Unsp fx shaft of r rad, subs for opn fx type I/2 w malunion

This code signifies a follow-up encounter for a right radius shaft fracture that was initially an open fracture (Type I or II) and has subsequently healed in a misaligned position. The specific nature of the fracture to the shaft of the radius is not documented.

Apply this code when a patient presents for ongoing care of a previously sustained open fracture of the right radial shaft, and imaging or clinical assessment confirms malunion. This is appropriate for subsequent visits after the initial treatment of the open fracture, where the focus is on managing the malaligned healing.

• Ensure documentation specifies "subsequent encounter" and confirms malunion of an open fracture.
• Verify the fracture location is the shaft of the right radius.
• Do not use for initial treatment or for nonunion; a different code would be required.
