About 37184: Initial arterial mechanical thrombectomy
Reports catheter-based mechanical removal of clot from the first noncoronary, nonintracranial artery or arterial bypass graft treated.
This service removes thrombus mechanically through a catheter in a noncoronary, nonintracranial artery or arterial bypass graft. It is commonly performed by an interventional radiologist, vascular surgeon, or other qualified specialist in an angiography suite or hospital procedure room, for situations such as acute limb ischemia caused by an arterial blockage or an occluded bypass graft. Fluoroscopic guidance and intraprocedural thrombolytic injections are included in the service.
Report 37184 for the initial treated vessel; 37185 may apply to each additional vessel. The operative or procedure report should identify the artery or graft, the clot-removal method, and the vessel treated first. The code has a 0-day global period, so same-day preoperative and postoperative care are included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral reporting with modifier 50, CMS pays 150%. Assistant-at-surgery services are not paid; co-surgeons are permitted, but team surgery is not.

37184 billing questions
When should 37185 be reported instead?
Use 37184 for the initial vessel treated mechanically. Report 37185 for each qualifying additional vessel treated in the same session.
Does 37184 include fluoroscopic guidance and thrombolytic injections?
Yes. Fluoroscopic guidance and intraprocedural pharmacological thrombolytic injections are included in this thrombectomy service.
How is 37184 different from 37186?
37184 describes primary mechanical thrombectomy of the initial artery or arterial bypass graft. 37186 describes secondary thrombectomy performed with another percutaneous intervention, rather than primary mechanical thrombectomy.
What documentation supports reporting 37184?
Document the treated artery or graft, the mechanical clot-removal work, and which vessel was treated first. The report should support that the service involved a noncoronary, nonintracranial artery or arterial bypass graft.
How does the multiple-procedure reduction affect 37184?
For multiple procedures in one session, CMS pays the highest-valued procedure in full and applies the standard 50% reduction to the others. The reduction depends on which procedure has the highest value.
Can an assistant surgeon be paid for 37184?
No. CMS applies a statutory restriction on assistant-at-surgery payment for this code. Co-surgeons are permitted, while team surgery is not.
