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

This code signifies a previously diagnosed, non-specific fracture of the top portion of the left thigh bone (femur) that is now healing incorrectly. The fracture site is not open to the outside environment, and the bone fragments have united in an abnormal position. This malunion can lead to functional impairment and pain.

Apply this code when documenting follow-up care for a patient with a left femoral head fracture that has not healed properly, resulting in malunion. This includes situations where the patient is receiving ongoing treatment, physical therapy, or evaluation for complications related to the malunited fracture. It is used after the initial treatment phase for the acute fracture.

• Ensure "left" femur and "head" of femur are clearly documented.
• Confirm the fracture is closed and healing with malunion, not nonunion or delayed union.
• This code is for a subsequent encounter, meaning the initial treatment for the acute fracture has already occurred.
