Nondisp fx of lateral malleolus of unsp fibula, 7thH

This code describes a fracture of the outer ankle bone (lateral malleolus) that has not shifted out of alignment. The fracture was initially an open fracture (skin broken) of type I or II, and the patient is now presenting for follow-up care due to delayed healing of this specific injury.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed nondisplaced open type I or II lateral malleolus fracture is experiencing delayed healing. This would include follow-up appointments for cast changes, wound care, or imaging to assess the healing progress when the bone union is not occurring at the expected rate.

• Ensure documentation specifies "nondisplaced" and "lateral malleolus" for laterality.
• Verify the initial fracture was an "open fracture type I or II" and that "delayed healing" is explicitly documented.
• Confirm this is a "subsequent encounter" and not the initial treatment.
