Path fx in oth disease, l fibula, subs for fx w delay heal

This code signifies a fracture of the left fibula that occurred due to an underlying disease process, not trauma. The patient is in a subsequent phase of care, and the fracture is exhibiting delayed healing, meaning it is taking longer than expected to unite.

Apply this code when documentation indicates a pathological fracture of the left fibula, and the patient is presenting for follow-up care where delayed healing is noted. This code is appropriate after initial treatment has been rendered and the focus is on ongoing management of the fracture's slow progression to union.

• Ensure documentation specifies "pathological fracture" and identifies the underlying disease if known (code the underlying disease first).
• Verify the laterality (left fibula) and the encounter type (subsequent encounter for fracture with delayed healing).
• Do not use this code for nonunion; a different code exists for that specific complication.
