Nondisp fx of head of left rad, subs for clos fx w malunion

This code describes a previously sustained, non-displaced fracture of the radial head in the left arm that is now healing improperly, specifically with malunion. The fracture itself is closed, meaning the skin was not broken at the time of injury, and the patient is in a subsequent phase of care for this condition.

Apply this code when a patient presents for follow-up care of a left radial head fracture that was initially non-displaced, but imaging or clinical assessment now confirms malunion. This is appropriate for office visits, physical therapy, or other subsequent encounters where the focus is on managing the healing process with this complication.

• Ensure documentation clearly specifies "left radius" and "head" to differentiate from other forearm fractures.
• Confirm "malunion" is explicitly documented; do not assume based on delayed healing alone.
• Verify the encounter is "subsequent" and not the initial treatment for the fracture.
