What 37241 covers

Code 37241 reports catheter-directed closure or embolization of a vein for a nonhemorrhagic problem, such as a symptomatic varicocele, pelvic venous reflux, or a congenital or acquired venous malformation. An interventional radiologist or vascular specialist may deliver coils, plugs, or a sclerosant through a catheter under imaging in an angiography suite or another procedural setting. The target is venous; code selection does not depend on a particular embolic material.

Select this code by the treated venous condition; use the arterial, organ or tumor, or hemorrhage code when that is the treatment purpose. The embolization service includes the imaging guidance, roadmapping, and radiological supervision and interpretation needed to perform it. Document the target vein, indication, access and catheter work, embolic method, and completion findings. The 0-day global period includes same-day preoperative and postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate; Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery reporting are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

37241 billing questions

How is 37241 different from 37244?

37241 is for embolization of a nonhemorrhagic venous target. Use 37244 when the treatment purpose is control of hemorrhage.

Are imaging guidance and roadmapping separately reported?

The imaging guidance, roadmapping, and radiological supervision and interpretation needed to perform the embolization are included in 37241.

Should modifier 50 be appended for bilateral treatment?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How does Medicare apply the multiple-procedure reduction?

For procedures performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.

What documentation supports reporting 37241?

Document the nonhemorrhagic venous indication, target vein, catheter and embolic work, and findings showing the treatment performed.

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.
