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

This code indicates 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 patient's left thigh bone. This breakdown is occurring during the healing phase, after the initial treatment of the fracture.

Use this code for follow-up encounters where a patient presents with complications directly related to the mechanical failure of a left femoral internal fixation device. This includes situations where the device has bent, broken, loosened, or migrated, requiring further medical attention or intervention.

• Ensure documentation clearly specifies the left femur and that the issue is a mechanical breakdown of the device, not an infection or other complication.
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always code the underlying reason for the original fixation (e.g., fracture of left femur) as a secondary diagnosis if still relevant.
