2025 ICD-10-CM code T50.A12

Poisoning due to intentional self-harm by pertussis vaccine, including combinations containing a pertussis component.

Use additional codes to identify the specific manifestations of the poisoning (e.g., nausea, vomiting, seizures) and any underlying mental health conditions.

Medical necessity is established by the presence of symptoms and the need for medical intervention due to the poisoning event.

Clinicians should document the circumstances surrounding the self-harm, the specific vaccine involved, and the resulting symptoms and treatment.

In simple words: Intentional overdose of pertussis vaccine resulting in poisoning.

This code represents a poisoning event resulting from intentional self-harm involving a pertussis vaccine or any combination vaccine containing a pertussis component.

Example 1: A patient intentionally ingests a large quantity of pertussis-containing vaccine in a suicide attempt, resulting in symptoms of poisoning., An adolescent intentionally injects themselves with an excessive dose of pertussis vaccine, leading to adverse effects and requiring medical intervention., A patient deliberately consumes expired pertussis vaccine, causing symptoms of poisoning and needing treatment.

Documentation should include the type and amount of vaccine ingested, the method of self-harm, the time elapsed since ingestion/administration, the patient's presenting symptoms, and any treatment provided.

** It's crucial to differentiate between accidental and intentional poisoning.A secondary code from Chapter 20, External causes of morbidity (V01-Y99), should be used to indicate the cause of injury (intentional self-harm).
