Displaced oblique fracture of shaft of left ulna, sequela

This code signifies a past oblique fracture of the shaft of the left ulna that was displaced, and the patient is now experiencing a complication or residual effect directly related to that previous injury. This could include chronic pain, malunion, nonunion, nerve damage, or restricted range of motion stemming from the original fracture.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct consequence of a previously sustained, displaced oblique fracture of the left ulnar shaft. This is appropriate for follow-up encounters addressing long-term issues rather than the initial treatment of the acute fracture.

• Requires an additional code to specify the nature of the sequela (e.g., M84.2x for nonunion, M25.522 for chronic pain in left elbow).
• Only use for conditions that are a direct, late effect of the original fracture, not for unrelated new injuries.
• Ensure documentation clearly links the current condition to the past displaced oblique fracture of the left ulnar shaft.
