Oth fracture of left femur, subs for clos fx w nonunion

This code signifies a fracture in the left femur, excluding the shaft, neck, or trochanteric regions, that has failed to heal properly after an initial treatment. The fracture is currently closed, meaning the skin remains intact over the fracture site, and the patient is receiving ongoing care for this nonunion.

Use this code for patients presenting for follow-up care, such as cast changes, physical therapy, or surgical planning, for a previously diagnosed and treated closed fracture of the left femur (excluding specific anatomical sites) that has not united. This applies when the physician explicitly documents nonunion and the encounter is not for the initial treatment of the fracture.

• Ensure documentation clearly states "nonunion" and specifies the left femur, excluding neck, shaft, or trochanteric fractures.
• This code is for subsequent encounters only; do not use for the initial treatment of the fracture.
• Verify the fracture is documented as "closed" to avoid using codes for open fractures.
