CPT® Code 99190

The CPT® Code 99190 refers to the assembly and operation of a pump that is equipped with either an oxygenator or a heat exchanger. This procedure is typically performed by a physician and is crucial in various medical settings, particularly in situations requiring extracorporeal circulation, such as during certain surgical procedures or in critical care environments. The code encompasses the entire process of setting up and managing the pump, which may include monitoring the patient's heart activity through an electrocardiogram (ECG) and/or measuring blood pressure, although these monitoring functions are not mandatory for the procedure to be coded under 99190. It is important to note that this code is billed for each hour of service provided. For shorter durations of treatment, there are specific codes available: CPT® Code 99191 is used for treatment lasting three-quarters of an hour, while CPT® Code 99192 is designated for treatment lasting half an hour. This structured approach to coding ensures that healthcare providers are accurately reimbursed for the time and resources dedicated to patient care during these complex procedures.
