiratory therapists assist and may perform suctioning under protocol but typically do not bill 31725 as physician procedure. |

J18.9 | Pneumonia, unspecified organism | Patients with pneumonia often have increased secretions and may require fiberoptic-assisted suctioning for clearance. |
R09.02 | Hypoxemia | Low oxygen saturation can be associated with retained secretions requiring suctioning. |
