Stenosis of other vascular prosth dev/grft, sequela

This code signifies a narrowing or obstruction that develops in a previously implanted artificial blood vessel, graft, or other vascular device. This stenosis is a long-term complication, occurring after the initial treatment of the underlying condition. It indicates a persistent or late effect of the device malfunction.

Use this code when documenting a patient presenting with symptoms or findings related to a chronic or late-onset narrowing of an artificial vascular implant. This typically applies to follow-up encounters where the stenosis is being managed, or its long-term effects are being addressed, rather than the initial acute complication.

• Requires an additional code to identify the specific type of vascular device (e.g., bypass graft, stent).
• The "S" seventh character indicates a sequela, meaning it's a late effect of the original complication.
• Do not use for acute or initial complications of the device; those would typically use an "A" or "D" seventh character.
