Unsp fx shaft of r radius, subs for clos fx w nonunion

This code signifies a follow-up encounter for a right radial shaft fracture that was initially treated non-surgically (closed reduction) but has failed to heal properly (nonunion). The specific location on the radius shaft is not further defined.

Apply this code when a patient presents for ongoing management of a previously treated closed fracture of the right radial shaft, and imaging or clinical assessment confirms a nonunion. This is appropriate for subsequent visits after the initial treatment and diagnosis of nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right radius shaft.
• Verify the fracture was initially treated as a closed fracture.
• This is a 7th character 'K' code, indicating a subsequent encounter for a closed fracture with nonunion.
