Ask Dr. Z

My question to you is regarding when the physician starts at the access site internal jugular vein (36012) and moves the catheter through the heart down towards the superior vena cava and places the catheter and also images the superior vena cava (36010, 75827), and also performs a congenital right and left heart catheterization (93531), and the exit site of the catheter is back through the internal jugular vein (the access site). Also, while using the access site as the same exit site, the physician decides to perform a selective injection and also image the internal jugular vein (36012, 75825) as he exits the body.  I'm thinking that the codes that need to be selected would be the following: 93531, 75827, 75825, and 36012.  I'm thinking that you would not report code 36010 because it's a major vessel that leads to and from the heart, but can also pick up the image code for the superior vena cava.  Is this correct thinking for facility billing?
