Displaced fracture of left ulna styloid process, sequela

This code signifies a past injury involving a displaced fracture of the styloid process of the left ulna, where the fracture fragments were not in their normal anatomical alignment. The "sequela" indicates that this code is used to report conditions or complications that are the late effects of the original fracture, even after the acute phase of healing has passed.

This code is appropriate when a patient presents with a current condition or symptom that is a direct result of a previously sustained, displaced fracture of the left ulnar styloid. Examples include chronic pain, nonunion, malunion, or functional limitations directly attributable to the old fracture. It should not be used for the initial treatment of the acute fracture.

• Always sequence this code after the code describing the specific sequela (e.g., M25.522 for chronic pain in left elbow).
• Ensure documentation clearly links the current condition to the prior displaced left ulnar styloid fracture.
• Verify that the fracture was indeed displaced and located on the left ulna's styloid process.
