Displ commnt fx shaft of rad, r arm, 7thM

This code describes a complex fracture of the right radius, specifically a displaced comminuted break in the shaft. It indicates that the initial injury was an open fracture (Type I or II) and that the bone has failed to heal properly, resulting in a nonunion. This code is used for follow-up care after the initial treatment.

This code is appropriate for subsequent encounters when a patient with a previously treated open comminuted shaft fracture of the right radius (Type I or II) is being managed for nonunion. This includes visits for ongoing evaluation, planning for further surgical intervention for the nonunion, or monitoring of conservative management for the nonunion.

• Ensure documentation clearly specifies "nonunion" as the reason for the subsequent encounter.
• Verify the fracture is of the radial shaft and not the distal or proximal end.
• Confirm the initial injury was an open fracture, Type I or II, as this impacts the specific S52.351 subcategory.
