Oth fx upper end of unsp radius, subs for clos fx w malunion

This code signifies a fracture of the upper portion of the radius bone, excluding specific types like Monteggia or Galeazzi fractures, that has previously been treated but has healed in a misaligned or deformed position. The fracture was initially a closed injury, meaning the skin was not broken.

This code is appropriate for follow-up encounters where a patient presents with ongoing issues related to a previously treated, non-specific closed fracture of the proximal radius that has healed with malunion. This could include assessment of range of motion limitations, pain, or functional impairment due to the malaligned healing.

• Ensure documentation clearly specifies "malunion" and that the initial fracture was closed.
• Verify the fracture location is the "upper end" of the radius and not a more specific type.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
