Poisoning by smallpox vaccines, self-harm, sequela

This code signifies long-term health problems or conditions that arise from a deliberate act of self-poisoning using smallpox vaccines. It indicates that the patient intentionally administered the vaccine to themselves with the intent to cause harm, and is now experiencing residual effects from that event. These sequelae can manifest in various ways depending on the specific vaccine and the patient's reaction.

Use this code when documenting a patient presenting with chronic or residual health issues directly attributable to a past, intentional self-administration of a smallpox vaccine. This applies to follow-up encounters for conditions that developed as a result of the self-harm incident, even if the acute poisoning event occurred in the distant past. It is appropriate for cases where the patient's current symptoms are a direct consequence of the previous self-poisoning.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic skin lesions, neurological damage).
• Ensure documentation clearly states the intentional nature of the self-harm and the causal link between the smallpox vaccine and the current sequelae.
• Do not use this code for acute poisoning events; it is specifically for the long-term effects.
