Ask Dr. Z

Years ago, I seem to recall that we were advised that the ophthalmic artery was skull based, rather than a cerebral vessel. My question is if a physician selects out the internal carotid, and the only vessel he describes is the ophthalmic artery, would we still use 36224 or would we "down code it" to a 36222? Angio is actually done as an aftercare following up a coiling of an ophthalmic aneurysm. The following are the findings. "These images demonstrate stable complete occlusion (Raymond 1, 100%) of the left internal carotid artery ophthalmic segment aneurysm that was treated with primary coiling on 9/7/2017. The internal carotid artery and its branches are patent and preserved."
