Nondisp fx of l ulna styloid pro, 7thM

This code describes a fracture of the styloid process of the left ulna that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates a subsequent encounter for an open fracture of Type I or II, where the bone has failed to heal properly (nonunion).

This code is appropriate when a patient presents for follow-up care of a previously diagnosed open fracture (Type I or II) of the left ulnar styloid, and imaging or clinical assessment confirms that the fracture has not united. This would typically be used after initial treatment, during ongoing management of the nonunion.

• Confirm the fracture is specifically of the ulnar styloid and on the left side.
• Verify documentation clearly states "nondisplaced" and "nonunion."
• Ensure the original fracture was an "open fracture type I or II" and this is a subsequent encounter.
