Anaphyl reaction due to egg with rct to baked egg, init

This code signifies a severe, systemic allergic reaction (anaphylaxis) specifically triggered by egg consumption, where the patient has also demonstrated reactivity to baked egg products. This indicates a persistent and potentially more severe form of egg allergy, as some individuals can tolerate baked egg despite raw egg allergy. The "initial encounter" denotes that this is the first time the patient is being seen for this specific condition.

Use this code when documenting an acute anaphylactic episode caused by egg exposure, and the patient's history or current presentation confirms reactivity even to egg that has been cooked (baked). This is appropriate for the initial diagnosis and treatment of such an event in an emergency department or outpatient setting.

• Always ensure documentation clearly specifies "anaphylaxis" and the causative agent is "egg," with noted reactivity to "baked egg."
• Verify the "initial encounter" designation; subsequent encounters for the same condition would use a different seventh character.
• Consider co-reporting with codes for any associated symptoms or treatments, such as epinephrine administration.
