Fracture of lateral malleolus, closed

This code signifies a break in the fibula bone at its distal end, specifically the lateral malleolus, without an open wound communicating with the fracture site. It represents a common ankle injury, often resulting from twisting or inversion forces.

Assign this code for documented closed fractures of the lateral malleolus, typically confirmed by X-ray. It is appropriate for initial encounters for acute injuries. Documentation should clearly state "closed fracture" and specify the lateral malleolus.

• Ensure documentation explicitly states "closed" to differentiate from open fractures.
• Do not use for stress fractures or pathological fractures; separate codes exist for those conditions.
• Consider additional codes for associated injuries, such as ligamentous tears (e.g., sprains), if documented.
