Toxic effect of sulfur dioxide, self-harm, sequela

This code signifies long-term health problems or residual effects resulting from a deliberate act of self-poisoning with sulfur dioxide. These sequelae are the lasting consequences that manifest after the acute phase of the toxic exposure has resolved.

Apply this code when documenting chronic conditions, permanent organ damage, or persistent neurological deficits directly attributable to a past intentional self-harm attempt involving sulfur dioxide. This would be used in follow-up encounters for ongoing management of these lasting effects.

• Always sequence this sequela code after the code for the specific residual condition being treated.
• Ensure documentation clearly links the current condition to a past intentional sulfur dioxide poisoning.
• Do not use for acute toxic effects; this code is exclusively for sequelae.
