Toxic effect of dichloromethane, accidental, sequela

This code signifies the long-term or residual health problems resulting from an accidental exposure to dichloromethane. It indicates that the patient has experienced a toxic effect from this chemical, and the current medical issue is a lasting consequence of that unintentional poisoning. This could include chronic organ damage, neurological deficits, or other persistent conditions.

Use this code when documenting a patient presenting with a chronic condition directly attributable to a past, accidental dichloromethane exposure. This applies to follow-up encounters for ongoing management of sequelae, not the initial acute poisoning. Examples include chronic liver disease or persistent neurological symptoms years after an industrial accident involving dichloromethane.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic hepatitis, peripheral neuropathy).
• Ensure documentation clearly links the current condition to a past, accidental dichloromethane exposure.
• The "S" in the 7th character indicates sequela; do not use for acute toxic effects.
