What 36906 covers

This service treats a clotted hemodialysis access circuit, such as an arteriovenous fistula or graft, by removing clot mechanically or using thrombolytic infusion and dilating a narrowing in the central venous outflow with a balloon. Interventional radiologists, vascular surgeons, and clinicians who perform dialysis-access interventions commonly provide it in an angiography suite or hospital procedure room. Imaging used to guide and assess the treatment is included in the service.

Select this code when the session includes clot treatment and balloon angioplasty of the central dialysis segment. The report should identify the access circuit, the clot treatment performed, the central narrowing treated, and the imaging findings supporting the intervention. Same-day preoperative and postoperative care is included in the 0-day global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment is barred by statute; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
