CPB (Certified Professional Biller) Certification Practice Exam

The abbreviation that denotes a system allowing doctors to practice in multiple locations without needing a physical office is "Group Practice Without Walls." This concept refers to a collaborative arrangement among healthcare providers who maintain their separate offices but come together to share resources, information, and services. This system provides greater flexibility, allowing practitioners to focus on their specialty areas and reach patients in various locations without the financial burden of a traditional office setting.

In contrast, General Equivalency Mapping typically pertains to the conversion of codes for healthcare formats and is not related to practice locations. Healthcare Finder is associated with tools or services that help patients locate healthcare providers or facilities rather than indicating a practice arrangement. Health Affairs is a well-known academic journal in health policy but does not represent any system of practice for doctors. This distinction clarifies why "Group Practice Without Walls" is the correct choice in the context of the question regarding practice flexibility.
