Poisn by mixed bact vaccines w/o a pertuss, self-harm, init

This code signifies an adverse event resulting from the deliberate self-administration of a mixed bacterial vaccine that does not contain a pertussis component. The patient intentionally ingested, injected, or otherwise introduced the vaccine into their system with the intent to cause harm. This code is specifically for the initial phase of treatment for such an event.

Use this code when a patient presents to the emergency department or a healthcare facility after intentionally self-harming with a non-pertussis containing mixed bacterial vaccine. This applies to the initial evaluation and management of the poisoning. Subsequent encounters for the same poisoning event would require a different encounter character.

• Verify documentation clearly states "intentional self-harm" and specifies a "mixed bacterial vaccine without a pertussis component."
• Ensure this is the patient's first encounter for this specific poisoning episode.
• Always code any associated mental health conditions, such as depression or suicidal ideation, as additional diagnoses.
