Nondisp fx of l ulna styloid pro, 7thR

This code describes a previously treated fracture of the styloid process of the left ulna that was initially an open fracture of a severe type (IIIA, IIIB, or IIIC). The current encounter addresses a complication where the bone has healed in an abnormal alignment, known as malunion, and the fracture itself was nondisplaced.

Use this code for follow-up encounters for a patient with a documented malunion of a left ulnar styloid process fracture that was originally an open fracture type IIIA, IIIB, or IIIC. This would apply when the patient is receiving ongoing care, such as physical therapy, imaging to assess the malunion, or discussion of surgical correction for the malunion.

• Ensure documentation specifies "malunion" and not just "nonunion" or "delayed healing."
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC, and that the current encounter is subsequent.
• Confirm the laterality is left and the specific bone involved is the ulna styloid process.
