2025 ICD-10-CM code T40.8X2S

Sequela of poisoning by lysergide (LSD) due to intentional self-harm.

Code first the nature of the adverse effect.Additional codes may be necessary to specify manifestations of the poisoning.Consult the official ICD-10-CM coding guidelines for further details.

No specific modifiers are typically used with ICD-10-CM codes, though modifiers might apply in certain circumstances based on the context of the clinical encounter.Refer to current billing guidelines.

Medical necessity is established by the presence of persistent and significant health problems directly attributable to the prior intentional LSD overdose. The symptoms must be clinically significant, impacting the patient's quality of life, and requiring ongoing medical intervention or management.

The clinical responsibility includes evaluating the patient's current health status related to the prior LSD poisoning, managing any ongoing symptoms, and providing appropriate treatment and follow-up care. Documentation should include a detailed history of the LSD ingestion, the initial treatment, and the current health status.It is important to rule out other conditions that might mimic the long-term effects of LSD poisoning.

IMPORTANT Consider additional codes from Chapter 20 (External causes of morbidity) to specify the mechanism of injury.Use code Z18.- for any retained foreign body.

In simple words: This code is used when someone has long-term health problems after intentionally taking too much LSD.The initial poisoning is over, but there are still health issues remaining.

This code signifies the late effects (sequelae) resulting from intentional self-harm involving lysergic acid diethylamide (LSD) poisoning.It indicates that the initial poisoning event has resolved, but residual health problems persist.The diagnosis requires documentation of a prior episode of intentional LSD ingestion leading to toxicity and subsequent long-term complications.

Example 1: A patient presents with persistent anxiety, hallucinations, and flashbacks six months after an intentional LSD overdose.The patient had been hospitalized for acute LSD poisoning and received supportive care.The current symptoms are residual effects and indicate the need for coding T40.8X2S., A patient has developed chronic depression and cognitive impairment a year following a suicide attempt involving a large dose of LSD.The initial acute toxicity resolved but the patient still displays significant persistent cognitive and emotional deficits. T40.8X2S would accurately represent these sequelae., A patient reports persistent perceptual distortions and memory problems three years after intentionally taking LSD. These symptoms were not immediately present after the overdose, but developed gradually over time.A psychiatrist confirms the connection between the LSD ingestion and persistent symptoms. T40.8X2S is appropriate to code this case.

Comprehensive documentation is crucial and must include:a detailed history of the intentional LSD ingestion, including the amount and route of administration; documentation of the initial treatment, including hospitalization details if applicable;a thorough physical examination documenting current symptoms and signs; any relevant laboratory or imaging results;and documentation of the long-term effects and their relationship to the prior LSD exposure, ideally including a statement from a qualified healthcare professional establishing the causal link between the intentional ingestion and the long-term symptoms.

** This code is for sequelae only; the initial encounter for acute LSD poisoning would use a different code from the T40.8X series.
