Jun 20, 2026
Summary
Blue Cross Blue Shield of Mississippi has updated their fetal surgery policy, defining specific medical necessity criteria for in utero procedures including vesico-amniotic shunting, pulmonary tissue resection, sacrococcygeal teratoma removal, and myelomeningocele repair. The policy establishes clear gestational age limits and clinical requirements for coverage while marking certain procedures like tracheal occlusion and cardiac interventions as investigational.
Action Required
Immediately: Review all pending and future fetal surgery cases to ensure they meet the new medical necessity criteria outlined in the policy. Maternal-fetal medicine specialists and billing staff must verify gestational age limits (32 weeks or less for certain procedures, less than 26 weeks for myelomeningocele), presence of fetal hydrops or maternal mirror syndrome where required, and absence of exclusionary conditions. Update prior authorization requests to include these specific clinical criteria and flag investigational procedures that may not be covered.
