Oth fx of low end r rad, subs for opn fx type I/2 w malunion

This code signifies a fracture of the lower part of the right radius that is not further specified as comminuted, Salter-Harris, or Torus. It specifically applies when the initial injury was an open fracture of type I or II, and the bone has healed in an abnormal position (malunion). This indicates a complication during the healing process of a previously open distal radial fracture.

This code is appropriate for documenting follow-up care for a patient who sustained an open fracture (type I or II) of the distal right radius, and subsequent imaging or clinical assessment reveals that the bone has healed with an unacceptable alignment. It would be used for encounters related to managing this malunion, such as planning for corrective osteotomy or assessing functional limitations.

• Ensure documentation clearly specifies "right radius" and "lower end" to differentiate from other radial fractures.
• Confirm the original fracture was an "open fracture type I or II" and that "malunion" is explicitly documented.
• Do not use for initial encounters or for nonunion; a separate code exists for those scenarios.
