Poisoning by lysergide, accidental (unintentional), subs

This code signifies an accidental overdose or adverse reaction to lysergide (LSD) that is being treated in a follow-up encounter. The patient is no longer in the initial acute phase of treatment but is receiving ongoing care for the effects of the unintentional poisoning.

Apply this code when a patient presents for continued management of symptoms, complications, or sequelae resulting from an accidental LSD poisoning. This includes follow-up appointments for psychiatric evaluation, counseling, or monitoring of physical effects after the initial emergency treatment has concluded.

• Ensure the documentation clearly states the poisoning was accidental and not intentional self-harm or assault.
• Verify that the encounter is a subsequent visit for ongoing care, not the initial treatment for the acute poisoning.
• Always code any associated physical or mental health conditions caused by the LSD poisoning as additional diagnoses.
