Path fx in neopltc disease, r hand, subs for fx w malunion

This code signifies a pathological fracture of the right hand that occurred due to an underlying neoplastic (cancerous) process. The fracture is currently in a state of malunion, meaning it has healed in an unsatisfactory position, and the patient is presenting for a follow-up encounter related to this specific fracture.

Apply this code when a patient with a known neoplastic disease presents with a malunited pathological fracture of the right hand. Documentation should clearly indicate the fracture's etiology (neoplastic), its location (right hand), the presence of malunion, and that the current visit is a subsequent encounter for this fracture.

• Always sequence the underlying neoplasm code first, followed by this code.
• Distinguish carefully between nonunion (failure to heal) and malunion (healed in poor alignment).
• Ensure documentation specifies "subsequent encounter" for the fracture, not an initial or sequela encounter.
