Stenosis due to other internal prosth dev/grft, sequela

This code signifies a narrowing or stricture of a bodily passage or vessel that has developed as a long-term complication (sequela) of an internal prosthetic device, implant, or graft. This stenosis is not due to mechanical complications like displacement or erosion, but rather a physiological response to the presence of the device.

Use this code when a patient presents with a chronic or late-onset stenosis directly attributable to a previously implanted medical device, such as a stent, shunt, or mesh. This applies when the initial acute phase of the complication has passed, and the stenosis is a persistent or recurring issue.

• Always code the specific type of stenosis (e.g., esophageal, urethral) as a primary diagnosis if known, followed by this code as a secondary diagnosis.
• Ensure documentation clearly links the stenosis to the presence of the internal prosthetic device, implant, or graft.
• This code is for sequela, meaning the initial complication has resolved, and the stenosis is a residual effect; do not use for acute or initial complications.
