Provider Actions / Prior Authorization

Prior Authorization

Initial prior authorization required with specialty prescriber

Initial prior authorization required with specialty prescriber. Initial authorization requires documentation that all specified clinical criteria are met and that prescriber is an appropriate specialist. Initial authorization will be for no more than 12 months. HCPCS code J2357 applies (Injection, omalizumab, 5 mg).

Specialist prescriber (allergist/immunologist, pulmonologist, dermatologist, otolaryngologist as indicated)
Initial authorization limited to no more than 12 months
Drug HCPCS code: J2357 (injection, omalizumab, 5 mg)

Documentation Required

Document baseline laboratory and testing

Document baseline laboratory and testing. For asthma, baseline (pre-omalizumab) serum total IgE must be documented as greater than or equal to 30 IU/mL and less than or equal to 1300 IU/mL, and a positive skin test or in vitro reactivity to a perennial aeroallergen must be documented.

Clinical Evidence

68%Peanut ≥600 mg DBPCFC response (Xolair) vs placebo 5% — treatment difference 63% (95% CI 50–73)

65%Peanut ≥1000 mg response (Xolair) vs placebo 0% — difference 65% (95% CI 56–74)

24.5%ICATA: symptom days reduced by 24.5% (1.96→1.48 days per 2 weeks); exacerbations 30.3% vs 48.8%

300mgCIU/CSU: Omalizumab 300 mg reduced weekly itch severity score and met multiple secondary endpoints (significant vs placebo)

A systematic review and meta-analysis of randomized trials in seasonal (and perennial) allergic rhinitis (11 RCTs, 2,870 patients) found a reduction in daily nasal symptom severity score (SMD -0.67, 95% CI -1.3 to -0.31) and a reduction in daily nasal rescue medication score (SMD -0.22, 95% CI -0.39 to -0.05), with no significant difference in occurrence of any adverse event (RR 1.06, 95% CI 0.94–1.19).

Open-label studies in perennial allergic rhinitis (Corren et al.) using IV dosing 0.015–0.03 mg/kg/IgE reported decreases in free IgE up to 99% and reduced nasal allergen challenge symptom scores; a randomized trial (Chervinsky) of subcutaneous dosing ≥ 0.016 mg/kg/IgE every 4 weeks over 16 weeks reduced daily nasal severity score by 69% vs 49% for placebo (p=0.001) and achieved symptom control (<0.75) in 28% vs 10%.

Background

Omalizumab is a monoclonal antibody that binds to IgE's high‑affinity Fc receptor, preventing IgE binding to effector cells and reducing allergic mediator release; clinical trials have shown reductions in free serum IgE (> 90%) and effects on eosinophils and allergic responses.

Omalizumab is approved by the U.S. Food and Drug Administration for allergic asthma (adults and adolescents ≥ 6 years with positive perennial aeroallergen reactivity), chronic idiopathic urticaria (≥ 12 years), chronic rhinosinusitis with nasal polyps (≥ 18 years), and IgE‑mediated food allergy (≥ 1 year, as adjunct to allergen avoidance); it is not indicated for acute bronchospasm or status asthmaticus.

This policy summarizes efficacy and safety evidence from randomized clinical trials and observational studies across these indications (including asthma, chronic urticaria, nasal polyps, and IgE‑mediated food allergy) and provides patient selection criteria for provider‑administered Xolair.

Guideline organizations (e.g., GINA, ERS/ATS) provide recommendations and phenotype/biomarker considerations to guide biologic use in severe asthma, which are referenced in the policy.

Key definitions

Positive clinical responseReduction in exacerbations, decreased rescue medication use, increase in percent predicted FEV1 from pretreatment baseline, or reduction in severity/frequency of disease‑specific symptoms (examples listed per indication)

Coverage Rationale (revision note)

Revised coverage criteria language as of 10/01/2025:

Patient is not receiving any of the listed therapies in combination with Xolair for treatment of the same indication

Replaces prior broader prohibition language

Baseline total serum IgE ≥ 30 IU/mL and ≤ 1300 IU/mL
Positive skin test or in vitro reactivity to a perennial aeroallergen

Documentation Required

Document trial and response to prior therapies

Document trial and response to prior therapies. For each indication providers must document prior therapy trials and lack of adequate response or contraindication/intolerance as specified (examples: for asthma — prior use of maximally dosed ICS/LABA or maximally dosed ICS plus an additional controller; for chronic urticaria — trial of two H1-antihistamines or combination antihistamine therapy; for nasal polyps — trial of intranasal corticosteroids and one other therapy such as saline irrigation or antileukotriene; for food allergy — allergen avoidance and access to epinephrine).

