Poisoning by lysergide, undetermined, initial encounter

This code signifies a case of poisoning due to lysergide (LSD) where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined from the available documentation. The "initial encounter" designation indicates that the patient is receiving active treatment for the acute effects of the poisoning.

Apply this code when a patient presents with symptoms of LSD intoxication or adverse effects, and the medical record clearly states or implies that the intent of the exposure is unknown or unspecified. This is appropriate for the first visit or admission related to this specific poisoning event.

• Always sequence this code first when it represents the primary reason for the encounter.
• Do not use this code if the intent of the poisoning (e.g., accidental, intentional self-harm) is clearly documented; instead, choose the appropriate intent-specific code.
• Ensure documentation supports "initial encounter" for active treatment; subsequent care for the same poisoning would use a different encounter character.
