Toxic effect of detergents, intentional self-harm, subs

This code signifies a patient presenting for follow-up care related to a previous act of intentional self-harm involving the ingestion or exposure to detergents. The patient is no longer in the acute phase of the poisoning but is receiving ongoing treatment or monitoring for the toxic effects.

This code is appropriate for subsequent encounters where a patient is being managed for complications, sequelae, or ongoing treatment related to a prior self-inflicted detergent poisoning. Examples include follow-up appointments for organ damage assessment, psychiatric evaluation after initial stabilization, or management of persistent symptoms.

• Always sequence this code after the primary diagnosis for the specific toxic effect or complication being treated.
• Ensure documentation clearly indicates the intentional nature of the self-harm and that this is a subsequent encounter.
• Do not use for initial acute poisoning; refer to the appropriate initial encounter code for the acute phase.
