Path fx in neopltc disease, l femur, subs for fx w nonunion

This code signifies a pathological fracture of the left femur that has occurred due to an underlying neoplastic disease. It specifically indicates that the patient is in a subsequent phase of care for this fracture, and a nonunion of the fracture fragments has been identified.

Use this code when a patient with a known neoplastic disease presents for follow-up treatment of a left femoral fracture, and imaging or clinical assessment confirms that the fracture has failed to heal (nonunion). Documentation should clearly state the presence of a pathological fracture, its location in the left femur, the underlying neoplastic etiology, and the nonunion status during a subsequent encounter.

• Ensure documentation specifies "nonunion" for the subsequent encounter, not just delayed healing.
• Always code the underlying neoplastic disease first, followed by this code.
• Distinguish between initial, subsequent, and sequela encounters based on the patient's phase of care.
