What 37256 covers
This code covers endovascular angioplasty of the initial vessel treated in the iliac vascular territory for a complex lesion. The procedure uses a catheter-based approach to widen a diseased iliac artery, commonly to improve blood flow in a patient with symptomatic peripheral arterial disease. Vascular surgeons, interventional radiologists, and interventional cardiologists may perform it in a hospital angiography or endovascular suite. The code identifies angioplasty treatment; it is not the code for a stent-based treatment pathway.
Choose the complex-lesion code using the applicable CPT lesion criteria, not simply because the procedure used specialized equipment. Document the target vessel, laterality, lesion characteristics supporting complexity, and angioplasty performed. The code includes same-day preoperative and postoperative care under its 0-day global period. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 identifies bilateral treatment and is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose
- 37254Iliac angioplasty
- Both cover angioplasty of the initial iliac-territory vessel. Choose 37254 for a straightforward lesion and 37256 when the lesion meets the complex criteria.
- 37257Iliac angioplasty
- 37256 covers the initial vessel; 37257 is the add-on for each qualifying additional vessel treated for a complex lesion in the iliac territory.
- 37260Arterial stenting
- Both address a complex iliac lesion, but 37256 represents angioplasty treatment and 37260 represents treatment using the stent pathway.
- 37265Vessel angioplasty
- 37265 is complex-lesion angioplasty in the femoral/popliteal territory. Use 37256 for the iliac territory.
37256 billing questions
How do I distinguish 37256 from 37254?
Both report iliac-territory angioplasty of an initial vessel. Use 37256 when the lesion meets the applicable CPT criteria for complex rather than straightforward treatment.
When is 37257 reported with 37256?
37257 is the add-on code for angioplasty of each additional vessel in the iliac territory when the applicable complex-lesion criteria are met. Report it with the appropriate initial-vessel code.
Should routine procedural imaging be billed separately?
Routine imaging and radiological supervision and interpretation associated with the endovascular angioplasty are included. A diagnostic angiogram requires a distinct diagnostic purpose and must meet the applicable reporting criteria.
What documentation supports reporting 37256?
Record the treated iliac vessel, laterality, lesion findings that support the complex classification, and the angioplasty performed. The record should make clear which vessel was treated first in the territory.
How is bilateral treatment handled?
For bilateral treatment, report modifier 50; CMS pays the bilateral procedure at 150%. The standard multiple-procedure reduction applies when other procedures are performed in the same session.
