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.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
59 | Distinct procedural service | Use when 31720 is a separate, independent suctioning procedure distinct from other services performed on the same day. |
52 | Reduced services | Use when suctioning is attempted but not completed to the usual extent due to patient condition. |
53 | Discontinued procedure | Use when the procedure is started but terminated for patient safety before completion. |
76 | Repeat procedure by same physician | Use when 31720 is repeated later the same day by the same provider (note: 76 is not in raw list; not used). |
62 | Two surgeons | Use when two qualified surgeons/physicians work together during a complex airway procedure requiring suctioning (rare). |
78 | Return to operating/procedural room for related procedure by same physician | Use when patient returns to procedure area for additional airway suctioning after an initial procedure. |
26 | Professional component | Use when billing only the professional component if the technical component is billed elsewhere (rare for bedside suctioning). |
TC | Technical component | Use when billing only the technical component (facility) separate from professional component. |
59 | Distinct procedural service | Use when 31720 is a separate, independent suctioning procedure distinct from other services performed on the same day. |
QK | Medical direction of two, three, or four concurrent anesthesia cases | Not typically applicable but listed among common modifiers. |
