What is organization/medical group affiliation?

Physicians and other care providers are often part of companies or organizations; you may want to search only for providers within a particular company or group. Examples of organizations or medical groups include Group Health Cooperative, University of Washington Physicians, Virginia Mason, and Swedish Health Services. If you do not know the complete or official name of the organization, you can type in just one or two keys words, such as "Group Health," "University of Washington," or "Swedish."
