Stenosis of peripheral vascular stent, sequela

This code signifies a narrowing or obstruction that develops in a previously placed stent within a peripheral artery or vein, occurring as a long-term complication or late effect. This stenosis can restrict blood flow, leading to symptoms such as claudication, pain at rest, or tissue loss in the affected limb. It represents a persistent problem arising from the initial stent placement.

Use this code when documenting a patient presenting with symptoms or diagnostic findings consistent with a chronic or late-onset narrowing of a peripheral vascular stent. This applies to situations where the stenosis is no longer an acute event but rather a lasting consequence of the stent implantation. It is appropriate for follow-up encounters after the initial treatment of the stenosis.

• Requires a seventh character "S" to indicate sequela, meaning it is a late effect of the original stent placement.
• Do not use for acute or initial complications of a peripheral vascular stent; those would typically fall under the "A" or "D" seventh characters.
• Consider additional codes for the specific symptoms or manifestations of the stenosis (e.g., intermittent claudication, rest pain, ulceration).
