2) Interventional Radiology involves treatment of injuries/anomalies and disease processes identified by diagnostic tests. This includes Embolizations of aneurysm's and ruptured vessels, Stent placements and Angioplasties, Atherectomies and other such procedures.
So, a CTA is diagnostic test, not an intervention, though it may be part of an Interventional encounter. Angiography is where the two disciplines frequently mesh. As for a list of purely interventional codes vs diagnostic codes, not really there, but any percutaneous codes would most likely fall in the inverventional cateogory. This includes but is not limited to:
Catheter placements 36120-36248, 36000-36012,36481,
Biliary codes 47500-47556
Nephrostomies 50390-50393 (and many more)
Transcatheter therapies 37200-37205, 61623-61635
This should give you an idea.
