Complete oblique atypical femoral fracture, left leg, 7thP

This code signifies a complete fracture of the femur, specifically an oblique atypical type, located in the left leg. The "P" seventh character indicates that this is a subsequent encounter for a fracture that is healing with a malunion, meaning the bone fragments have united in a deformed or misaligned position.

Use this code when a patient presents for follow-up care of a previously diagnosed oblique atypical femoral fracture of the left leg that has healed incorrectly. Documentation should clearly state "malunion" and specify the left femur as the affected site. This code is appropriate for encounters related to managing the malunion, such as planning for corrective surgery or monitoring its impact.

• Ensure documentation explicitly states "malunion" and not just "nonunion" (which uses a different seventh character).
• Verify the laterality (left leg) is clearly documented; right leg or unspecified would require a different code.
• Confirm the fracture type is "atypical" and "oblique" as other femoral fracture types have distinct codes.
