Earlier this year, we advised you of an upcoming transition to a new operating platform for our core processing activities to help us gain efficiencies and lower operating costs. This transition will also help us to add new capabilities that enhance the overall customer experience. IBC will be using Highmark's operating platforms to handle core processing functions such as enrollment, claims, and billing. IBC employees will continue to process claims but will be using Highmark's systems instead of IBC systems. IBC and Highmark remain separate and independent companies. We are committed to working closely with our network physicians and hospitals to provide continued information, support, and necessary training. In order to keep you informed of the upcoming changes, we will be sending an increased volume of communications. We have also created this new section within Partners in Health Update ^SM ? Business Transformation ? which will be dedicated to news related to this transition. We ask that you read each edition carefully as we will outline any changes that may affect your day-to-day operations. Additional communication channels will include direct mail, the NaviNet^? web portal, our website, emails, and face-to-face provider education. As noted earlier this year, we have already begun to engage and educate trading partners and clearinghouses on the upcoming EDI changes. Please be sure to check with your third-party vendors to see if changes to your current processes are necessary. We will provide comprehensive communications and tools to support our members and providers before, during, and after the migration to the Highmark operating platform. If you have questions related to the transition, please email us at provider_communications@ibx.com.
