Poisoning by unsp drug/meds/biol subst, self-harm, init

This code signifies a patient presenting with an adverse physiological reaction due to the ingestion, injection, or exposure to an unspecified drug, medication, or biological substance, where the intent was self-harm. The patient is in the initial phase of treatment for this poisoning event.

Apply this code when documentation clearly indicates a poisoning from an unspecified substance with suicidal intent, and the patient is receiving active treatment for the acute effects of the poisoning. This includes emergency department visits, initial hospital admissions, or the first encounter with a healthcare provider for this specific event.

• Ensure the documentation explicitly states "intentional self-harm" or "suicidal intent" for the poisoning.
• Verify that the specific drug, medicament, or biological substance causing the poisoning is not identified in the medical record.
• Confirm this is the initial encounter for the poisoning; subsequent encounters will require a different seventh character.
