Path fracture in neoplastic disease, unsp ankle, sequela

This code signifies a pathological fracture of an unspecified ankle that occurred due to an underlying neoplastic disease. It indicates that the fracture itself is no longer acute but rather a long-term consequence or late effect of the original injury.

Apply this code when documentation clearly states a pathological fracture of the ankle (without specifying right or left) caused by cancer, and the patient is presenting for treatment of the residual effects or complications of that fracture, not the initial acute injury. This code is appropriate for follow-up care, rehabilitation, or management of nonunion/malunion related to the previous pathological fracture.

• Always sequence this S-code after the code for the underlying neoplastic disease.
• Ensure documentation specifies "sequela" or "late effect" of the fracture, not an acute event.
• Verify laterality (right/left) is truly unspecified; if known, a more specific code should be used.
