Poisoning by unspecified narcotics, assault, init encntr

This code signifies a patient presenting with an adverse physiological reaction due to the intentional administration of an unspecified narcotic by another person with the intent to harm. The patient is in the acute phase of treatment for this poisoning.

Apply this code when documentation clearly indicates a narcotic poisoning resulting from an assault, and the specific narcotic agent is not identified. This is appropriate for the initial hospital visit or encounter where the poisoning is first evaluated and treated.

• Ensure documentation explicitly states "assault" or similar intent by another party.
• Only use for the initial encounter; subsequent care requires a different seventh character.
• Do not use if the specific narcotic is known; instead, code to the specific substance.
