2025 ICD-10-CM code T40.8X2A

Poisoning by lysergide [LSD] due to intentional self-harm, initial encounter.

Use a secondary code from Chapter 20, External causes of morbidity, to indicate the cause of the injury. An additional code from category Z18.- should be used if there's a retained foreign body.If there are any adverse effects from the LSD poisoning, those conditions should be coded separately.

Medical necessity for the use of T40.8X2A is established by the patient's presentation with symptoms of LSD poisoning due to intentional self-harm and the need for medical intervention to manage the poisoning.

Clinical responsibility for this code includes assessing the patient's condition, providing appropriate medical care, and documenting the circumstances of the self-harm. This may involve consultation with mental health professionals and social workers for further evaluation and treatment of the underlying cause of the self-harm.
