Displ artic fx head of l femur, subs for clos fx w malunion

This code describes a fracture involving the joint surface of the head of the left femur that has shifted from its normal alignment. The patient is in a subsequent phase of care, and the fracture is closed, meaning the skin is intact, but it has healed in an unsatisfactory position, resulting in malunion.

Use this code for follow-up encounters where a patient is being treated for complications arising from a previously sustained, displaced articular fracture of the left femoral head, specifically when imaging confirms malunion. This applies when the fracture itself is no longer acute but the healing process has resulted in an anatomical deformity.

• Ensure documentation clearly specifies "left" femur and "articular" involvement of the femoral head.
• Confirm the encounter is for a "subsequent" phase of care and that "malunion" is explicitly documented.
• Verify the fracture is "closed"; if open, a different code would be required.
