Toxic effect of carbon tetrachloride, self-harm, subs

This code signifies a toxic reaction resulting from the deliberate ingestion or exposure to carbon tetrachloride, occurring during the recovery phase after initial treatment. The patient intentionally harmed themselves using this specific chemical, and the current encounter addresses ongoing care related to that event.

Apply this code for follow-up visits, rehabilitation, or ongoing management of complications arising from a self-inflicted carbon tetrachloride poisoning. This includes situations where the patient is receiving therapy for organ damage (e.g., liver, kidney) or psychological support related to the self-harm attempt.

• Ensure documentation clearly states "intentional self-harm" and "subsequent encounter."
• Always code an external cause code (X60-X84) in conjunction with this code to fully describe the circumstances.
• Do not use for initial treatment of the acute poisoning; a different character in the 7th position would be appropriate for that scenario.
