VDP Pharmacy Reenrollment Update

All pharmacies are required to reenroll with the Vendor Drug Program (VDP) to continue receiving payment in fee-for-service and managed care. The Affordable Care Act requires all pharmacies, including those who enrolled with VDP prior to Nov. 2, 2015, to reenroll using the new VDP Pharmacy Provider Enrollment Application. Pharmacies also must submit an application fee, as required by federal law. Some pharmacies may be exempt from the application fee if fees are paid in another state or paid for enrollment as a pharmacy in Medicare.

Pharmacy staff is strongly encouraged to begin filling out the new application now, as it is longer than the previous application and includes new questions. Please submit your completed application, the agreement, the application fee, and all other required documentation by June 17, 2016, to ensure the reenrollment process is completed by September 24, 2016 to avoid potential disruption in payment.

The application, agreement, and other required documents can be downloaded from the VDP website.

Blue Cross and Blue Shield of Texas (BCBSTX) is a managed care plan that serves Texas STAR, CHIP, and CHIP Perinate members in the Texas Travis Service Area and STAR Kids in the Texas Travis and MRSA Central Service Area.

The goal of our pharmacy benefit is ensure that members receive therapeutically appropriate drug therapy.

Select drugs may require prior authorization.
