Physician groups are organizations formed by doctors who come together to provide medical care and services. These groups can vary in size and structure, ranging from small practices with a few physicians to large networks that include many specialists. They often collaborate to improve patient care, share resources, and streamline administrative tasks. These groups may operate independently or be affiliated with hospitals and health systems. By working together, physician groups can enhance their bargaining power with insurance companies and improve access to care for patients. They also focus on quality improvement and may participate in value-based care initiatives.
