Path fracture in neoplastic disease, right ankle, sequela

This code signifies a fracture of the right ankle that occurred due to weakening of the bone by a neoplastic (cancerous) process, with the fracture itself being a long-term complication or residual effect. It indicates that the active treatment for the fracture has concluded, and the patient is now experiencing the after-effects.

Use this code when documenting a patient presenting with a pathological fracture of the right ankle that resulted from a neoplastic disease, and the encounter is for the management of a sequela (e.g., malunion, nonunion, chronic pain, or functional limitation) of that healed or healing fracture. Documentation should clearly state the pathological nature of the fracture, its location in the right ankle, the underlying neoplastic disease, and that the current encounter addresses a residual condition.

• Requires a secondary code for the underlying neoplasm (e.g., C79.51 for secondary malignant neoplasm of bone).
• Do not use for active fracture treatment; this "S" code indicates sequela.
• Distinguish from traumatic fractures or pathological fractures due to other diseases (e.g., osteoporosis).
