Displaced segmental fx shaft of ulna, left arm, init

This code signifies a fracture of the ulna's shaft in the left arm, where the bone is broken into at least three pieces (segmental) and the bone fragments are not properly aligned (displaced). It specifically indicates that this is the first time the patient is being treated for this particular injury.

Use this code for initial encounters when documenting a patient presenting with a newly diagnosed, displaced segmental fracture of the shaft of the left ulna. This applies to emergency department visits, initial orthopedic consultations, or admissions for the immediate management of the fracture.

• Ensure documentation specifies "left arm" and "ulna" to differentiate from radial or bilateral injuries.
• Verify the fracture is explicitly described as "segmental" and "displaced" to support this specific code.
• Confirm this is the initial encounter for treatment; subsequent care will require a different encounter character.
