Traumatic rupture of collateral ligament of left wrist, init

This code signifies an acute, forceful tearing or complete disruption of one or more collateral ligaments supporting the left wrist joint. This injury typically results from a sudden, excessive force or hyperextension/hyperflexion of the wrist, leading to instability and pain.

Apply this code for initial encounters with patients presenting with a newly diagnosed, acute traumatic rupture of a collateral ligament in their left wrist. This includes cases seen in emergency departments, urgent care, or a physician's office shortly after the injury occurred.

• Ensure documentation clearly specifies "rupture" and not just a sprain or tear, as these are distinct diagnoses.
• Confirm the laterality is "left wrist" and the encounter is the "initial" one for this specific injury.
• Look for details on the mechanism of injury and physical exam findings consistent with ligamentous instability.
