Procedure Overview
This family describes catheter-based procedures that widen a narrowed or blocked blood vessel using next-generation devices, most notably bioresorbable vascular scaffolds that prop the artery open and then gradually dissolve over months rather than remaining as permanent metal, the way a conventional stent does. Patients typically undergo this when a coronary artery has narrowed enough to restrict blood flow to the heart muscle, causing chest pain or increasing the risk of a heart attack.
The appeal of the newer scaffold technology is that once the vessel has healed and remodeled around it, no permanent foreign material remains, which proponents argue may allow the artery to regain more of its natural flexibility and reduce certain long-term complications tied to permanently implanted hardware.
Anatomy & Axis Detail
Anterior Tibial Artery, Left
On the left, the anterior tibial artery branches from the popliteal artery, threads through the interosseous membrane, and runs down the front of the leg to become the dorsalis pedis artery supplying the dorsum of the foot. This vessel is a frequent target in patients with peripheral arterial disease affecting the below-knee circulation, where long segments of calcified, diffusely narrowed artery can compromise perfusion to the forefoot and toes. Because the anterior tibial artery often represents one of only a few remaining outflow vessels in advanced disease, its patency can be decisive for wound healing and limb preservation. Dilation is generally undertaken to reestablish continuous flow to the foot, and the small vessel diameter and tortuous distal course require careful sizing and technique to avoid dissection or perforation.
Approach: Percutaneous
In New Technology, Percutaneous describes entry into the body via needle or instrument puncture through the skin or a mucous membrane, without a surgical incision, mirroring the same concept in Medical and Surgical. It is distinguished from Open access, which requires a full incision, and from Percutaneous Endoscopic, which adds visualization through the puncture site.
Device / Substance / Technology: Intraluminal Device, Everolimus-eluting Resorbable Scaffold(s)
This value denotes a bioresorbable intraluminal scaffold coated with everolimus, an antiproliferative drug that limits neointimal growth after placement, most familiar from coronary applications. Unlike permanent metallic drug-eluting stents, the scaffold itself gradually resorbs over time, leaving no lasting implant once healing is complete. It is distinguished from other intraluminal device values by combining both the drug-eluting property and full resorbability.
Qualifier: New Technology Group 10
New Technology Group 10 flags a procedure as part of the 2023 batch of add-on codes recognized under the New Technology section. The value itself carries no information about the device or drug involved; that comes from the table, body part, and approach values alongside it. Coders should not confuse it with Group 9 or Group 11, which cover the cohorts approved in the years immediately before and after.
Coding & Documentation
Correct code assignment depends on documentation identifying the specific scaffold or device material, the number of sites or vessels treated, and confirmation that the device qualifies under the applicable New Technology Approval Group rather than being a standard drug-eluting stent. A frequent error is undercounting the number of intraluminal devices deployed, or coding a bioresorbable scaffold placement under the standard Medical and Surgical dilation table simply because the physician's note used generic language like "stent" without specifying the technology.
Commonly Confused With
This family is easily confused with the standard Medical and Surgical coronary artery dilation table, since both describe widening a vessel with a catheter-delivered device. The distinguishing detail is the device itself, a scaffold formally recognized under New Technology criteria versus a conventional metal or drug-eluting stent, so the operative documentation of device type is what separates the two.
