2025 ICD-10-CM code T40.8X1S

Poisoning by lysergide [LSD], accidental (unintentional), sequela.

Use a secondary code from Chapter 20 (External causes of morbidity) to specify the circumstances of the initial accidental poisoning, unless the circumstances are already included in the code. If applicable, use an additional code to identify any retained foreign body (Z18.-). Do not use this code to document birth trauma (P10-P15) or obstetric trauma (O70-O71).

The medical necessity for using T40.8X1S relies on establishing a clear causal link between the initial accidental LSD poisoning and the subsequent long-term health issues experienced by the patient.

Clinicians use this code to document the after-effects of LSD poisoning, which helps track patient outcomes, plan treatments, and understand the long-term impacts of such poisoning.

In simple words: This code indicates long-term health problems that developed after accidental poisoning with LSD.

This code describes the long-term consequences or sequelae resulting from accidental poisoning by lysergide, commonly known as LSD.

Example 1: A patient presents with persistent visual disturbances and flashbacks several months after accidentally ingesting LSD. The code T40.8X1S would be used to document these sequelae., A patient who accidentally took LSD experiences long-term anxiety and depression, which are documented as sequelae using T40.8X1S., Following an incident of accidental LSD poisoning, a patient develops Hallucinogen Persisting Perception Disorder (HPPD). This long-term effect would be recorded using T40.8X1S.

Detailed clinical documentation of the initial LSD poisoning incident, including route of exposure, quantity ingested (if known), and immediate symptoms. Thorough documentation of the long-term effects experienced by the patient, including the nature, onset, severity, and duration of the sequelae. Any diagnostic tests or imaging studies performed to evaluate the sequelae. Treatment plans and interventions implemented to address the long-term consequences of the poisoning.
