Unsp fracture of left femur, subs for clos fx w malunion

This code signifies a fracture of the left femur where the specific type of fracture (e.g., transverse, spiral) is not documented, and the patient is receiving ongoing care for a closed fracture that has healed in an imperfect or misaligned position. This indicates a complication of the initial fracture healing process.

Use this code for follow-up visits, rehabilitation, or further surgical intervention related to a previously sustained, unspecified closed left femoral fracture that has resulted in malunion. This applies when the patient is no longer in the initial healing phase but is being treated for the consequences of the improper bone alignment.

• Ensure documentation clearly states "malunion" and specifies the left femur.
• This code is for subsequent encounters; an initial encounter for the fracture would use an initial encounter code.
• Verify that the fracture was closed; open fractures have distinct coding pathways.
