CPT® Code 93463

Add-On Code

Pharmacologic agent administration (eg, inhaled nitric oxide, intravenous infusion of nitroprusside, dobutamine, milrinone, or other agent) including assessing hemodynamic measurements before, during, after and repeat pharmacologic agent administration, when performed (List separately in addition to code for primary procedure)

The CPT® Code 93463 refers to the administration of a pharmacologic agent during a heart catheterization procedure, which is a critical intervention used to assess and treat various cardiovascular conditions. This code specifically encompasses the administration of agents such as inhaled nitric oxide, intravenous nitroprusside, dobutamine, milrinone, or other similar medications. The procedure involves a comprehensive evaluation of hemodynamic measurements, which are essential for understanding the patient's cardiovascular status. Prior to the administration of the pharmacologic agent, baseline hemodynamic measurements are obtained to establish a reference point. These measurements may include various parameters such as cardiac index, cardiac output, central venous pressure, mean arterial pressure, preload, afterload, pulmonary artery pressure, pulmonary capillary wedge pressure, pulmonary vascular resistance, right ventricular pressure, stroke index, stroke volume, and systemic vascular resistance. Following the administration of the pharmacologic agent, additional hemodynamic measurements are taken to assess the patient's response to the treatment. This process may involve administering an additional dose of the same or a different pharmacologic agent, with subsequent hemodynamic assessments performed to compare and interpret the results. The physician is responsible for analyzing these measurements and providing a written report detailing the findings. It is important to note that this code is reported separately in addition to the primary procedure of heart catheterization and may only be billed once per session.
