Nondisplaced fracture of trapezium, left wrist, sequela

This diagnosis code signifies a healed or residual condition resulting from a previous fracture of the trapezium bone in the left wrist, where the bone fragments were not displaced at the time of the original injury. The "sequela" indicates that the patient is experiencing ongoing effects or complications directly attributable to that past fracture, even after the initial healing period.

Use this code when documenting a patient presenting with long-term complications, pain, stiffness, or functional limitations in the left wrist that are directly linked to a previously sustained, nondisplaced trapezium fracture. This code is appropriate for follow-up encounters occurring after the initial healing phase of the fracture, when the primary treatment for the acute injury has concluded.

• Append the 7th character "S" only for encounters addressing the sequelae of the fracture, not for initial treatment or routine follow-up during active healing.
• Always link this diagnosis to a current symptom or condition that is a direct result of the past fracture (e.g., chronic pain, malunion, nonunion, arthritis).
• Ensure documentation clearly supports the connection between the current complaint and the historical nondisplaced left trapezium fracture.
