Angioplasty vs. Stent Placement

Question:

Our providers are using a self-expanding scaffold system that features integrated balloon dilation. This device is designed to temporarily support the artery, widening blockages, but the scaffold is retrieved at the end of the procedure, so no permanent implant remains. Such technology represents an innovation for treating peripheral artery disease, especially in cases with complex, calcified narrowing of lower limb arteries. Given that the scaffold is temporary and removed, my coding research indicates this procedure should be reported as angioplasty. Some device vendors suggest billing as stent placement. Is this accurate?

Answer:

For procedures using a temporary self-expanding scaffold with balloon dilation, where the scaffold is removed at the end and no permanent implant remains in the vessel, the intervention should be coded as angioplasty, not a stent placement. Stent placement codes are reserved for conventional stents that remain in the vessel as permanent implants, in accordance with CPT and major coding guidelines. Angioplasty codes are the correct choice when no permanent stent is left behind.
