Milt op involving unsp weapon of mass destruction, sequela

This code signifies a long-term health consequence or complication arising from exposure to an unspecified weapon of mass destruction during military operations. It indicates that the initial injury or illness from the WMD event has resolved, but residual effects persist.

Apply this code when documenting chronic conditions, disabilities, or other lasting health problems directly attributable to a past military WMD exposure where the specific type of WMD is not identified. This would include conditions like chronic respiratory issues, neurological disorders, or cancers that develop years after the initial event.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic bronchitis, neuropathy).
• Ensure documentation clearly links the current condition to a past military WMD exposure.
• Do not use this code for acute injuries or illnesses directly resulting from the initial WMD event; those would be coded with the acute phase Y37.91XA or Y37.91XD.
