Path fracture in neoplastic disease, right ulna, sequela

This code signifies a fracture of the right ulna that occurred due to the weakening of the bone by a neoplastic (cancerous) process, with the fracture itself being a long-term consequence or late effect of the original injury. It indicates that the acute phase of the fracture has passed, and the patient is now experiencing residual effects.

Apply this code when documenting the follow-up care or ongoing management of a patient whose right ulnar fracture was caused by cancer, and the fracture is no longer acute. Documentation should clearly state "sequela," "late effect," or indicate that the fracture is old, healed, or in a chronic phase, and directly link it to a neoplastic disease.

• Always sequence a code for the underlying neoplastic disease first, followed by this sequela code.
• Do not use for acute pathological fractures; those require codes from the M84.531A-M84.531P range.
• Ensure documentation specifies "right ulna" and "sequela" to support this specific code.
