The CPT® 2026 code set introduces some of the most significant cardiovascular surgery revisions in years, reflecting advances in interventional techniques, procedural complexity, and the need for clearer procedural classification. These updates affect lower extremity revasculariazation, percutaneous coronary interventions (PCI), thoracic aortic repairs, and coronary lesion reporting — all of which are high-volume in cardiovascular practices.

1. Lower Extremity Revascularization Overhaul (37254–37299)
One of the most transformative changes for 2026 is the complete redesign of leg endovascular revascularization codes. Historically, CPT used codes 37220–37235 for peripheral artery angioplasty/stenting and related interventions. In the 2026 code set, this entire block has been deleted and replaced by an expanded family of ~46 new codes from 37254 through 37299. MedCare MSO
Key structural changes coders must note:
Codes are now organized by vascular territory:
Iliac
Femoral/popliteal
Tibial/peroneal
Inframalleolar
Each family has separate codes for straightforward stenosis (narrowing) versus complex occlusion (complete blockage) procedures. Harmony Healthcare
Access, imaging (e.g., fluoroscopy), and ancillary technologies are generally bundled into the primary procedural code — reducing the need for multiple modifiers but increasing the emphasis on detailed clinical documentation. IMO Health
Atherectomy and specialty device use are specifically delineated within the new code descriptors rather than assumed as part of older umbrella codes. Harmony Healthcare
Why it matters: Without clearly documented lesion type (stenosis vs occlusion), territory treated, and devices used, coders risk selecting incorrect codes that may under- or over-represent the service performed, leading to denials or compliance risks.
2. PCI (Percutaneous Coronary Intervention) Enhancements
The 2026 CPT update also restructures PCI coding to better capture stent complexity and lesion patterns:

A new code, 92930, reports intracoronary stent placement involving two or more distinct coronary lesions, including bifurcation lesions requiring treatment in both main and side branches. American College of Cardiology
Another new PCI code, 92945, reflects chronic total occlusion (CTO) revascularization using combined antegrade and retrograde approaches, often requiring multiple techniques (e.g., stenting, atherectomy). American College of Cardiology
Several add-on branch codes have been deleted (e.g., codes historically used to represent additional vessel segments within a PCI), consolidating reporting under single comprehensive procedural codes per major artery and its branches. SCAI Pro
Legacy codes for intracoronary thrombolysis (92975, 92977) are also removed in favor of current interventional strategies. American College of Cardiology
Clinical documentation implications: Coders must work closely with clinicians to ascertain number of lesions treated, segments intervened, and whether CTO techniques were used — otherwise selecting the proper PCI code (e.g., 92928 vs 92930 vs 92945) can be challenging.
3. Thoracic Aortic and Endograft Adjustments
The 2026 set also includes updates to thoracic endovascular aortic repair (TEVAR) codes (e.g., 33880–33886), with some codes deleted and others revised to reflect anatomical refinements such as coverage of the left subclavian artery and fenestrated/branched grafts. AGS Health
Although these changes are more anatomy-specific and technical, they are important for coders in tertiary care and vascular surgery centers, where accurate TEVAR reporting impacts DRG assignment and reimbursement.
Practical Coding Considerations
Crosswalk old to new: Coders should map legacy series (37220–37235) to the new territorial codes and revise charge masters accordingly.
Clinical specificity: Documentation must explicitly state vascular territories, lesion complexity (stenosis vs occlusion), and technique/device details to support correct code selection.
Training & system updates: EHR templates, charge capture systems, and encoder logic must be updated before Jan 1, 2026, and staff should receive focused education on territory-based vascular coding and PCI restructuring.
These 2026 CPT cardiovascular updates significantly improve procedural granularity and clinical accuracy but require coders to rethink legacy coding patterns and enforce strong documentation practices to ensure correct reporting and compliance
