Poisoning by lysergide [LSD], assault, sequela

This code signifies the long-term or residual effects resulting from a poisoning by lysergide (LSD) that occurred in the context of an assault. These sequelae can include persistent psychiatric symptoms, cognitive impairments, or other chronic health issues directly attributable to the LSD exposure and the violent nature of its administration. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing the lasting consequences.

Apply this code when documenting a patient presenting with chronic conditions or lasting health problems that are a direct result of a past LSD poisoning where the substance was administered during an assault. This would be used for follow-up visits or when the long-term effects are being treated, rather than the initial acute poisoning. Examples include persistent flashbacks, psychosis, or anxiety disorders attributed to the past event.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current sequela to a past LSD poisoning by assault.
• Do not use this code for acute poisoning; use the appropriate acute poisoning code (T40.8X3A) for initial encounters.
