Anaphylactic reaction due to eggs, unspecified, init

This code signifies a severe, life-threatening allergic reaction (anaphylaxis) that occurs after exposure to eggs. The specific type of egg product causing the reaction is not documented. This reaction can involve multiple body systems and requires immediate medical attention.

Apply this code when a patient presents with signs and symptoms of anaphylaxis, and the medical record clearly indicates that the reaction was triggered by eggs, but the specific egg component (e.g., egg white, egg yolk) is not specified. This code is for the initial encounter for this condition.

• Ensure documentation explicitly links the anaphylactic reaction to egg exposure.
• Verify that the encounter is the first time the patient is being seen for this specific reaction.
• If the specific egg component is known (e.g., egg white), a more specific code should be used.
