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

This code indicates a fracture of the shaft of the right radius that was not specified further as to type (e.g., transverse, oblique, spiral). The patient is in a subsequent phase of care for this injury, and the fracture, though initially closed, has healed in an unsatisfactory position (malunion).

Use this code when a patient presents for follow-up care, such as physical therapy, cast changes, or evaluation of healing, for an unspecified closed fracture of the right radial shaft that has resulted in malunion. This code is appropriate when the initial treatment has concluded, but ongoing management of the malunion is required.

• Ensure documentation clearly states "subsequent encounter" and "malunion" for a closed fracture.
• Verify the fracture location is specifically the "shaft" of the right radius and that the type of fracture is unspecified.
• Do not use for initial treatment or for nonunion; specific codes exist for those scenarios.
