Nondisp fx of unsp radial styloid pro, 7thM

This code describes a fracture of the radial styloid process that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates a subsequent encounter for an open fracture (where the skin is broken) of either Type I or Type II, complicated by nonunion, meaning the fracture has failed to heal after the expected time.

This code is used when a patient presents for follow-up care of a previously diagnosed nondisplaced radial styloid fracture that was initially an open fracture (Type I or II) and is now experiencing nonunion. This would apply during clinic visits, physical therapy, or other encounters related to the ongoing management of the unhealed fracture.

• Ensure documentation clearly specifies "nondisplaced" and "radial styloid process."
• Verify the original fracture was an "open fracture type I or II" and that "nonunion" is explicitly documented.
• The 7th character "M" indicates a subsequent encounter for an open fracture with nonunion.
