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

What 37242 covers

An interventional radiologist, vascular surgeon, or neurointerventional specialist uses catheter-based techniques to occlude an artery or arterial lesion. Typical indications include congenital or acquired arteriovenous malformations, arteriovenous fistulas, aneurysms, and pseudoaneurysms when the treatment is embolization rather than management of hemorrhage or a tumor. The code covers the embolization intervention and the radiological supervision and interpretation, roadmapping, and imaging guidance needed to complete it.

Choose this code by the treatment target and indication: arterial embolization for a nonhemorrhagic, nontumor condition. The operative report should identify the lesion, target artery or arterial territory, embolization performed, and clinical reason. Report the code once per operative session, even when multiple vessels are treated. It 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 other procedures are subject to the standard 50% reduction. Bilateral adjustment is not appropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
