CPT 31720 Nasopharyngeal & Tracheal Suctioning Reimbursement | OpenPayer

Summary & Overview

CPT 31720: Nasopharyngeal and Tracheal Suctioning

CPT code 31720 denotes nasopharyngeal and tracheal suctioning with a catheter to remove excess secretions or aspirates. This airway clearance procedure is commonly performed in acute care settings to protect the airway and support respiratory function. Nationally, the code is relevant across hospital, emergency, and critical care environments where patients require mechanical or manual airway secretion management.

Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context about the procedure and its typical use cases, operational benchmarks for service lines that perform airway suctioning, and summaries of payer coverage patterns and common billing modifiers associated with procedural coding. The publication also highlights coding considerations for service location and documentation essentials needed to support medical necessity. Data not available in the input is indicated where applicable.

Billing Code Overview

CPT code 31720 describes suctioning of the nasopharynx and trachea to remove excess secretions or aspirates using a suctioning catheter. This procedure is focused on clearing the upper airway and trachea to maintain patency and reduce the risk of respiratory compromise.

Service type: Airway suctioning procedure
Typical site of service: Hospital inpatient or emergency department, critical care units, or other acute care settings where airway management is required

Clinical & Coding Specifications

Clinical Context

A typical patient for 31720 is an adult or pediatric patient with retained upper airway secretions who requires nasopharyngeal and tracheal suctioning to maintain a patent airway. A common scenario is a hospitalized patient on supplemental oxygen or mechanical ventilation who develops copious secretions due to pneumonia, acute respiratory failure, or impaired cough reflex (for example after stroke or sedation). The clinical workflow includes assessment of airway patency and respiratory status by a respiratory therapist or physician, application of appropriate infection control and aerosol precautions, pre-oxygenation if hypoxic, insertion of a sterile suction catheter into the nasopharynx or trachea (via artificial airway if present), aspiration of secretions while monitoring oxygenation and heart rate, and documentation of indications, technique, catheter size, amount and character of secretions, patient response, and any complications. The procedure is typically performed in an inpatient acute care unit, intensive care unit, emergency department, or skilled nursing facility when needed at bedside.
