Mech compl of internal fixation device of oth bones, sequela

This code signifies a long-term or late-effect complication arising from a mechanical issue with an internal fixation device (e.g., plate, screw, rod) used in a bone other than a joint prosthesis. These complications are not acute and manifest after the initial treatment, often requiring further intervention or ongoing management.

Use this code when documenting a chronic or residual mechanical problem with an internal fixation device in a bone, such as a non-union due to device failure, chronic pain attributed to hardware loosening, or a persistent deformity resulting from device migration. This applies when the original injury or acute complication has resolved, but the device's mechanical issue continues to cause symptoms or problems.

• Always sequence this code after the code for the specific sequela (e.g., non-union, chronic pain, deformity).
• Ensure documentation clearly links the current condition to a past mechanical complication of an internal fixation device.
• Verify the affected bone is not a joint and that the complication is mechanical, not infectious or inflammatory.
