Poisoning by inhaled anesthetics, undetermined, init encntr

This code signifies an adverse event where a patient has been poisoned by an inhaled anesthetic, and the intent (accidental, intentional self-harm, assault) cannot be determined. It specifically applies to the initial phase of treatment for such an exposure.

Use this code when documentation clearly indicates poisoning from an inhaled anesthetic, but the provider cannot ascertain whether the exposure was accidental, intentional, or due to an assault. This is appropriate for the first encounter where the poisoning is being evaluated and treated.

• Ensure the documentation explicitly states "undetermined" intent for the poisoning.
• Verify the anesthetic involved was administered via inhalation.
• Confirm this is the initial encounter for the poisoning event.
