Question:

A physician accesses both common carotid arteries and performed both bilateral cerebral as well as bilateral cervical angiograms. He then went back (same session) and accessed the right internal carotid and performed a second cerebral angiogram. Is the 2nd angiogram (75665) billable with the 75671 (bilateral cerebral angio) w/ modifier 59? The patient has moyamoya so he only accessed the commons before deciding to go into the right internal.
