Path fracture in neoplastic disease, left hand, sequela

This code signifies a pathological fracture of the left hand that occurred due to an underlying neoplastic disease, and the patient is now experiencing a long-term complication or late effect of that fracture. This indicates the fracture has healed, but residual issues related to the fracture or its treatment persist.

Use this code when documentation clearly states a patient is experiencing a sequela (e.g., chronic pain, nonunion, malunion, limited range of motion, deformity) of a pathological fracture in the left hand, and the fracture was caused by a neoplasm. The original fracture must have occurred in the past, and the current encounter addresses the lingering effects.

• Requires a seventh character 'S' for sequela, indicating the current encounter is for the late effects of the fracture.
• Always sequence this code after the code for the underlying neoplastic disease (e.g., C79.51 for secondary malignant neoplasm of bone).
• Do not use this code for an active, acute pathological fracture; instead, use the appropriate M84.542_ code with an A, D, or G seventh character.
