Displaced segmental fx shaft of ulna, right arm, sequela

This code signifies a past injury to the right ulna, specifically a segmental fracture of the shaft that was displaced. The "sequela" designation indicates that the patient is experiencing a late effect or complication directly resulting from this previous fracture, even after the initial healing period. This could include chronic pain, nonunion, malunion, or functional impairment.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct consequence of a previously sustained, displaced segmental fracture of the right ulnar shaft. This is appropriate for follow-up visits addressing long-term complications, rehabilitation, or surgical interventions for these late effects. Do not use for the initial treatment of the acute fracture.

• Always assign an additional code to specify the nature of the sequela (e.g., M84.2x for nonunion, M96.0 for pseudarthrosis).
• Ensure documentation clearly links the current condition to the historical right ulnar shaft fracture.
• This code is for the right arm only; verify laterality carefully.
