Summary
Arkansas Blue Cross updated IMRT breast cancer treatment coverage criteria effective 09/01/2026. The policy now specifies that standard whole breast irradiation (WBI) should be 15-16 fractions, with 17-28 fractions allowed only for specific clinical scenarios (nodal involvement, post-mastectomy/reconstruction, dose inhomogeneity, or concurrent chemotherapy). Breast boost limits also changed: up to 8 fractions for patients meeting extended WBI criteria, or up to 5 fractions for others. Billing teams must validate treatment plans against these new criteria to avoid claim denials.
Action Required
By August 31, 2026: Billing team must update prior authorization protocols and claim validation rules in the billing system to enforce the new IMRT breast fractionation criteria. (1) Require clinical documentation indicating which criteria (nodal involvement, post-mastectomy/reconstruction, dose inhomogeneity, or concurrent chemotherapy) justify any treatment plan exceeding 16 fractions of WBI. (2) Configure system edits to flag claims for 17-28 fractions of WBI without documented medical necessity criteria for manual review before submission. (3) Enforce boost fractionation limits: flag claims for >8 fractions boost if extended WBI criteria not met, or >5 fractions boost if standard WBI criteria met. (4) Update provider notification materials and prior auth request forms to reference the new policy criteria. (5) Train billing and prior auth staff on the four qualifying conditions for extended fractionation. Claims submitted without supporting documentation demonstrating medical necessity will be denied as not meeting coverage criteria.
