CPT® Code 33961

Deleted

Prolonged extracorporeal circulation for cardiopulmonary insufficiency, represented by CPT® Code 33961, refers to the use of extracorporeal membrane oxygenation (ECMO) as a therapeutic intervention for patients experiencing reversible cardiac and/or respiratory failure. ECMO is a sophisticated medical procedure that employs a cardiopulmonary bypass circuit to temporarily take over the function of the heart and lungs, thereby providing critical support to patients whose conditions have not improved with standard medical therapies. This procedure is applicable to a diverse patient population, including neonates, children, and adults, who are facing severe cardiac and/or respiratory challenges. During the ECMO process, the physician plays a vital role in continuously monitoring the patient's condition and making necessary adjustments to the ECMO settings. This is done to ensure optimal support for both cardiac and respiratory functions, which is assessed through various tests, including blood gas analyses and clinical observations. It is important to note that CPT® Code 33961 is specifically designated for billing purposes for each subsequent day of ECMO maintenance following the initial day, which is coded using CPT® Code 33960.
