Poisoning by antiviral drugs, intentional self-harm, init

This code signifies a patient presenting with adverse effects resulting from the deliberate self-administration of antiviral medications with the intent to cause harm. The patient is in the initial phase of receiving active treatment for this poisoning.

This code is appropriate for documenting cases where a patient has intentionally overdosed on antiviral drugs, such as those used for HIV, hepatitis, or influenza, and is currently undergoing evaluation and management in an emergency department or inpatient setting. It should be used when the primary reason for the encounter is the acute poisoning event and its immediate treatment.

• Always assign an additional code for the specific antiviral drug involved, if known (e.g., from categories T37.51-T37.59).
• Ensure the "A" seventh character (initial encounter) is used only for the period when the patient is receiving active treatment for the poisoning.
• Consider co-reporting with codes for underlying mental health conditions, if applicable, such as depression or suicidal ideation.
