Other ad food react d/t egg with bkd egg tol/rct, unsp, subs

This code signifies a patient's adverse reaction to egg, specifically when a tolerance or reactivity to baked egg has been established, and the encounter is for follow-up care. It indicates that the reaction is not anaphylactic and the specific type of adverse reaction (e.g., gastrointestinal, dermatological) is not documented.

Use this code for subsequent encounters when a patient with a known baked egg tolerance or reactivity experiences an adverse reaction to egg. This is appropriate for follow-up visits after initial diagnosis and treatment, or for ongoing management of the condition. It should be applied when the specific nature of the adverse reaction is not further specified.

• Ensure documentation clearly states a "subsequent encounter" for the adverse reaction.
• Verify that the patient has a documented baked egg tolerance or reactivity.
• Do not use this code if the adverse reaction is anaphylactic; a more specific code would be required.
