Anaphyl react due to egg with tolerance to baked egg, subs

This code describes a patient experiencing an anaphylactic reaction specifically caused by egg exposure, where the patient has demonstrated the ability to tolerate baked egg products. This indicates a specific type of egg allergy, often less severe than a full egg allergy, but still capable of causing a life-threatening systemic reaction.

Use this code for follow-up encounters with patients who have a documented history of anaphylaxis to egg, but have successfully passed an oral food challenge or otherwise demonstrated tolerance to baked egg. This is applicable when managing their ongoing allergy, providing education, or monitoring for future reactions.

• Ensure documentation clearly distinguishes between raw/cooked egg allergy and tolerance to baked egg.
• Verify the encounter is indeed a "subsequent encounter" as indicated by the 7th character.
• Do not use if the patient has a general egg allergy without documented tolerance to baked egg.
