Poisoning by oth viral vaccines, intentional self-harm, subs

This code signifies a poisoning event resulting from the deliberate self-administration of an excessive or inappropriate dose of a viral vaccine, with the intent to cause harm. This specific code is used when the patient is receiving follow-up care for the initial poisoning episode.

Apply this code when documenting subsequent encounters for a patient who intentionally poisoned themselves with a viral vaccine. This includes follow-up appointments for monitoring, managing lingering side effects, or addressing complications arising from the initial self-harm attempt. It would be used after the acute phase of treatment for the poisoning.

• Always sequence this code after the primary diagnosis indicating the nature of the poisoning's effects.
• Ensure documentation clearly specifies "intentional self-harm" and "subsequent encounter" to justify this code.
• Verify the substance involved was indeed a "viral vaccine" and not another type of vaccine or medication.
