CPT® Code 31605

The CPT® Code 31605 refers to an emergency tracheostomy procedure performed through the cricothyroid membrane. This procedure is typically indicated in urgent situations where immediate access to the airway is necessary, such as in cases of severe airway obstruction or respiratory distress. The cricothyroid membrane is a thin membrane located between the cricoid and thyroid cartilages in the neck, and accessing the airway through this membrane allows for rapid ventilation. The procedure is performed on patients aged two years or older, and it involves specific steps to ensure that the airway is established safely and effectively. The physician must carefully identify anatomical landmarks, administer local anesthesia, and make precise incisions to avoid damaging surrounding structures, particularly the vocal cords. This emergency intervention is critical in life-threatening situations where traditional intubation may not be feasible, providing a temporary airway until a more permanent solution can be established.
