Introduction of intracatheter or catheter into renal pelvis for drainage and/or injection, percutaneous, radiological supervision and interpretation

The procedure described by CPT® Code 74475 involves the introduction of an intracatheter or catheter into the renal pelvis, which is the area of the kidney that collects urine before it moves to the bladder. This procedure is performed percutaneously, meaning that it is done through the skin, typically using a needle to access the kidney. The primary purpose of this procedure is to facilitate drainage of fluid that may have accumulated in the kidney or to allow for the injection of a therapeutic substance directly into the renal pelvis. The physician performing this procedure utilizes radiological supervision, which involves taking and interpreting a series of X-ray images to guide the catheter placement accurately and ensure that it is positioned correctly within the kidney. This imaging is crucial for the safety and effectiveness of the procedure, as it helps the physician visualize the anatomy and any potential complications that may arise during the catheter insertion process.
