Oth fracture of shaft of unsp fibula, init for clos fx

This code signifies a break in the shaft of the fibula, the smaller of the two lower leg bones, where the specific location on the shaft is not detailed. It indicates that the skin over the fracture site remains intact (closed fracture) and that this is the initial treatment encounter for the injury.

Apply this code for a patient presenting with a newly diagnosed, non-displaced or displaced closed fracture of the fibular shaft when the precise segment (e.g., proximal, distal) is not documented. This is appropriate for the initial visit where definitive treatment, such as casting or splinting, is initiated.

• Ensure documentation specifies "closed" and "shaft" of the fibula; if open, a different code is required.
• This "unspecified" code should be used only when more specific anatomical detail (e.g., proximal, distal) is not available in the medical record.
• Always append a seventh character for subsequent encounters (D, G, K, P, S) as appropriate for the phase of care.
