Stenosis of other cardiac prosth dev/grft, sequela

This code signifies a long-term complication involving the narrowing or obstruction of a previously implanted cardiac device, implant, or graft, excluding prosthetic heart valves. This stenosis is a residual effect of the original device malfunction or a related issue that occurred in the past.

Use this code when documenting a patient presenting with symptoms or findings related to the persistent narrowing of a non-valvular cardiac implant, such as a coronary stent, pacemaker lead, or vascular graft, where the initial acute event has resolved. This applies to follow-up encounters for chronic or late-onset stenosis.

• Requires a seventh character 'S' for sequela, indicating a complication or condition that is the late effect of an earlier problem.
• Always sequence this code after the code(s) for the specific manifestation(s) of the stenosis (e.g., angina, heart failure).
• Ensure documentation clearly links the current stenosis to a previously implanted cardiac device, implant, or graft, and specifies it is not a prosthetic heart valve.
