Path fx in neopltc disease, r fibula, subs for fx w nonunion

This code signifies a fracture of the right fibula that occurred due to an underlying neoplastic (cancerous) process, which has failed to heal properly (nonunion). The patient is in a subsequent phase of treatment for this specific fracture.

Use this code when a patient with a known neoplastic disease presents for follow-up care or ongoing treatment of a right fibula fracture that is not uniting. Documentation should clearly state the fracture is pathological, located in the right fibula, and that nonunion is present, along with an indication of a subsequent encounter.

• Always sequence the underlying neoplasm code first, followed by this code.
• Ensure documentation specifies "nonunion" for the fracture; otherwise, a different subsequent encounter code for pathological fracture may be more appropriate.
• Verify the laterality (right fibula) and the encounter type (subsequent) are explicitly documented.
