Poisoning by phenothiaz antipsychot/neurolept, undet, init

This code signifies an adverse event resulting from exposure to phenothiazine antipsychotics or other neuroleptics where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is in the acute phase of treatment for this poisoning.

Apply this code when a patient presents with symptoms of phenothiazine or neuroleptic toxicity, and the medical record does not clearly indicate whether the exposure was accidental, intentional, or due to assault. This is appropriate for the initial visit or encounter for this specific poisoning event.

• Always assign an additional code for the specific manifestation(s) of the poisoning.
• Do not use this code if the intent of the poisoning is clearly documented as accidental, intentional self-harm, or assault.
• Ensure the "A" (initial encounter) seventh character is appropriate for the patient's current phase of care for this poisoning.
