Poisoning by lysergide, accidental (unintentional), sequela

This code signifies a long-term or residual effect stemming from an accidental overdose or exposure to lysergide (LSD). It indicates that the acute poisoning event has resolved, but the patient continues to experience persistent health problems directly attributable to the LSD intoxication. These sequelae can manifest as various physical or psychological impairments.

Apply this code when documenting a patient presenting with chronic or lasting conditions that are a direct consequence of a previously sustained, unintentional lysergide poisoning. This would include scenarios where a patient is being treated for persistent psychosis, flashbacks, or other enduring neurological or psychiatric disturbances clearly linked to an accidental LSD exposure that occurred in the past.

• Always sequence this sequela code after the code for the specific residual condition being treated.
• Ensure documentation clearly links the current condition to a past accidental lysergide poisoning.
• Do not use for acute poisoning events; this code is exclusively for the long-term effects.
