CPT 31500: Emergency Flexible Endotracheal Intubation
Headline: CPT code 31500: Emergency flexible endotracheal intubation for airway management
Lead: CPT code 31500 denotes the emergency insertion of a flexible tube into the trachea—typically via the mouth—to secure an airway in patients with acute respiratory compromise. The code captures an essential, often lifesaving procedure performed in emergent settings and is central to acute respiratory and resuscitative care nationally.
CPT code 31500 represents an emergency airway management procedure used in scenarios such as acute respiratory failure, severe hypoxemia, respiratory arrest, or compromised airway from trauma or obstruction. Nationally, accurate capture of this code matters for clinical communication, quality measurement, and payment for acute care services.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of the clinical context for use of the code, common co-occurring acute diagnoses, and comparisons to closely related acute procedures. The publication outlines typical sites of service and service type for CPT code 31500, highlights common payer coverage patterns, and references related emergency procedures for clinical coding context. Practical considerations for coding capture, case mix relevance, and alignment with acute care workflows are addressed to inform billing, compliance, and clinical documentation teams.
This summary is written for a national audience and focuses on the code's clinical role, payer relevance, and contextual relations to other emergency interventions.

Billing Code Overview
CPT code 31500 describes the insertion of a flexible tube into the trachea, typically performed through the mouth in an emergency to establish or maintain an open airway in a patient with a compromised airway. This procedure is an emergency airway management intervention.
-
Service type: Emergency airway management (endotracheal intubation using a flexible tube)
-
Typical site of service: Emergency department or other acute/emergent care locations where immediate airway control is required
Clinical & Coding Specifications
Clinical Context
A 62-year-old male arrives to the emergency department via ambulance after sudden collapse at home. On arrival he is unresponsive with absent spontaneous respirations and agonal breathing; pulse is present but oxygen saturation is 70% on non-rebreather. The emergency physician rapidly assesses airway compromise and performs urgent 31500 (flexible endotracheal intubation) via the oral route to secure the airway and provide positive pressure ventilation. Rapid sequence intubation medications are administered, direct laryngoscopy confirms placement, and endotracheal tube position is verified by end-tidal CO2 and chest auscultation. The patient is then placed on mechanical ventilation and admitted to the intensive care unit for management of acute respiratory failure and possible acute respiratory distress syndrome.
Typical clinical workflow:
-
EMS or triage identifies airway compromise and notifies ED team.
-
Airway equipment and personnel prepare for emergent
31500. -
Rapid sequence induction agents and paralytics given as indicated.
-
Provider performs
31500and documents technique, tube size, number of attempts, confirmation methods, and patient response. -
Post-intubation management includes chest x-ray confirmation, ventilator settings, sedation, and admission to an appropriate level of care (ICU).
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
23 | Unusual Anesthesia | Use when emergency intubation occurs without general anesthesia but unusually intensive anesthesia services are required (rare for 31500). |
25 | Significant, Separately Identifiable E/M Service | Use when a separate evaluation and management service is performed on the same date as 31500 (e.g., initial ED visit documented separately). |
52 | Reduced Services | Use when the procedure was attempted but not completed as reported (partial performance). |
53 | Discontinued Procedure | Use when the procedure was started but halted for patient safety before completion. |
59 | Distinct Procedural Service | Use to indicate a distinct procedure or service not normally reported together when appropriate (avoid unbundling). |
62 | Two Surgeons | Use if two surgeons are required and documented for technical reasons during airway procedures. |
76 | Repeat Procedure by Same Physician | Use when the same physician repeats 31500 later the same day for recurrent airway issues. |
77 | Repeat Procedure by Another Physician | Use when a different physician repeats the procedure the same day. |
78 | Unplanned Return to the Operating/Procedure Room by Same Physician Following Initial Procedure for a Related Procedure During the Postoperative Period | Use if patient requires return for airway-related intervention post-procedure. |
79 | Unrelated Procedure or Service by the Same Physician During the Postoperative Period | Use for unrelated services during postoperative period. |
XE | Separate Encounter, Distinct Procedural Service | Use to indicate a distinct encounter for 31500 that is separate from other services on the same day. |
XP | Separate Practitioner, Distinct Procedure | Use when a different practitioner performs 31500 than those performing other services. |
XS | Separate Structure, Distinct Procedural Service | Use when the procedure is performed on a separate anatomical site or structure. |
GZ | Unrestricted Medicare Coverage Criteria Not Met, Item or Service Not Reasonable and Necessary | Use when documentation supports the service but coverage criteria are not met (claims handling). |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207P00000X | Emergency Medicine | Most common specialty performing emergent 31500 in the ED setting. |
207RC0200X | Critical Care Medicine | Performs intubation in ICU or during critical care activations. |
207L00000X | Anesthesiology | Performs airway management in operating room, ED backup, or difficult airway scenarios. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
J96.00 | Acute respiratory failure, unspecified whether with hypoxia or hypercapnia | Primary indication for emergent airway intervention and mechanical ventilation via 31500. |
J80 | Acute respiratory distress syndrome | Severe hypoxemic respiratory failure requiring intubation and mechanical ventilation; 31500 secures airway for ARDS management. |
R09.02 | Hypoxemia | Low oxygen saturation prompting urgent airway protection and intubation with 31500. |
R06.00 | Dyspnea, unspecified | Symptom that may precede respiratory failure and necessitate 31500 when severe and progressive. |
I46.9 | Cardiac arrest, cause unspecified | Cardiac arrest frequently requires airway control with 31500 during resuscitation and post-arrest care. |
