2026 Coding Debrief: Lessons, Questions, and Next Steps-Coding Guidelines for Peripheral Interventions 2026

Coding Guidelines for Peripheral Interventions 2026

Pdf Summary

This document provides detailed guidelines on coverage, indications, and coding for peripheral vascular interventions, particularly non-coronary stenting and percutaneous transluminal angioplasty (PTA).<br /><br />Coverage and Authorization: Coverage varies by payer, and prior authorization must be verified with each payer.<br /><br />Clinical Indications: Non-coronary stenting and PTA are covered when patients have undergone thorough medical evaluation and management of symptoms, and when surgery is a considered alternative. Primary stenting is appropriate when PTA alone is unlikely to yield durable outcomes, including cases with occlusions at high risk for embolization, heavily calcified or eccentric lesions, external compression syndromes, or ostial renal artery stenosis.<br /><br />Specific Vascular Territories and Indications:<br />- Brachiocephalic arteries for flow-limiting stenosis causing ischemic symptoms.<br />- Pulmonary artery for congenital stenosis.<br />- Renal arteries for dissection, aneurysm, >50% stenosis in transplanted kidneys, resistant hypertension, flash pulmonary edema, ischemic nephropathy with chronic kidney disease.<br />- Lower extremity arteries primarily for limb-threatening ischemia; stenting infra-popliteal vessels is rare and must be well justified.<br />- Mesenteric vessels when angioplasty is insufficient, and surgery is the main alternative.<br />- Hemodialysis access graft/fistula stenosis or occlusion.<br />- Venous stenting for superior/inferior vena cava syndrome, thrombotic or compressive conditions.<br /><br />Procedural Sequencing: Interventions may be performed singly or sequentially as necessary to maintain or restore vessel patency.<br /><br />Limitations: Prophylactic stent placement without an objective symptom or functional limitation is considered preventive and not covered by Medicare. Use of investigational device exemption stents may be conditionally covered.<br /><br />Coding Guidelines: Detailed CPT codes for revascularization are listed by vascular territory (iliac, femoral/popliteal, tibial/peroneal, inframalleolar). Codes distinguish straightforward vs. complex lesions, initial vs. additional vessels, and various techniques including angioplasty, stenting, atherectomy, lithotripsy, embolization, thrombectomy, thrombolysis, vena cava filter placement, and intravascular ultrasound (IVUS).<br /><br />Transcatheter Carotid Artery Revascularization (TCAR): Medicare coverage requires FDA-approved devices and embolic protection, specific indications (symptomatic ≥50% stenosis or asymptomatic ≥70%), neurologic assessment, imaging, and shared decision-making with the patient explaining all treatment options.<br /><br />References: Include AMA CPT coding manuals, CMS coverage memos, and SCAI consensus documents.<br /><br />Overall, the guidance emphasizes appropriate patient selection, documented symptom management, detailed coding, and payer verification for reimbursement of peripheral vascular interventions.
