Poisoning by yellow fever vaccine

This code signifies an adverse reaction or toxic effect resulting from the administration of the yellow fever vaccine. It covers systemic or localized symptoms that are directly attributable to the vaccine itself, rather than an allergic reaction to a component.

Use this code when documentation clearly indicates a patient is experiencing poisoning or a toxic effect specifically from the yellow fever vaccine. This typically involves symptoms like high fever, severe myalgia, or neurological complications directly linked to the vaccine's active ingredients. Documentation should specify "poisoning by" or "toxic effect of" the yellow fever vaccine.

• Distinguish from allergic reactions (e.g., anaphylaxis) to the vaccine, which are coded differently.
• Always sequence this code as the primary diagnosis if it is the reason for the encounter.
• Ensure documentation specifies the type of adverse effect (poisoning/toxic) and the specific vaccine involved.
