Poisoning by unsp antidepressants, undetermined, init encntr

This code signifies a patient presenting with adverse effects from an antidepressant where the specific type of antidepressant is unknown, and the intent (e.g., accidental, intentional self-harm) of the exposure cannot be determined. It indicates the initial phase of treatment for this poisoning event.

This code is appropriate for emergency department visits or initial inpatient admissions where a patient is experiencing symptoms of antidepressant poisoning, but the exact antidepressant ingested is not yet identified, and the circumstances surrounding the ingestion are unclear. It should be used when documentation explicitly states "undetermined" intent.

• Only use for the initial encounter of treatment for this specific poisoning event. Subsequent encounters would use a different seventh character.
• Ensure documentation clearly supports "unspecified antidepressant" and "undetermined" intent.
• Avoid using this code if the specific antidepressant or the intent of the poisoning is known or can be reasonably inferred from the medical record.
