CPT® Code 75893

Venous sampling through catheter, with or without angiography (eg, for parathyroid hormone, renin), radiological supervision and interpretation

The CPT® Code 75893 refers to the procedure of venous sampling through a catheter, which may include angiography, accompanied by radiological supervision and interpretation. This procedure is typically performed to obtain blood samples from specific organs, which can be crucial for various diagnostic purposes, such as measuring levels of parathyroid hormone or renin. During this process, a physician utilizes a catheter to access a selected vein, allowing for the collection of blood samples that are essential for further analysis. The term 'radiological supervision and interpretation' indicates that the physician is responsible for overseeing the imaging aspects of the procedure, ensuring that the catheter is correctly placed and that the necessary images are captured for accurate assessment. The physician not only supervises the placement of the catheter but also monitors the flow of blood through the veins, which is vital for understanding the organ's blood supply. Additionally, if required, a radiopaque contrast agent may be injected to enhance the visibility of the vascular structures during angiography. After the procedure, the physician reviews the obtained radiographs and provides a comprehensive written interpretation of the findings, which is essential for guiding further clinical decisions.
