  • Gain knowledge of key terms and phrases
  • Practice – participate in case examples and exercises
what is interventional radiology
What is Interventional Radiology

Interventional radiology is the non-surgical treatment using radiologic imaging, with contrast, to guide instruments (catheters, balloons, etc) through the body’s blood vessels and other organs. This type of procedure is done for both diagnostic and therapeutic procedures and is usually done on an outpatient basis.

Some common types of procedures done in interventional radiology include:

  • Angiography
  • Angioplasty
  • Atherectomy
  • Stent insertion
  • Biopsies
  • Occlusion procedures
interventional radiology terms
Interventional Radiology Terms
  • Angiography – Pictures taken of a blood vessel
  • Antegrade – with the flow
  • Bifurcation – a “splitting” or “forking” of vessels into two separate vessels
  • Bovine Arch – anomaly in the vessels coming off the aortic arch where the left common carotid actually comes off the right innominate artery instead of off the aorta
  • Catheter – instrument used in most percutaneous interventional radiology procedures
  • Contralateral – opposite side
  • First order – primary vascular branch
interventional radiology terms cont
Interventional Radiology Terms (cont)
  • Great Vessels – those vessels that come off the aortic arch – in normal anatomy; the brachiocephalic, common carotid, and left subclavian
  • Guiding angiogram – imaging taken of vessel that the catheter is in so that the physician can verify where they’re at and where they still need to go
  • Ipsilateral – same side
  • Non-select catheter placement – catheter positioned in the aorta (from anywhere outside of the aorta) or placement in the access vessel itself without manipulation into another vessel
interventional radiology terms cont6
Interventional Radiology Terms (cont)
  • Retrograde – against the flow
  • Select catheter placement – catheter that is threaded:
    • Into a vessel off the vessel accessed
    • The aorta
    • Vena Cava
  • Vascular families – each separate set of vessels:
    • Off the vessel accessed
    • Off the Aorta
    • Off the Vena Cava
some simple coding rules
Some Simple Coding Rules
  • Code to the final catheter placement per vascular family
  • Do not code to where the wire is placed
  • Select catheter placement always takes precedence over non-select unless a second access is obtained
  • Code each vascular family separately
  • Code only one select catheter placement from each vascular family (36215-36217 & 36245-36247)
  • Make sure the proper codes are being used for catheter placement in regards to anatomy
    • Above the diaphragm 36215-36218
    • Below the diaphragm 36245-36248
key words and phrases to look for
Key Words and Phrases to Look for
  • Roadmapping – this is NOT imaging
  • Verification of catheter placement is NOT imaging
  • In, engaged, cannulated, in the mouth of, in the orifice of, in the ostia; these describe the catheter being IN the vessel the physician is referring to or maybe getting ready to image
  • At, near, to, proximal to; these are words that describe the catheter NOT being in the vessel the physician is referring to

cpt code 75774
CPT Code 75774
  • To code/charge CPT 75774, it is required that additional imaging beyond the basic exam is performed after an additional level of catheter selectivity is documented for the exam.
  • It is not appropriate to assign when images are obtained to “complete” the initial “runoff” exam, i.e. step-table, even if more selective catheter placement is performed.
  • Documentation of the clinical indication for needing to do so, e.g. poor visualization, occlusive disease, anatomical variants, etc., as well as imaging findings is also required.
case example rules
Case Example Rules
  • Unless otherwise specified, all access is through the femoral artery
  • All findings are assumed reported unless otherwise stated

Case Examples (cont)

20. Local anesthesia provided to patient before procedure began. Right common femoral artery was prepped and draped in a sterile fashion then accessed with small nick incision. Multiple attempts were made to advance the wire and catheter but because of the occluded right external iliac artery, catheters were withdrawn and attention turned to the left groin. Using the same technique as the right groin, access into the left femoral artery was obtained. Catheter was then threaded up into the abdominal aorta to the level of the renal arteries.

Aortography was performed with run-off down to the bilateral common femorals

Images were obtained, after which all catheters were withdrawn and hemostasis obtained through manual pressure.

case examples cont24
Case Examples (cont)

21. From R groin access, an abdominal aortogram is performed via cath placement in the abdominal aorta and injection above the renal arteries w/ findings documented followed by BLE angiography via cath movement to the bifurcation and injection revealing an abnormality of the R popliteal artery. The catheter is “pulled back” into the R femoral artery and additional injection or imaging is performed of the popliteal artery.

case examples cont25
Case Examples (cont)

22. Utilizing Seldinger technique and 1% Xylocaine for local anesthesia, a #5 French pigtail catheter was inserted via the right common femoral artery and advanced into the aortic arch where arch aortography was performed. Bilateral carotid arteriograms and bilateral vertebral arteriograms were performed after selective catheterization. The following catheters were utilized: JB2 in the right common carotid, Simmons I in the left common carotid, and a #5 French vertebral catheter in both vertebral arteries. The catheters were removed and hemostasis obtained. The patient tolerated the procedure well. There were no apparent complications (cont)

case examples cont26
Case Examples (cont)
  • Arch aortography: Shows normal orientation of the great vessels , with the left common carotid notably tortuous proximally. No other focal abnormalities are seen.
  • Right carotid arteriogram: There is approximately 40% narrowing of the junction of the right common carotid with the internal carotid from a small posterior located plaque. Otherwise, the right extracranial internal carotid appears unremarkable. The right external carotid appears unremarkable. There is noted a 7 x 6.5 mm aneurysm originating form the distal internal carotid near the level of the origin of the ophthalmic artery. The aneurysm projects medially and posteriorly. The right anterior and middle cerebral arteries appear unremarkable.
  • Left carotid arteriogram: No focal abnormalities are seen. No extracranial or intracranial abnormalities are evident. No aneurysms are identified.
  • Left vertebral arteriogram: No focal abnormalities are seen. No aneurysm is evident. The basilar tip is unremarkable. No aneurysms are seen around the region of the posterior inferior cerebellar arteries.
  • Right vertebral arteriogram: No focal abnormalities are identified. No aneurysms are seen. The basilar tip is unremarkable
