Displ seg fx shaft of ulna, r arm, init for opn fx type I/2

This code signifies a fracture of the ulna's shaft in the right arm, where the bone is broken into at least three pieces (segmental) and the fragments are not properly aligned (displaced). The injury involves a break in the skin (open fracture), classified as either Type I (minimal skin damage) or Type II (moderate skin damage with some muscle contusion).

This code is appropriate for initial treatment encounters of patients presenting with an open, displaced, segmental fracture of the right ulnar shaft. This would include situations like emergency room visits, initial orthopedic consultations, or hospital admissions for the immediate management of such an injury.

• Confirm the fracture is specifically of the ulnar shaft and not the olecranon or styloid process.
• Verify documentation explicitly states "displaced" and "segmental" for accurate coding.
• Ensure the open fracture is classified as Type I or II; different types will require a different 7th character.
