Toxic effect of chewing tobacco, self-harm, sequela

This code signifies the long-term or residual effects resulting from a deliberate act of self-poisoning with chewing tobacco. It indicates that the patient intentionally ingested or otherwise exposed themselves to chewing tobacco, and the current clinical presentation is a lasting consequence of that event.

Apply this code when documenting conditions that are a direct and permanent result of a past intentional self-harm incident involving chewing tobacco. This would include chronic organ damage, neurological deficits, or other persistent health issues directly attributable to the prior toxic exposure. Do not use for acute poisoning or initial treatment of the self-harm event.

• Requires a seventh character "S" to indicate sequela, meaning the current condition is a late effect of the initial injury.
• Always sequence this code after the code(s) describing the specific sequela (e.g., chronic gastritis, esophageal stricture).
• Ensure documentation clearly links the current condition to a past intentional self-harm event involving chewing tobacco.
