Some of the most sweeping changes to interventional radiology CPT coding since 2011 became effective on January 1, 2026. If you’re wondering what to expect in the year ahead, here’s a high-level summary of the coding updates your IR team needs to know.
The two main areas impacted by the 2026 CPT changes are:
- Lower Extremity Revascularization
- Thoracic Endovascular Aneurysm Repair (TEVAR)
At a Glance: What’s Changing in 2026?
| Lower Extremity Revascularization | TEVAR |
|
· 16 deleted codes · 46 new codes · Revised guidelines · New definitions for straightforward vs. complex lesions · Addition of inframalleolar territory |
|
Lower Extremity Revascularization Updates
The lower extremity revascularization code set has been significantly restructured. Sixteen codes in the 37220–37235 range were deleted and replaced with 46 new codes (37254–37299). This overhaul was designed to reflect modern procedural complexity and expand reporting options, including:
- Inclusion of revascularization procedures in the ankle and foot (inframalleolar territory)
- Differentiation between straightforward lesions (stenosis) and complex lesions (occlusion)
- Addition of a second vessel in the femoral-popliteal territory, allowing for reporting multiple interventions in a single leg
- New CPT codes for intravascular lithotripsy (IVL) in the iliac and fem-pop territories
Codes are still assigned based progressive hierarchies based on the complexity of the procedure performed (angioplasty, stenting, and atherectomy) and only one intervention can be coded per vessel in that territory.
One important note: HCPCS codes for revascularization with IVL remain available for hospital reporting:
- C9764–C9767 (iliac/fem-pop)
- C9772–C9775 (tibioperoneal)
However, the new CPT codes now support professional fee (pro-fee) reporting of IVL, where previously an unlisted CPT code was often required.
TEVAR Code Updates
TEVAR codes have also been updated to simplify reporting and align more closely with EVAR and FEVAR coding structure.
In 2026, TEVAR codes were revised to eliminate component reporting, meaning the radiology supervision and interpretation (S&I) codes are no longer reported separately from the surgical component.
Below is a breakdown of which TEVAR-related codes were added, revised, or deleted:
| New CPT Code | Revised CPT Codes | Deleted CPT Codes |
| 33882, Thoracic branch endograft (TBE) | 33880, TEVAR covering left subclavian artery | 33884 |
| 33881, TEVAR not covering the left subclavian artery | 33889 | |
| 33883, Delayed placement of proximal extension prosthesis, not involving the left subclavian artery | 33891 | |
| 33886, Delayed placement of distal extension prosthesis | 75956-75859 |
