Nondisp fx of lateral malleolus of l fibula, 7thK

This code signifies a fracture of the outer ankle bone (lateral malleolus) of the left fibula that has not shifted out of alignment. The patient is in a later phase of treatment, and the fracture is failing to heal properly (nonunion) despite the skin remaining intact over the injury site.

Apply this code when documenting ongoing care for a left lateral malleolus fracture where imaging confirms a nonunion, and the fracture was initially treated without surgical exposure. This is appropriate for follow-up visits, cast changes, or evaluations for further intervention due to the lack of healing.

• Ensure documentation clearly states "left" fibula and "lateral malleolus" to differentiate from other ankle fractures.
• Verify that the fracture is explicitly noted as "nondisplaced" and that "nonunion" is documented as the current healing status.
• Confirm this is a "subsequent encounter" and that the fracture is "closed" (no open wound communicating with the fracture site).
