Nondisp fx of l ulna styloid pro, 7thN

This code describes a fracture of the styloid process of the left ulna that has not shifted from its normal anatomical position. This particular encounter is for ongoing treatment of a severe open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) where the bone fragments have failed to heal properly, resulting in a nonunion.

Use this code for follow-up encounters where a patient is being treated for a nonunion of a previously sustained nondisplaced open fracture of the left ulnar styloid. This applies when the original open fracture was classified as Gustilo-Anderson type IIIA, IIIB, or IIIC. This code is appropriate for subsequent visits related to managing the nonunion, such as for cast changes, wound care, or evaluation for surgical intervention.

• Ensure documentation clearly specifies "nondisplaced" and identifies the "left ulna styloid process."
• Verify the original open fracture was classified as Gustilo-Anderson type IIIA, IIIB, or IIIC and that nonunion is explicitly documented.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
