Greenstick fx shaft of rad, r arm, subs for fx w malunion

This code describes a greenstick fracture affecting the shaft of the right radius that is currently healing with an unsatisfactory alignment of the bone fragments (malunion). A greenstick fracture is an incomplete fracture where one side of the bone is broken and the other is bent.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed greenstick fracture of the right radial shaft that has healed, or is healing, in a misaligned position. This applies when the malunion is a current clinical concern requiring ongoing management or evaluation.

• Ensure documentation clearly specifies "right arm" and "shaft of radius."
• Confirm the encounter is for "malunion" and not delayed union or nonunion, which have different codes.
• Verify this is a "subsequent encounter" for the fracture, indicating ongoing care after the initial treatment.
