Toxic effect of strychnine and its salts, self-harm, init

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion or exposure to strychnine or its derivatives, with the intent to harm oneself. Strychnine poisoning typically manifests with severe neurological symptoms, including muscle spasms, convulsions, and respiratory distress.

Apply this code when documentation clearly indicates a patient's symptoms are directly attributable to strychnine toxicity, and the exposure was a conscious act of self-harm. This code is specifically for the initial phase of treatment for such an event, including emergency department visits or initial hospital admissions.

• Ensure documentation explicitly states "intentional self-harm" or similar language regarding the patient's intent.
• Confirm the substance involved is strychnine or one of its salts.
• This "A" suffix indicates an initial encounter for treatment of the poisoning.
