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

This code signifies a bone break in the right hand that occurred due to an underlying medical condition, rather than trauma, and is currently healing improperly. Malunion indicates that the fracture has healed, but in a misaligned or deformed position. This specific code is used when the patient is seen for follow-up care related to this malunited pathological fracture.

Apply this code for follow-up visits where a patient is being managed for a right hand fracture that healed incorrectly due to a systemic disease (e.g., osteoporosis, bone tumor). Documentation should clearly state "pathological fracture," specify the right hand, confirm malunion, and indicate that the encounter is for subsequent care of the fracture.

• Ensure documentation explicitly states "malunion" and not just "nonunion" (which has a different code).
• Always sequence this code after the underlying disease causing the pathological fracture.
• Verify laterality (right hand) is clearly documented to avoid coding errors.
