Breakdown (mechanical) of int fix of left femur, sequela

This code describes a long-term complication where an internal fixation device, such as a plate, screw, or rod, implanted in the left femur has mechanically failed or broken down. This breakdown can lead to instability, pain, or non-union of the fracture, requiring further medical intervention. The 'S' in the seventh character indicates that this is a sequela, meaning it's a late effect or complication of an earlier injury or surgery.

Use this code when documenting a patient presenting with issues directly attributable to the mechanical failure of a left femoral internal fixation device, and the initial injury or surgery has already been treated. This applies to situations where the patient is experiencing ongoing problems due to the device's breakdown, even if the original fracture has healed. This code is appropriate for follow-up encounters for complications arising from the device failure.

• Always use this code as a secondary diagnosis, following a code for the specific complication (e.g., nonunion, malunion, pain).
• Ensure documentation clearly specifies "left femur" and "mechanical breakdown" of the internal fixation device.
• The 'S' seventh character indicates a sequela, meaning this code is for complications arising after the acute phase of the initial injury or surgery.
