Coverage summary

Prior authorization request form to document clinical criteria for use of IL-4/IL-13/IL-31 inhibitors across multiple indications for Washington Apple Health members. The form operationalizes coverage rules and collects required clinical data, including patient and prescriber information, indication-specific severity measures, phenotype markers, prior medication trials with durations, and objective evidence (e.g., endoscopy/biopsy, FEV1, BSA/IGA/EASI) to support medical necessity. Requests may be for initial or continuation of therapy; continuation requires documentation demonstrating disease stability or a positive clinical response as defined per indication. Coverage stance: covered_with_criteria.

Atopic dermatitis - EASI improvement>= 50% decrease from baseline

Atopic dermatitis - BSA reduction (continuation)>= 20% reduction from baseline

Prurigo nodularis - nodules>= 20 nodules for at least 3 months

Background and scope

This multi-indication prior authorization form documents that members meet indication-specific severity, phenotype, prior therapy trials, and response criteria for IL-4/IL-13/IL-31 inhibitors under Washington Apple Health. It captures patient weight, prescriber specialty, whether the request is a continuation, and requires chart notes and objective diagnostic evidence where applicable.

For each listed indication the form collects: indication-specific severity measures (e.g., BSA ≥ 10% or IGA ≥ 3 for atopic dermatitis; asthma severity classification and blood eosinophils ≥150 cells/µL for eosinophilic phenotype; bilateral sinonasal polyposis by endoscopy/CT for CRSwNP; EoE symptoms plus histology with peak ≥15 eos/hpf; prurigo nodularis nodules count and WI-NRS ≥7; COPD lung function and eosinophil thresholds), documentation of prior therapy trials with minimum trial durations (examples: topical and systemic corticosteroids, inhaled controller regimens, PPIs, swallowed topical steroids, intranasal corticosteroids, phototherapy, systemic immunosuppressants), and evidence of treatment response for continuation requests.

The form operationalizes coverage rules by requiring completion of all applicable fields, submission of chart notes and objective test results (e.g., endoscopy/biopsy, CT, FEV1, exacerbation history, BSA/IGA/EASI scores), listing prior preferred AHPDL agent trials or reasons they were not tried, and instructing submission to the specified fax/phone with at least 24 hours allowed for review. Incomplete forms or missing documentation may delay or lead to denial.
