The physician performs a bilateral selective subclavian angiogram with bilateral vertebral angiography and bilateral selective carotid angiography. He describes the catheter placement in both subclavian arteries and angiographic findings as: right and left subclavian arteries are unremarkable; vertebral arteries are patent. Because the catheter must go past the innominate on the right side into the subclavian, is it appropriate to also assign a second-order selective catheterization code (eg, 36216 ) in addition to code 36222 with modifier 50 appended for the carotids? ...

Article Overview
This coding article explains a bilateral angiography scenario involving the carotid, subclavian, and vertebral vascular territories. It is relevant to medical coders and billing professionals who work with vascular imaging and selective catheterization documentation. The article focuses on how the reported procedure is represented in CPT terms and addresses whether additional catheterization reporting is supported in this type of case.
Why This Topic Matters
Accurate reporting of complex bilateral angiography depends on recognizing which vascular territories and catheter placements are already included in the reported services. This article helps readers understand the scope of the documented procedure and the general coding context for bilateral vascular imaging.
