Anaphylactic reaction due to food additives, sequela

This code signifies a long-term or late-occurring health problem resulting from a severe, life-threatening allergic reaction (anaphylaxis) that was triggered by food additives. It indicates that the acute anaphylactic episode has resolved, but the patient is experiencing residual effects or complications directly attributable to that past event.

Use this code when documenting a patient presenting with a chronic condition or persistent symptom that is a direct consequence of a previously experienced anaphylactic reaction to food additives. This applies to situations where the initial acute event has passed, but its lasting impact on the patient's health is being addressed.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past anaphylactic event caused by food additives.
• Do not use for acute anaphylaxis; this code is exclusively for the long-term effects.
