Nondisp trimalleol fx unsp low leg, 7thC

This code signifies a fracture involving all three malleoli (medial, lateral, and posterior) of an unspecified lower leg, where the bone fragments remain in their anatomical position. It specifically applies when the fracture is an open fracture of severe type (IIIA, IIIB, or IIIC), indicating significant soft tissue damage and potential contamination. This code is used for the initial treatment of such an injury.

Use this code for a patient presenting for the first time with a trimalleolar fracture of an unknown lower leg, confirmed to be nondisplaced. The fracture must be classified as an open fracture type IIIA, IIIB, or IIIC, typically requiring extensive surgical debridement and management due to the severity of the soft tissue injury. This code is appropriate for the acute phase of care.

• Ensure documentation clearly specifies "nondisplaced" and "trimalleolar fracture."
• Verify the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated in the medical record.
• Confirm this is the patient's initial encounter for this specific injury.
