Poisoning by smallpox vaccines, intentional self-harm, subs

This code signifies a deliberate act of self-poisoning using a smallpox vaccine, where the patient is receiving follow-up care for the sequelae of the initial poisoning. It indicates that the patient intentionally ingested, injected, or otherwise administered a smallpox vaccine to themselves with the intent to cause harm. The encounter is for ongoing management of the resulting adverse effects.

Apply this code when a patient presents for treatment of complications arising from a self-inflicted poisoning by a smallpox vaccine, and this is not the initial encounter for the poisoning. This includes situations where the patient is admitted for ongoing monitoring, treatment of organ damage, or psychiatric evaluation following the acute phase of the self-harm event. It is used after the initial emergency treatment has been rendered.

• Always sequence this code after the primary diagnosis describing the specific manifestation or complication of the poisoning.
• Requires an additional code from Chapter 20 (External Causes of Morbidity) to indicate the intent and circumstances of the self-harm.
• Distinguish carefully between intentional self-harm and accidental poisoning or adverse effects of therapeutic use.
