Poisoning by inhaled anesthetics, self-harm, init

This code signifies a patient presenting with adverse effects from intentionally self-administering inhaled anesthetics with the intent to cause harm. This includes symptoms such as respiratory depression, cardiac arrhythmias, or central nervous system depression resulting from the deliberate misuse of these substances. The "initial encounter" designation indicates the patient is actively receiving treatment for the acute phase of this poisoning.

Apply this code when documenting a patient admitted to the emergency department or hospital following a suicide attempt involving the inhalation of anesthetic gases. This would include scenarios where a patient is found unresponsive after exposure to substances like nitrous oxide or volatile anesthetics, and a clear intent of self-harm is established. It is used for the initial assessment and treatment of the acute poisoning event.

• Always confirm the intent of self-harm through documentation; if accidental, a different intent code is required.
• Ensure the "initial encounter" is appropriate for the patient's current phase of care for this specific poisoning event.
• Code any associated physical injuries or mental health diagnoses separately to provide a comprehensive clinical picture.
