Frequently Asked Questions
›Why was Xolair denied for my asthma?
Common reasons include: IgE level not documented or outside the 30–1500 IU/mL range, not failing ICS+LABA first, or the prescription not coming from a pulmonologist or allergist. Some plans also require trying Dupixent or Nucala first.
›Does Xolair require an IgE test?
Yes. For asthma, your total serum IgE level must be between 30–1500 IU/mL, and you must have a positive skin test or RAST to a perennial aeroallergen. This test result must be submitted with the PA request.
›Is Xolair covered for food allergies?
Xolair received FDA approval for food allergies in 2024. Coverage is expanding but many payers still classify this as a newer indication with additional documentation requirements. Your allergist should document specific food allergy testing.
