Displaced transcondylar fracture of left humerus, sequela

This code signifies a long-term complication or residual effect stemming from a previously sustained, off-set fracture through the condyles of the left upper arm bone. These sequelae can include chronic pain, limited range of motion, nonunion, malunion, or nerve damage that persists after the initial healing phase of the fracture. It indicates that the patient is still experiencing issues directly attributable to the original injury.

Apply this code when documenting a patient presenting with ongoing problems or conditions that are a direct consequence of a past displaced transcondylar fracture of the left humerus. This is appropriate for follow-up visits addressing chronic pain, functional limitations, or other persistent complications related to the original injury, long after the acute phase has passed. Do not use for the initial treatment of the fracture itself.

• Always use this "S" seventh character for sequela, indicating a late effect of the injury.
• Code any specific sequela (e.g., M25.522 for chronic pain, M21.922 for unspecified deformity) in addition to this code.
• Ensure documentation clearly links the current condition to the previous transcondylar fracture of the left humerus.
