Summary & Overview
CPT 31605: Emergency Tracheostomy via Cricothyroid Membrane
CPT code 31605 captures an emergency surgical airway procedure in which an incision through the cricothyroid membrane exposes the trachea and creates an opening for ventilation. As an acute, potentially life‑saving intervention, this code is used in time‑sensitive situations where securing the airway is critical. Nationally, accurate use of this code affects clinical documentation, hospital billing, and emergency care quality reporting.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for 31605, common sites of service, and the implications for acute care coding. The publication summarizes typical billing considerations, common modifiers observed in practice, and points of attention for claims submission and audit readiness.
This resource is intended to provide clinicians, coding professionals, and revenue cycle staff with a clear description of the procedure represented by CPT code 31605, the settings where it is commonly performed, and the types of payer policies and documentation practices that commonly intersect with emergency airway procedures.

Billing Code Overview
CPT code 31605 describes an emergency tracheostomy performed through an incision of the cricothyroid membrane to establish an airway. This procedure involves making an incision to expose the trachea (windpipe) and creating an opening to permit ventilation when other airway access is compromised.
-
Service type: Emergency surgical airway procedure (cricothyroidotomy/tracheostomy)
-
Typical site of service: Emergency department, operating room, or other acute care setting where an immediate airway is required.

Clinical & Coding Specifications
Clinical Context
A patient arrives to the emergency department in acute respiratory distress after a traumatic crush injury to the neck with airway obstruction from soft tissue swelling and blood. Attempts at endotracheal intubation are unsuccessful due to distorted anatomy and rapidly worsening oxygenation. The on‑call otolaryngology or trauma surgeon, in coordination with the emergency medicine team and anesthesiology, performs an emergent cricothyroidotomy (surgical airway) to rapidly establish a patent airway. The procedure is performed at the bedside in the emergency department or in the operating room when immediate transport is possible. Post‑procedure, the patient is stabilized, oxygenation confirmed, and plans are made for conversion to a formal tracheostomy if long‑term airway access is anticipated. The clinical workflow includes rapid airway assessment, informed emergent consent when possible, preparation of sterile field and airway equipment, performance of the incision through the cricothyroid membrane, placement of the airway device, securing the airway, documentation of indications and technique, and handoff to critical care for ongoing management.
