Toxic effect of tetrachloroethylene, self-harm, subs

This diagnosis code signifies an adverse health effect resulting from the deliberate ingestion or exposure to tetrachloroethylene, a chemical solvent, with the intent to harm oneself. The "subsequent encounter" indicates that this code is used for follow-up care after the initial treatment for the poisoning.

Apply this code when a patient presents for ongoing management, monitoring, or treatment related to a previous intentional self-poisoning with tetrachloroethylene. This includes appointments for organ damage assessment, mental health follow-up, or management of chronic sequelae. It should not be used for the initial presentation of the poisoning.

• Always sequence this code after the primary diagnosis related to the specific toxic effect (e.g., liver damage, renal failure).
• Ensure documentation clearly states "intentional self-harm" and that the encounter is not the initial treatment.
• Consider additional codes for mental health conditions (e.g., depression, suicidal ideation) if documented and treated during the encounter.
