CPT® Code 75885

The procedure described by CPT® Code 75885 involves a specialized imaging technique known as percutaneous transhepatic portography, which is utilized to visualize the portal vein and its collateral veins. This procedure is performed under the supervision of a physician who is responsible for the radiological interpretation of the images obtained. During the process, a catheter is inserted into the portal vein, and a radiopaque contrast material is injected to enhance the visibility of the blood vessels on the radiographs. The physician closely monitors the flow of blood through the portal vein and its collateral pathways, which is crucial for assessing any abnormalities that may be present. Additionally, the procedure allows for the evaluation of varices, which are dilated veins that can occur in the esophagus or stomach, often as a result of increased pressure in the portal vein system. The hemodynamic evaluation component of this procedure includes the measurement of portal vein blood pressure, flow gradients, and flow velocity, providing essential information about the hemodynamics of the portal circulation. The results of the imaging and evaluations are then compiled into a written report by the physician, ensuring that all findings are documented for further clinical decision-making.
