Your primary diagnosis would probably be:
V72.7 Diagnostic skin and sensitization tests (Allergy tests)
I'd use V14.0 as a secondary diagnosis.
I see where the index refers you to 995.27 for drug allergy, but I'm not certain you'd use it in this situation - I would think that poisoning codes are more appropriate for acute episodes, when the patient is experiencing an allergic reaction, but I could be wrong about that. Hope that helps!
