Path fracture in oth disease, l hand, subs for fx w malunion

This code indicates a fracture of the left hand that occurred due to an underlying disease process, not from trauma. The fracture is currently in a healing phase, but the bone fragments have united in a deformed or misaligned position. This malunion may impair hand function and require further intervention.

Apply this code when documentation specifies a pathological fracture of the left hand that has healed incorrectly. This code is appropriate for follow-up encounters where the malunion is being addressed or monitored. Physician notes should clearly state "pathological fracture," "left hand," "malunion," and indicate a subsequent encounter.

• Ensure the documentation specifies "pathological fracture" and not a traumatic fracture.
• Verify the laterality (left hand) and the encounter type (subsequent encounter for fracture with malunion).
• Always code the underlying disease responsible for the pathological fracture first, if known and still active.
