Unsp fx upper end of r radius, subs for clos fx w malunion

This code indicates a previously sustained, unspecified fracture of the upper part of the right radius that is now healing improperly, specifically with malunion. The fracture was initially closed, meaning the skin was not broken at the time of injury.

Apply this code when a patient presents for follow-up care of a right radial head or neck fracture that is healing in an unsatisfactory alignment. This would be used after the initial treatment phase, during the period of ongoing management for the malunion.

• Requires a seventh character of 'P' for subsequent encounter with malunion.
• Ensure documentation clearly specifies "right" radius and "upper end" (e.g., radial head, neck).
• Do not use for nonunion; a different seventh character would be required for that complication.
