Dislocation of distal end of right ulna, initial encounter

This code signifies a complete displacement of the far end of the right ulna bone from its normal articulation, typically at the wrist joint. This injury involves the disruption of the joint capsule and ligaments that normally stabilize the distal ulna.

This code is appropriate for the initial treatment of a patient presenting with a newly diagnosed dislocation of the distal right ulna. This includes emergency department visits, initial orthopedic consultations, and any other first encounter for this specific injury.

• Ensure documentation clearly specifies the right side and that it is the initial encounter for this injury.
• Distinguish from subluxation or fracture-dislocation, which would require different codes.
• Confirm the dislocation involves the distal end of the ulna, not other carpal or radial dislocations.
