What 37274 covers
This add-on code covers catheter-based atherectomy to remove obstructive plaque in an additional femoral or popliteal artery vessel during endovascular revascularization. Vascular surgeons, interventional radiologists, and interventional cardiologists may perform the procedure in a hospital catheterization lab or an outpatient angiography suite. Angioplasty in the treated vessel is included when performed; this code describes atherectomy without the stent-and-atherectomy combination represented by other codes in the family.
Report it for each qualifying additional vessel after the primary procedure, selecting the complex-lesion pathway based on the documented lesion and the applicable CPT criteria. The procedure note should identify the treated vessels, describe the lesion characteristics supporting complex classification, and document atherectomy in each additional vessel. CMS classifies this as an add-on code: it must be billed with a primary procedure and is paid within that procedure’s global period. For bilateral procedures reported with modifier 50, CMS pays at 150%.

How to choose
- 37273Peripheral atherectomyComplex, initial vessel
- 37273 reports the first vessel treated with complex atherectomy; 37274 reports each qualifying additional vessel.
- 37272Vessel atherectomyEach additional simple artery
- Both describe atherectomy in an additional vessel, but 37272 is for the straightforward-lesion pathway and 37274 for the complex-lesion pathway.
- 37278Stent and atherectomyComplex, each additional artery
- Use 37278 for complex treatment of an additional vessel when atherectomy is combined with stent placement; 37274 describes atherectomy without that combination.
37274 billing questions
When should this code be used instead of 37273?
Use 37273 for the first vessel treated under the complex atherectomy pathway. Use 37274 for each qualifying additional vessel.
Can this code be billed by itself?
No. It is an add-on code and must be reported with a primary procedure for the initial treated vessel.
Is angioplasty separately reported in the same vessel?
Angioplasty performed in the vessel treated with atherectomy is included in this service. The procedure record should distinguish treatment in each vessel.
What documentation supports the complex pathway?
Document the target vessels, the lesion characteristics supporting the complex classification, and the atherectomy performed in each additional vessel.
How is bilateral treatment handled?
For a bilateral procedure reported with modifier 50, CMS applies its 150% payment rule. The code remains an add-on to the 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 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.
