Unsp trochan fx left femur, subs for clos fx w malunion

This code signifies a left femoral trochanteric fracture that was initially closed but is now being managed during a subsequent encounter. The key clinical finding for this code is the presence of malunion, indicating the fracture has healed in an anatomically incorrect position. This malunion may lead to ongoing pain, functional impairment, or the need for further intervention.

Use this code when documenting follow-up care for a patient with a previously treated closed trochanteric fracture of the left femur. The encounter must specifically address the identified malunion, which could be confirmed by imaging or clinical assessment. This code is appropriate for ongoing management, evaluation for corrective surgery, or monitoring of the malunion.

• Ensure documentation clearly specifies "left" femur and "trochanteric" location.
• Verify the encounter is "subsequent" and that "malunion" is explicitly stated or clearly implied by the clinical context.
• Pair with an external cause code if the initial injury mechanism is relevant to the current encounter.
