Poisoning by antiviral drugs, intentional self-harm, sequela

This code signifies the long-term effects or complications arising from a deliberate overdose or self-poisoning with antiviral medications. It indicates that the acute phase of the poisoning has passed, but residual health issues directly attributable to the event persist. These sequelae can range from organ damage to neurological deficits.

Apply this code when documenting conditions that are a direct consequence of a past intentional self-harm event involving antiviral drugs. This is appropriate for follow-up visits or when a patient presents with chronic issues linked to such an incident. Do not use for the initial acute poisoning episode.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional antiviral drug poisoning.
• Do not use this code if the poisoning was accidental or undetermined; different codes apply for those circumstances.
