Pathological fracture in other disease, unsp foot, sequela

This code signifies a pathological fracture of an unspecified foot that occurred due to an underlying disease process, and the patient is now experiencing a late effect or complication of that fracture. The fracture itself is no longer acute, and the patient is receiving care for residual problems directly related to the previous pathological break.

Apply this code when documentation clearly indicates a healed or healing pathological fracture of the foot, where the patient is presenting for treatment of a sequela (e.g., malunion, nonunion, chronic pain, deformity) directly attributable to that fracture. The original pathological fracture must have been caused by a systemic disease rather than trauma.

• Ensure documentation specifies the "sequela" nature of the encounter, indicating the fracture is not acute.
• Always code the underlying disease responsible for the pathological fracture first, if still active and relevant to the sequela.
• Do not use this code for acute pathological fractures; instead, select an acute pathological fracture code with the appropriate initial, subsequent, or routine encounter seventh character.
