Diagnostic angiography
About 36224: Selective internal carotid angiography
Reports selective catheter angiography of one internal carotid artery when images document both the ipsilateral extracranial and intracranial circulation.
A physician advances a catheter selectively into an internal carotid artery and injects contrast to image that side’s extracranial and intracranial carotid circulation. Arch and cervical carotid imaging may be included when performed. Neurointerventional and diagnostic radiologists commonly perform the study in a hospital angiography suite; the service represents diagnostic imaging, not catheter placement alone.
Report the code when the record supports selective internal carotid catheterization, imaging of both circulation regions, and an interpretation of the findings. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. CMS does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

36224 billing questions
Does catheter placement alone support 36224?
No. The study includes angiography of the ipsilateral extracranial and intracranial carotid circulation; catheter placement without that imaging does not describe the service.
When should 36223 be considered instead?
Use 36223 when the selective catheter position is in the common carotid or innominate artery and the documented imaging meets that code’s criteria. 36224 is for selective placement in the internal carotid artery.
What documentation supports reporting 36224?
Document the side, selective internal carotid catheter position, imaging of both the ipsilateral extracranial and intracranial circulation, and the angiographic interpretation.
How is bilateral internal carotid angiography paid?
CMS identifies this as a bilateral procedure; reporting modifier 50 is paid at 150%.
Are same-day services included in the global period?
Yes. The 0-day global period includes same-day preoperative and postoperative care.
Can an assistant or co-surgeon be reported?
CMS does not pay an assistant at surgery for this procedure. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
