What 37257 covers
This add-on code represents balloon angioplasty of an additional iliac artery vessel in a complex endovascular revascularization. Vascular surgeons, interventional radiologists, and other physicians who perform peripheral arterial interventions may use it for iliac atherosclerotic narrowing or occlusion treated in an angiography or catheterization suite. It describes the angioplasty pathway, rather than the corresponding pathway for treatment with a stent.
Report 37257 for each additional vessel treated when the case meets the billing code family’s complex-lesion criteria; the operative report should identify the iliac vessels treated, the angioplasty performed, and the basis for complex classification. It is an add-on code and must be reported with the primary procedure, typically 37256 for the first complex angioplasty vessel. CMS pays it within that primary procedure’s global period. For bilateral reporting with modifier 50, CMS pays 150%.

37257 billing questions
Can 37257 be reported by itself?
No. It is an add-on for an additional complex iliac angioplasty vessel and is reported with the applicable primary procedure, typically 37256.
Is 37257 reported for each additional lesion or each additional vessel?
The code is for each additional vessel, not each separate lesion within a vessel. The record should identify the vessels treated.
How does 37257 differ from 37255?
Both represent additional-vessel iliac angioplasty. Use 37257 when the lesion meets the family’s complex criteria; 37255 is for the straightforward-lesion pathway.
What documentation supports reporting 37257?
Document the additional iliac vessel treated, the balloon angioplasty performed, and the facts supporting classification as a complex lesion.
How is bilateral treatment reported?
For bilateral treatment, report modifier 50; CMS pays the bilateral procedure at 150%.
