Path fracture in neoplastic disease, r shoulder, sequela

This code signifies a fracture of the right shoulder bone that occurred due to weakening caused by a neoplastic (cancerous) process, with the fracture's long-term effects or complications being addressed. It indicates that the primary neoplastic disease led to bone fragility, resulting in a pathological fracture, and the current encounter is for a residual condition or late effect of that fracture.

Use this code when a patient presents with a sequela (e.g., chronic pain, nonunion, malunion, functional impairment) directly attributable to a pathological fracture of the right shoulder that was caused by a neoplastic disease. Documentation should clearly state the pathological nature of the fracture, its location, the underlying neoplastic disease, and that the current encounter addresses a long-term consequence.

• Ensure the documentation explicitly links the fracture to a neoplastic disease and specifies "sequela" or a chronic complication.
• Always sequence the code for the underlying neoplastic disease (e.g., C79.51 for secondary malignant neoplasm of bone) before this code, unless the neoplasm is no longer active and only the sequela is being treated.
• Distinguish from acute pathological fractures (M84.511A-D) or subsequent encounters for routine healing (M84.511G-K) which do not represent sequelae.
