Summary
BCBS Arizona has issued a new Evidence-Based Criteria policy (effective 01/20/26) classifying four adjunctive esophageal screening and surveillance technologies as experimental or investigational: EsoCheck, EsoGuard, Esopredict, and WATS3D. These tests are not covered for screening, surveillance, or risk stratification of Barrett esophagus and esophageal dysplasia unless they meet specific clinical criteria or prior authorization is obtained.
Action Required
By January 20, 2026: Billing team must implement the following changes: (1) Flag all claims for EsoCheck, EsoGuard, Esopredict, and WATS3D procedures as requiring prior authorization before submission to BCBS Arizona; (2) Update billing system denial protocols to automatically deny these services without prior auth documentation; (3) Notify gastroenterology providers and clinical staff that these adjunctive screening tests are classified as experimental/investigational and require medical necessity documentation and prior authorization; (4) Add these tests to the practice's prior authorization checklist and EMR reminders; (5) Train billing staff to request detailed clinical rationale from providers when submitting exception requests per policy language. Claims submitted without prior authorization or medical justification will be denied by BCBS Arizona.
