Peripheral vascular intervention

About 37291: Complex tibial atherectomy, additional vessel

Reports complex atherectomy in an additional tibial or peroneal vessel during catheter-based lower-extremity revascularization for peripheral arterial disease.

This add-on code describes atherectomy in an additional tibial or peroneal vessel during endovascular treatment of lower-extremity arterial disease. A vascular surgeon, interventional radiologist, or interventional cardiologist may perform the catheter-based procedure in an angiography or operating suite for limb ischemia caused by obstructive disease. Atherectomy removes or debulks plaque to restore blood flow; angioplasty associated with the atherectomy is part of the revascularization service, rather than a separate angioplasty-only service in that vessel.

Report 37291 only with the appropriate primary procedure, such as 37290 for complex atherectomy in the first vessel. Use it for an additional vessel that meets the complex category’s criteria; document the treated vessels, lesion characteristics supporting that classification, and the atherectomy performed. CMS pays this add-on within the primary procedure’s global period. For a bilateral procedure reported with modifier 50, CMS pays 150%.

37291 billing questions

When is 37291 used instead of 37290?

Use 37290 for the first vessel treated with complex atherectomy. Report 37291 for each additional qualifying vessel in the complex category.

Can 37291 be billed by itself?

No. It is an add-on code and must be reported with an appropriate primary procedure, such as 37290.

Is angioplasty separately reported in the atherectomy vessel?

Angioplasty associated with atherectomy in that vessel is included in the revascularization service; 37291 represents the additional-vessel atherectomy service.

What documentation supports the complex additional-vessel service?

Document the treated tibial or peroneal vessel, the lesion characteristics supporting complex classification, and the atherectomy performed.

How does CMS handle bilateral reporting?

For a bilateral procedure reported with modifier 50, CMS pays 150%. The add-on code must still be reported with its primary procedure.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
