Nondisp commnt fx shaft of ulna, r arm, 7thK

This code describes a fracture of the shaft of the right ulna that has broken into multiple pieces (comminuted) but where the bone fragments are still in their normal anatomical alignment (nondisplaced). The "K" seventh character indicates that the patient is receiving follow-up care for this closed fracture, and a complication of nonunion has been identified, meaning the bone is failing to heal properly.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed nondisplaced comminuted fracture of the right ulnar shaft is being treated for the ongoing management of the fracture, specifically when nonunion is present. This would include visits for cast changes, follow-up imaging to assess healing, or discussions regarding surgical intervention for the nonunion.

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the ulnar shaft fracture.
• The "K" seventh character is crucial and indicates a subsequent encounter for a closed fracture with nonunion.
• Confirm the laterality is "right arm" as specified by the code.
