Nondisp fx of unsp radial styloid process, init for clos fx

This code signifies a break in the radial styloid process, which is the pointed projection at the end of the radius bone near the wrist, where the bone fragments have not shifted out of alignment. It specifically indicates that the skin over the fracture site remains intact, and this is the first time the patient is being treated for this injury.

Apply this code for patients presenting with a newly diagnosed, non-displaced fracture of the radial styloid process that is closed. This is appropriate for initial evaluations and treatments, such as casting or splinting, following the injury.

• Ensure documentation clearly states "nondisplaced" and "closed fracture" for accurate code assignment.
• The "A" at the end of the code indicates an initial encounter; use subsequent encounter codes for follow-up care.
• If the specific radial styloid (left or right) is documented, use a more specific code from the S52.51- series.
