2025 ICD-10-CM code T40.8X

Poisoning by and adverse effect of lysergide [LSD].

Follow the official ICD-10-CM coding guidelines for poisoning and adverse effects.Always code the principal diagnosis and any associated conditions.Ensure proper sequencing of codes to reflect the clinical picture.Always use the most specific code available.

Medical necessity for coding T40.8X is established by documented evidence of LSD exposure and the presence of clinical findings consistent with LSD toxicity.The necessity of treatment and interventions should be clearly explained in the medical record.For cases of accidental exposure, the source of exposure must be identified and documented.

The clinical responsibility for this code involves accurate documentation of the LSD exposure (intentional or accidental), the patient's presentation (symptoms and signs of toxicity), treatment administered, and monitoring for complications.Thorough documentation of adverse effects is paramount for appropriate coding and billing.

IMPORTANT Use additional code(s) to specify manifestations of poisoning.Code first the nature of the adverse effect (e.g., adverse effect NOS (T88.7)).The drug causing the adverse effect should be identified using codes from categories T36-T50 with fifth or sixth character 5.Also, use additional code(s) to indicate the cause of injury (Chapter 20, External causes of morbidity).For underdosing, use codes Y63.6, Y63.8-Y63.9, or Z91.12-, Z91.13-.

In simple words: This code is used for cases of poisoning or bad reactions from LSD.This includes taking too much LSD by accident or on purpose, or having a reaction even when the LSD was given as medicine.Other codes might be needed to explain exactly what happened.

This ICD-10-CM code classifies poisoning by and adverse effects of lysergide (LSD), a potent hallucinogenic drug.The code encompasses both intentional ingestion (overdose) and accidental exposure, as well as adverse reactions to appropriately administered therapeutic doses.It's crucial to note that additional codes should be used to specify the manifestations of poisoning.Further, this code excludes drug dependence and related mental and behavioral disorders stemming from psychoactive substance use.

Example 1: A 20-year-old male presents to the emergency department after ingesting an unknown quantity of LSD. He exhibits profound anxiety, visual hallucinations, and tachycardia.Treatment includes supportive care and observation., A 35-year-old female, who is undergoing experimental treatment for depression, experiences adverse effects (e.g., severe nausea and vomiting) after a prescribed dose of LSD.Treatment focuses on alleviating these symptoms. Note: Additional codes would be required to document these symptoms., A 17-year-old male is found unconscious and unresponsive; LSD is found at the scene. Emergency services stabilize him for transport to the hospital. Extensive lab work is performed to ascertain the extent and impact of the poisoning. Additional codes would be needed to represent the specific symptoms/diagnosis.

Detailed patient history outlining the circumstances of LSD exposure (amount ingested, route of administration, time of ingestion).Complete physical examination noting vital signs, neurological status, and presence of any symptoms.Laboratory results including blood and urine toxicology reports.Documentation of treatment administered and response to therapy. Complete record of the patient’s progress and status before discharge.

** Consider using additional codes to capture specific symptoms or complications.Always consult the latest version of the ICD-10-CM coding manual for updates and clarifications.
