Wiki E code for environmental allergies

[marymurk]

Does anyone have any suggestion for an e-code to be used when the reaction is caused by environment or even unknown. Our abstracting program requires an e-code - would appreciate any input.

What Dx code are you using for "environmental allergies"? To me, environmental allergies would be more in line with rhinitis in the 477 range and not a toxic or anaphylactic reaction in the 995 range
