Path fx in neopltc dis, unsp femur, subs for fx w nonunion

This code signifies a fracture of an unspecified femur that occurred due to an underlying neoplastic (cancerous) process, and the patient is now presenting for follow-up care because the fracture has not healed properly (nonunion). It indicates a complication of the initial pathological fracture, specifically a failure of bone repair.

Use this code for a patient with a documented pathological fracture of the femur (site not specified) due to cancer, who is returning for treatment or evaluation of a nonunion. Documentation should clearly state the pathological nature of the fracture, the anatomical site (femur), and the nonunion status during a subsequent encounter.

• Ensure documentation specifies "pathological fracture" and the underlying neoplastic disease.
• Distinguish between initial (A), subsequent (D, G, K, P, S), and sequela (S) encounters based on the patient's current phase of care. "K" indicates subsequent encounter for fracture with nonunion.
• Always code the underlying neoplasm first, followed by this code for the pathological fracture.
