Poisn by electrolytic/caloric/wtr-bal agnt, self-harm, init

This code signifies a patient presenting with an adverse physiological reaction due to the deliberate ingestion or exposure to substances that disrupt the body's electrolyte, caloric, or water balance. This includes agents like excessive diuretics, laxatives, or substances causing severe dehydration or overhydration, where the intent was to cause self-harm.

Apply this code when documenting an initial encounter for a patient who has intentionally poisoned themselves with agents such as potassium supplements, sodium chloride, or other substances primarily affecting fluid and electrolyte homeostasis. This is appropriate for the acute phase of treatment, including emergency department visits and initial hospital admissions.

• Ensure documentation clearly states "intentional self-harm" as the intent.
• Confirm the substance involved primarily affects electrolytic, caloric, or water balance.
• This "A" seventh character is only for the initial encounter for treatment of the poisoning.
