CPT® Code 31730

The CPT® Code 31730 refers to the transtracheal (percutaneous) introduction of a needle wire dilator, stent, or indwelling tube specifically for oxygen therapy. This procedure is commonly known as transtracheal oxygen therapy (TTOT) and is indicated for patients who require long-term oxygen therapy due to various respiratory conditions. The technique involves a minimally invasive approach where a needle wire dilator or stent is inserted through the trachea to facilitate the delivery of oxygen directly into the airway. The procedure begins with the identification of tracheal cartilage landmarks, ensuring precise placement. Following this, the skin is prepared, and a small incision is made at the designated entry site, typically located between the first and third tracheal rings. A guidewire is then introduced, and the tracheal opening is dilated to accommodate the stent, which is temporarily placed to allow the tracheal tract to mature. After approximately one week, once the tract has matured, the stent is removed, and an oxygen delivery catheter is inserted to provide the necessary oxygen therapy to the patient.
