CPT® Code 99191

Assembly and operation of pump with oxygenator or heat exchanger (with or without ECG and/or pressure monitoring); 45 minutes

The CPT® Code 99191 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 involves the setup and management of the pump system, which may include additional monitoring capabilities such as electrocardiogram (ECG) and pressure monitoring. The time allocated for this procedure is specifically 45 minutes. It is important to note that this code is applicable for each hour of assembly, allowing for accurate billing based on the duration of the procedure. For treatments that last three-quarters of an hour, this code is appropriate, while for those lasting half an hour, CPT® Code 99192 should be utilized. This distinction is crucial for proper coding and reimbursement in medical billing practices.
