Renewing Vimizim (Elosulfase Alfa) Approval with Blue Cross Blue Shield of Texas: 2025 Requirements & Timeline

Answer Box: Vimizim Renewal with Blue Cross Blue Shield of Texas

Good news for HealthSelect members: As of September 2024, Blue Cross Blue Shield of Texas HealthSelect plans no longer require prior authorization for Vimizim (elosulfase alfa) renewals. However, you still need an in-network PCP referral on file. For other BCBS Texas plans, annual reauthorization typically requires updated functional assessments (6-minute walk test), urine GAG levels, and documentation of continued clinical benefit. Start your renewal process 60-90 days before your current authorization expires to avoid treatment interruptions.

First step today: Contact your prescriber to schedule baseline assessments and verify your specific BCBS Texas plan requirements at bcbstx.com.
