Unsp fx low end l femr, subs for opn fx type I/2 w malunion

This code signifies a fracture of the lower portion of the left thigh bone, where the specific type of fracture is not documented. It indicates that the patient is receiving follow-up care for an initial open fracture (Type I or II) that has healed incorrectly, resulting in malunion.

Apply this code when a patient presents for ongoing treatment of a previously sustained open fracture of the distal left femur, and imaging or clinical assessment confirms malunion. This is appropriate for subsequent visits after the initial fracture care, focusing on the complications of healing.

• Ensure documentation specifies "left femur" and "lower end" for accurate laterality and anatomical site.
• Confirm the original fracture was an "open fracture type I or II" and that "malunion" is explicitly stated or clearly implied by the clinical context.
• This code is for subsequent encounters; do not use for initial treatment of the fracture.
