During an EVAR I embolized the internal iliac. Can I code separately for that?
Yes. The internal iliac is outside the target zone of the endograft, so an intervention in that vessel may be reported separately. You would bill 37242-59 for the embolization. If the catheterization of the internal iliac is also documented, report 36246 for the second order catheterization. Remember, if you catheterized the aorta with bilateral catheters (36200-50) one of those non-selective catheter placements will now be bundled into the selective catheterization, 36246.
