CPB (Certified Professional Biller) Certification Practice Exam

The correct choice is indeed Blue Cross Blue Shield (BCBS). BCBS operates as a federation of independent health insurance companies that are licensed to provide health insurance under the Blue Cross and Blue Shield names. These companies managed to share resources like buildings and computer services to streamline operations and reduce costs while maintaining distinct corporate identities. This collaboration exemplifies how allied companies can function in a joint venture setup to maximize efficiency while preserving their unique brand and operational frameworks.

The other entities listed, such as Anthem, UnitedHealth Group, and Kaiser Permanente, operate as distinct health insurance providers with their own business models and identities, and do not represent a joint venture of the nature described in the question.
