Other ad food react d/t egg with tolerance to bkd egg, subs

This code describes an allergic or adverse reaction to egg protein, excluding anaphylaxis, in a patient who has previously been diagnosed and is undergoing follow-up care. A key characteristic is that the patient can tolerate baked egg products, indicating a specific sensitivity to raw or lightly cooked egg components.

Use this code for follow-up visits where a patient is being monitored for a non-anaphylactic adverse food reaction to egg, and it has been established that they can safely consume baked egg. This would include appointments for dietary counseling, allergy management plan review, or assessment of ongoing symptoms related to accidental egg exposure.

• Ensure documentation clearly distinguishes between raw/lightly cooked egg intolerance and tolerance to baked egg.
• Verify that the encounter is a "subsequent encounter" (D) and not an initial diagnosis or active treatment (A).
• Do not use for anaphylactic reactions; refer to the T78.0- series for those cases.
