Thrombosis due to internal orth prosth dev/grft, sequela

This code signifies a blood clot that has formed as a long-term complication of an internal orthopedic device, such as a joint replacement, internal fixation hardware, or a bone graft. It indicates that the thrombosis is a residual effect or late complication of the presence of the prosthetic material.

Use this code when documenting a patient presenting with a thrombosis that is directly attributed to a previously implanted orthopedic device, and the thrombosis is considered a sequela (a condition following as a consequence of a previous disease or injury). This applies to situations where the acute phase of the initial complication has passed, but the thrombosis persists or has developed later due to the device.

• Requires a seventh character 'S' to indicate sequela, meaning the complication is a late effect.
• Ensure documentation clearly links the thrombosis to the orthopedic device and specifies it as a chronic or late complication.
• Do not use for acute thrombosis directly following the implantation procedure; other codes exist for acute complications.
