Nondisp fx of lateral malleolus of unsp fibula, 7thP

This code signifies a previously sustained fracture of the outer ankle bone (lateral malleolus) that was not displaced at the time of injury. The fracture has healed, but the bone fragments have joined in an abnormal alignment, resulting in a malunion. This code is used during a follow-up visit after the initial treatment.

This code is appropriate for encounters where a patient is being evaluated or treated for complications arising from a malunited, nondisplaced lateral malleolus fracture. This includes scenarios such as pain, functional limitations, or deformity due to the malunion, after the initial fracture care has concluded.

• Ensure documentation clearly states "malunion" and specifies the "lateral malleolus" and "nondisplaced" nature of the original fracture.
• Verify this is a "subsequent encounter" for the fracture, not the initial treatment or routine follow-up for a healing fracture without complications.
• Confirm the laterality (left, right, or unspecified) of the fibula is accurately reflected in the full code.
