Nondisp fx of lateral malleolus of unsp fibula, 7thB

This code describes a break in the outer ankle bone (lateral malleolus) of an unknown fibula that has not shifted out of place. The fracture is an open type I or II, meaning there is a wound communicating with the fracture site, but the bone fragments are not severely displaced or comminuted. This code is used for the initial treatment of such an injury.

Use this code when documenting the initial encounter for a patient presenting with an open, non-displaced fracture of the lateral malleolus, and the specific side (left or right) of the fibula is not documented. This applies to injuries where the skin is broken but the wound is relatively clean and small, or larger but without significant soft tissue damage.

• Ensure documentation clearly states "unspecified fibula" if the laterality is not specified.
• Verify the fracture is explicitly described as "nondisplaced" and "open type I or II."
• Confirm this is the patient's initial visit for this specific injury.
