What 37273 covers
This code represents endovascular atherectomy to restore flow through a complex lesion in a femoral or popliteal artery. It is typically performed by a vascular surgeon, interventional radiologist, or interventional cardiologist using catheter-based equipment. Balloon angioplasty in the treated vessel is included when performed. The code identifies the initial vessel treated with complex atherectomy; it is not the code for a simple atherectomy or for treatment that includes stent placement.
Select the complex level using the applicable CPT criteria, and document the target artery, laterality, lesion characteristics supporting that level, and the atherectomy performed. Use the corresponding additional-vessel code when another qualifying vessel is treated. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. With multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 for bilateral treatment is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

37273 billing questions
How is complex atherectomy distinguished from simple atherectomy?
Use the CPT criteria for the complex level rather than relying only on the operator's description. The record should support the lesion characteristics that qualify the treated vessel as complex.
Is balloon angioplasty separately reported in the treated vessel?
Angioplasty performed in the same vessel as this atherectomy is included in the revascularization service. Do not report a separate angioplasty code for that work.
When is 37274 used with this code?
37274 identifies each additional vessel treated with complex atherectomy. Use 37273 for the initial qualifying vessel and document each treated vessel.
What if a stent is also placed in the treated vessel?
Use the code describing the applicable stent-and-atherectomy treatment rather than reporting this atherectomy-only code for that vessel. For complex treatment, compare with 37277.
How is bilateral treatment reported?
Report bilateral treatment with modifier 50. CMS pays the bilateral procedure at 150%.
Can an assistant surgeon be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code.
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.
