Neurointerventional radiology
About 61623: Temporary arterial balloon occlusion test
Reports temporary endovascular occlusion of a head or neck artery, commonly to assess collateral circulation before a planned permanent vessel occlusion.
A neurointerventional physician uses an endovascular balloon or another temporary occlusion technique to block flow in a head or neck artery while assessing whether collateral circulation can maintain perfusion. A common use is testing tolerance to temporary internal carotid artery occlusion before a planned vessel sacrifice. The service is typically performed in a hospital angiography suite with imaging guidance; the code includes the associated radiological supervision and interpretation.
Report the code when temporary arterial occlusion is actually performed, not for balloon angioplasty or permanent embolization. Documentation should identify the artery, temporary occlusion method, purpose of the test, and imaging findings. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

Use 61623 for temporary arterial occlusion, such as testing collateral circulation. Code 61630 describes balloon angioplasty to treat an intracranial narrowing.
Does the code include imaging supervision and interpretation?
Yes. The service includes the radiological supervision and interpretation associated with the temporary occlusion.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not use modifier 50.
How does the multiple-procedure reduction affect payment?
For procedures performed in the same session, the highest-valued procedure is paid in full, and the other procedures are subject to the standard 50% reduction.
Can an assistant surgeon or co-surgeon be paid?
Assistant-at-surgery payment is restricted for this code. Co-surgeons and team surgery are not permitted.
What should the procedure note document?
Identify the artery and temporary occlusion method, explain the clinical purpose—such as assessing collateral circulation—and record the imaging findings.
