Nondisp seg fx shaft of humer, r arm, subs for fx w malunion

This code signifies a follow-up encounter for a right humerus shaft fracture that involves a segment of the bone and is not displaced. Importantly, the fracture has healed in an unsatisfactory position, resulting in malunion. This indicates a complication of the healing process.

Apply this code when a patient presents for ongoing management or evaluation of a previously sustained right humeral shaft fracture that has healed with malunion. This would include scenarios such as assessing functional limitations, planning corrective surgery, or monitoring the long-term effects of the malunion. It is used after the initial treatment of the fracture.

• Ensure documentation clearly states "malunion" as a complication of the fracture healing.
• Verify the fracture location is specifically the shaft of the humerus and on the right side.
• Confirm this is a "subsequent encounter" and not the initial treatment phase.
