Tidal wave due to earthquake or volcanic eruption, init

This code signifies an injury or adverse health effect sustained by an individual as a direct result of a tidal wave (tsunami) that was generated by either an earthquake or a volcanic eruption. It covers the initial assessment and treatment of the patient for these specific circumstances.

Apply this code when documenting the first encounter for a patient who has experienced trauma, drowning, or other health issues directly attributable to a tsunami caused by seismic or volcanic activity. This includes immediate post-event care in emergency departments, field hospitals, or initial inpatient admissions.

• Ensure the documentation clearly links the patient's condition to a tsunami caused by an earthquake or volcanic eruption.
• This "initial encounter" designation is used as long as the patient is receiving active treatment for the acute injury.
• Always code additional specific injuries (e.g., fractures, lacerations, near-drowning) in conjunction with this external cause code.
