Poisoning by oth psychodysleptics, undetermined, init encntr

This code signifies an accidental or intentional poisoning event involving a hallucinogenic substance not otherwise specified, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is in the acute phase of treatment for the toxic effects of the substance.

Use this code when a patient presents with symptoms of poisoning due to a hallucinogen, and the medical record does not clearly document whether the exposure was accidental, intentional, or due to assault. This is appropriate for the initial encounter for treatment of the poisoning.

• Always assign an additional code for the manifestations of the poisoning.
• Do not use this code if the specific hallucinogen is known; instead, use a more specific code from the T40.9X- subcategory.
• Ensure the "A" seventh character for initial encounter is appropriate for the patient's current phase of care.
