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.

37242 billing questions
How does this differ from 37241?
37242 is for an arterial target; 37241 is for a venous target. Select based on the vessel being embolized, not simply the diagnosis.
When should 37243 or 37244 be used instead?
Use 37243 for embolization directed at a tumor or organ ischemia or infarction. Use 37244 for arterial or venous hemorrhage or a lymphatic leak.
Are roadmapping and procedural imaging separately reported?
No. The code includes the radiological supervision and interpretation, intraprocedural roadmapping, and imaging guidance needed to complete the embolization.
How many units are reported when several arteries are embolized?
Report 37242 once per operative session, even if multiple vessels are treated. Document the treated lesion and vessels in the procedure report.
Can modifier 50 be used for bilateral embolization?
No. The bilateral adjustment is not appropriate for this code. If multiple procedures are performed in the same session, the standard multiple-procedure reduction applies.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
