Thrombosis due to nervous system prosth dev/grft, sequela

This code signifies a blood clot (thrombosis) that has developed as a long-term consequence or complication of a previously implanted or grafted device within the nervous system. This includes devices such as shunts, stimulators, or other neuroprosthetics. The thrombosis is not an acute event but rather a residual effect or late complication.

Use this code when documenting a patient presenting with thrombosis that is directly attributed to a nervous system prosthetic device, implant, or graft, and the thrombosis is considered a sequela (a condition following and resulting from a disease or injury). This applies to situations where the thrombosis is a chronic or late-onset complication, not an immediate post-operative event.

• Requires an additional code to identify the specific nervous system prosthetic device, implant, or graft.
• Distinguish from acute thrombosis; this code is for chronic or late-onset complications.
• Ensure documentation clearly links the thrombosis to the nervous system device as a sequela.
