For portal vein catheterization followed by insertion of a transvenous intrahepatic portosystemic shunt, what code is reported?

The correct code for portal vein catheterization followed by the insertion of a transvenous intrahepatic portosystemic shunt is 37182. This code specifically describes the procedures involving the creation of a portosystemic shunt using a transvenous approach, which involves accessing the portal vein and establishing a connection to the systemic venous circulation.

In this context, the procedure focuses on managing conditions such as portal hypertension. The unique nature of this invasive technique, which includes both catheterization of the portal vein and the shunt insertion, justifies the use of this specific code.

Other options represent unrelated procedures. For instance, 63055 pertains to spinal surgeries, 27750 deals with surgeries on the hip, and 19120 is for mastectomy procedures. These codes do not relate to vascular interventions or the creation of shunts within the portal venous system, making them inappropriate for this specific scenario. Understanding the exact procedural details and their correlating codes is crucial for accurate CPT coding in surgical practices.
