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

This code signifies a pathological fracture that occurred due to an underlying neoplastic (cancerous) process, where the specific anatomical site of the fracture is not documented. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase of the fracture, and "nonunion" specifies that the fracture has failed to heal completely.

Use this code for follow-up visits where a patient is being managed for a pathological fracture caused by cancer, and the fracture has not united. Documentation should clearly state a pathological fracture, an underlying neoplastic disease, an unspecified fracture site, and the ongoing management of a nonunion.

• Always sequence the underlying neoplasm code first, followed by this code.
• Ensure documentation explicitly states "nonunion" and "pathological fracture due to neoplasm."
• Do not use this code for initial encounters or for fractures that are healing normally.
