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

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion, exposure, or administration of a substance not otherwise specified, with the explicit intent of self-harm. The toxic effect is due to a substance that doesn't have a more specific ICD-10-CM code for its toxic effect.

Apply this code when a patient is admitted or seen for the initial treatment of poisoning or other toxic effects caused by an unspecified substance, and the medical record clearly documents the intent as self-harm. Examples include an overdose of an unknown medication or chemical, or exposure to a non-specific toxic agent, where the patient intended to harm themselves.

• Always sequence this code after the specific poisoning or toxic effect code, if known.
• Ensure the medical record explicitly states "intentional self-harm" or similar language to support the intent.
• This "initial encounter" indicator is used as long as the patient is receiving active treatment for the toxic effect.
