Pathological fracture, unspecified tibia and fibula, sequela

This code signifies a pathological fracture of an unspecified tibia and fibula that is now a sequela. A pathological fracture occurs due to a pre-existing disease weakening the bone, rather than from trauma. The "sequela" designation indicates that this code is used for conditions that are the late effects or residual complications of the original fracture.

Use this code when documenting a long-term complication or residual effect directly attributable to a pathological fracture of the tibia and fibula, where the specific bone (tibia or fibula) is not documented. This code is appropriate when the acute phase of the fracture has passed, and the patient is being treated for a chronic issue stemming from the original pathological break. Documentation should clearly state "sequela" or "late effect" of a pathological pathological fracture.

• Ensure documentation explicitly states "pathological fracture" and "sequela" or "late effect."
• Do not use this code for acute pathological fractures; instead, use the appropriate M84.4- code for the active phase.
• Always sequence this code after the code for the underlying condition that caused the pathological fracture, if still relevant and being treated.
