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

This code signifies a fracture of the hip that occurred due to a pre-existing neoplastic (cancerous) condition, where the fracture has failed to heal properly (nonunion). This specific code is used for a patient who is receiving follow-up care for this non-healing pathological fracture.

Apply this code when documentation indicates a patient is being treated for a hip fracture caused by cancer, and the fracture has not united, during a subsequent encounter for care. This includes situations where the patient is undergoing ongoing treatment for the nonunion, such as further surgical intervention or conservative management.

• Always sequence the underlying neoplasm code first, followed by this code.
• Ensure documentation clearly states "nonunion" and specifies the hip as the fracture site.
• Distinguish from initial encounters for the fracture or encounters for routine healing.
