Path fracture in neoplastic disease, left ankle, sequela

This code signifies a pathological fracture of the left ankle that has occurred due to an underlying neoplastic process. It indicates that the fracture is a long-term complication or residual effect of the neoplastic disease, even if the primary malignancy is no longer active.

Apply this code when documentation clearly states a pathological fracture of the left ankle is a sequela of a neoplastic disease. This is appropriate for follow-up encounters where the fracture's long-term effects are being managed, after the acute phase of the fracture and the primary neoplasm treatment. Documentation should specify the laterality (left ankle) and the sequela nature.

• Always sequence this code after the code for the underlying neoplastic disease, even if it's a history code (e.g., Z85.-).
• Ensure documentation explicitly states "sequela" or indicates a long-term effect of the pathological fracture due to neoplasm.
• Do not use this code for acute pathological fractures; instead, use the appropriate M84.572- codes for initial or subsequent encounters.
