2025 ICD-10-CM code T40.8X1D

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

Use secondary codes from Chapter 20 (External causes of morbidity) to indicate the cause of injury, unless the T-code already includes the external cause.

Medical necessity is established by the patient's presentation with symptoms, signs, or circumstances indicating a need for evaluation and treatment due to accidental LSD poisoning. Subsequent encounters are medically necessary if ongoing care is required to manage the effects of the poisoning.

The healthcare provider is responsible for accurately documenting the patient's accidental LSD poisoning and its effects, which would include symptoms, vital signs, treatment provided, and response to treatment.

In simple words: This code indicates an unintentional poisoning by LSD (lysergic acid diethylamide) and signifies a follow-up visit for this condition.

Poisoning by lysergide [LSD], accidental (unintentional), subsequent encounter. This code is used for subsequent encounters for patients who have accidentally ingested or been exposed to LSD.

Example 1: A patient was brought to the ER last week after unintentionally ingesting LSD at a party. He is now returning for a follow-up evaluation and management of persistent symptoms., A patient was treated in the emergency room a few days ago for accidental LSD poisoning. Today, they present to their primary care physician for a follow-up check-up and continued monitoring of their condition., A teenager accidentally consumed a cookie laced with LSD. Following initial treatment, they now present to a substance abuse clinic for ongoing support and counseling, categorized as a subsequent encounter related to the poisoning.

Documentation should include the details of the LSD exposure, symptoms experienced, treatment provided, and the patient's current condition. Any long-term effects or complications should also be noted.

** This is a subsequent encounter code. For the initial encounter, use T40.8X1A. An additional code may be required to identify any retained foreign body, if applicable (Z18.-).
