2025 ICD-10-CM code T40.8X4A

Poisoning by lysergide [LSD], undetermined intent, initial encounter.

Refer to the official ICD-10-CM coding guidelines for complete instructions on coding poisoning and adverse effects of drugs.Always code the underlying cause, in this case, LSD poisoning, as the primary code.

Modifiers may be applicable depending on the circumstances of the encounter and the services provided.Consult the appropriate payer-specific guidelines.

Medical necessity is established by the presence of LSD poisoning, requiring immediate medical intervention to manage the symptoms, prevent complications, and stabilize the patient. Treatment is necessary to address the acute effects and potential long-term consequences of LSD toxicity.

The clinical responsibility involves diagnosing the poisoning, managing the patient's symptoms, and providing appropriate treatment to stabilize the patient and mitigate the adverse effects of LSD. This may include supportive care, managing complications, and providing counseling on substance use.

IMPORTANT If the intent is known (accidental, self-harm, assault), use the corresponding 7th character code (T40.8X1A, T40.8X2A, T40.8X3A).Additional codes might be necessary to capture other injuries or conditions resulting from the LSD poisoning.

In simple words: This code is used when someone is poisoned by LSD, and it's not clear if it was accidental, on purpose, or caused by someone else. This is for the first time this poisoning is recorded.

This code classifies the initial encounter for poisoning due to lysergide (LSD), where the intent (accidental, self-harm, assault) is undetermined.It's crucial to specify the intent if known using the appropriate 7th character.Additional codes may be necessary to specify manifestations of poisoning or the use of other substances involved. This code is part of the broader category of poisoning by narcotics and psychodysleptics and should be used in accordance with the official ICD-10-CM coding guidelines.

Example 1: A patient presents to the emergency department after ingesting an unknown substance.Lab tests confirm the presence of LSD. The intent of ingestion is unclear., A patient is found unconscious. Upon investigation, it's determined the patient had ingested LSD. The circumstances surrounding the ingestion are unknown., A patient is brought to the hospital by law enforcement after being found in a state of altered consciousness. LSD poisoning is suspected. The method of exposure is undetermined during initial assessment.

Complete documentation should include the patient's history (including substance use), physical examination findings, laboratory results confirming LSD poisoning, details about the circumstances surrounding the event (including the intent and the method of exposure),treatment provided, and the patient's response to treatment.

** This code should be used for initial encounters only.Subsequent encounters should utilize the appropriate seventh character code (e.g., T40.8X4D for subsequent encounter).If other drugs or substances were involved, those should also be coded.
