Pathological fracture in other disease, unsp ankle, sequela

This code signifies a pathological fracture of an unspecified ankle that occurred due to an underlying disease process, not from trauma. It indicates that the fracture itself is a late effect or complication of the initial pathological fracture event. The "unspecified ankle" component means the laterality (left or right) is not documented.

Apply this code when documentation clearly states a pathological fracture of the ankle (laterality unknown) as a sequela, meaning the patient is receiving care for the long-term effects or complications of the original fracture. This code is appropriate for follow-up visits after the initial healing phase of a pathological fracture, or when addressing residual issues directly attributable to it. The medical record must specify "pathological fracture" and indicate the "sequela" nature of the encounter.

• Always seek documentation for laterality (left/right) of the ankle; if specified, a more precise code should be used.
• This "S" encounter code is used for complications or conditions arising as a direct result of the initial pathological fracture, after the acute phase of healing has passed.
• Code the underlying disease causing the pathological fracture first, followed by this sequela code.