Asthma: maximally-dosed ICS/LABA or maximally-dosed ICS plus an additional controller medication
Chronic urticaria: trial of two H1-antihistamines or combination antihistamine regimens
Nasal polyps: trial of intranasal corticosteroids and one other therapy (e.g., saline irrigation, antileukotriene)
Food allergy: allergen avoidance and documentation of access to epinephrine

Denial Risk

Concurrent biologic therapy exclusion

Concurrent biologic therapy exclusion. Claims may be denied if the patient is receiving Xolair in combination with anti-IL-4, anti-IL-5, or TSLP inhibitor therapies for treatment of the same indication.

Anti-IL-4 example: dupilumab
Anti-IL-5 examples: mepolizumab, reslizumab, benralizumab
TSLP inhibitor example: tezepelumab
Applies when used in combination for the same indication

Prior Authorization

Reauthorization requirements

Reauthorization requirements. Reauthorization requires documentation of positive clinical response (examples provided per indication) and reauthorization will be for no more than 12 months.

Document positive clinical response (e.g., reduced exacerbations, decreased rescue medication use, improved FEV1, reduced symptom severity)
Reauthorization limited to no more than 12 months

Documentation Required

Reference member-specific benefits

Reference member-specific benefits. When deciding coverage, reference the member specific benefit plan document; in the event of a conflict, the member-specific benefit plan governs.

Member specific benefit plan may differ from policy and governs if conflict exists

Documentation Required

Use of external criteria tools

Use of external criteria tools. UnitedHealthcare may use third-party tools, such as InterQual, to assist in administering benefits; providers should anticipate requests consistent with those tools.

Third-party example: InterQual

Prior Authorization

Revised combination therapy exclusion qualifier

Revised combination therapy exclusion qualifier. Coverage criteria were revised effective 2025-10-01 to specify that the patient must not be receiving listed therapies in combination with Xolair for treatment of the same indication; prior authorization decisions should apply this updated language.

Effective date: October 1, 2025
Qualifier: 'for treatment of the same indication'

A 16‑week randomized, placebo‑controlled pilot trial in atopic dermatitis (n=20) showed reductions in free IgE with omalizumab but did not demonstrate significant improvement in clinical disease activity.

FDA informational labeling notes approvals for moderate to severe persistent allergic asthma (≥ 6 years), chronic idiopathic urticaria (≥ 12 years), chronic rhinosinusitis with nasal polyps (≥ 18 years), and IgE‑mediated food allergy (≥ 1 year) as adjunct to avoidance, and states that Xolair is not indicated for acute bronchospasm or status asthmaticus.

Clinical guideline recommendations include GINA (2024) supporting add‑on omalizumab for severe allergic asthma (aged ≥ 6 years, Evidence A) and ERS/ATS guidance providing phenotype and biomarker cut-offs (e.g., eosinophil and FENO thresholds) to help guide biologic selection.

Randomized trial data in IgE‑mediated food allergy (peanut and other foods) demonstrated clinically meaningful increases in tolerance (e.g., peanut ≥ 600 mg response: 68% vs 5%, treatment difference 63%, 95% CI 50–73; peanut ≥ 1000 mg response: 65% vs 0%, treatment difference 65%, 95% CI 56–74).

Xolair administered by a healthcare professional (self‑administered formulation is covered under pharmacy benefit and not included in this provider‑administered policy)

Uncontrolled asthmaPoor symptom control and/or frequent exacerbations (>= 2/year requiring OCS) or serious exacerbations (>= 1/year requiring hospitalization)

Difficult‑to‑treat asthmaAsthma uncontrolled despite medium/high‑dose ICS with a second controller or maintenance OCS, or requires high‑dose treatment to maintain control

Severe asthmaAsthma uncontrolled despite adherence with optimized high‑dose ICS‑LABA and management of contributory factors, or worsens when high‑dose treatment is decreased
