Breakdown (mechanical) of int fix of bone of r low leg, subs

This code signifies a mechanical failure of an internal fixation device, such as a plate, screw, or rod, that was surgically implanted to stabilize a fracture in the right lower leg. The device itself has broken, bent, or otherwise malfunctioned, leading to a loss of its intended structural integrity. This is not an infection or a displacement, but a material failure of the implant.

Apply this code when a patient presents for follow-up care or treatment related to a previously implanted internal fixation device in their right lower leg, and imaging or clinical assessment confirms a mechanical breakdown of that device. This typically occurs after the initial treatment phase, during a subsequent encounter for management of this complication.

• Ensure documentation clearly specifies "mechanical breakdown" or "failure" of the device, not just "loosening" or "displacement" without mechanical failure.
• Verify the laterality is explicitly documented as the "right lower leg."
• Confirm this is a "subsequent encounter" for the complication, not the initial treatment of the original fracture or the initial diagnosis of the device breakdown.
