Toxic effect of oth substances, intentional self-harm, subs

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion or exposure to a substance not specifically categorized elsewhere, with the intent to harm oneself. This encounter represents follow-up care after the initial treatment for the toxic effect.

Apply this code for subsequent visits related to the management of complications or ongoing treatment for a self-inflicted poisoning by an unspecified substance. This includes follow-up appointments for organ damage, psychological evaluation, or monitoring after discharge from acute care.

• Ensure the documentation clearly states "intentional self-harm" and that the substance is "other specified" but not more precisely defined.
• Confirm this is a subsequent encounter, not the initial presentation for the toxic effect.
• Always sequence this code after the primary diagnosis for the specific toxic effect, if known and applicable.
