Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 36901 covers

36901 covers percutaneous entry into an arteriovenous dialysis fistula or graft and diagnostic contrast imaging of the circuit. The study traces flow from the arterial anastomosis and adjacent artery through venous outflow, including central veins, with catheter or needle placement, contrast injections, imaging, and interpretation. Interventional radiologists and vascular surgeons commonly perform it in an angiography suite to evaluate suspected stenosis, poor dialysis flows, prolonged bleeding, or other access dysfunction.

Report 36901 when diagnostic imaging is performed without a circuit intervention. If angioplasty, stenting, or thrombectomy is performed, choose the corresponding intervention code, which includes the diagnostic work; do not separately report 36901 for that circuit. The record should identify the access, findings, imaging extent, and whether treatment occurred. The code has 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 others at 50%. Modifier 50 is inappropriate for this single-circuit service. Medicare does not pay assistant-at-surgery services; co-surgeons and team surgery are not permitted.
