Path fracture in oth disease, unsp tibia and fibula, sequela

This code signifies a pathological fracture of an unspecified tibia and fibula that occurred due to an underlying disease process, and the patient is now experiencing a long-term complication or late effect from that fracture. This indicates that the acute phase of the fracture has passed, and the current encounter addresses a residual problem.

Apply this code when documentation clearly indicates a healed or resolving pathological fracture of the tibia and fibula, and the patient is presenting for treatment of a sequela directly related to that past fracture. This is appropriate for follow-up care of chronic pain, nonunion, malunion, or functional impairment stemming from the original pathological fracture.

• Always sequence this sequela code after the code for the specific underlying disease that caused the pathological fracture.
• Ensure documentation specifies "pathological fracture" and the specific bone(s) involved (tibia and fibula) to differentiate from traumatic fractures.
• Do not use for acute pathological fractures; those require codes from the M84.4- or M84.5- series.
