Other cataclysmic storms, sequela

This code signifies a long-term health condition or complication resulting from exposure to a cataclysmic storm other than a hurricane, tornado, or flood. These sequelae are persistent effects that manifest after the initial acute phase of the disaster has passed. Examples include chronic respiratory issues from dust, psychological trauma, or lasting physical injuries.

Use this code when documenting a patient's current health problem that is directly attributable to a past cataclysmic storm (e.g., severe blizzard, ice storm, sandstorm, or volcanic eruption) and is no longer in the acute phase. This applies when the patient is being treated for the residual effects of such an event.

• Always code the specific sequela first, followed by this external cause code.
• Ensure documentation clearly links the current condition to a past "other cataclysmic storm."
• This code is for sequelae only; do not use for acute injuries or conditions during the initial event or recovery.
