U.S. Physician Groups Market To Reach $691.0 Billion By 2033

U.S. Physician Groups Market Growth & Trends

The U.S. physician groups market size is expected to reach USD 691.0 billion by 2033, registering a CAGR of 7.9% from 2026 to 2033, according to a new report by Grand View Research, Inc. This growth can be attributed to the shift of practitioners from solo practices to group practices. In a group practice, a physician has the capacity to manage advanced, essential, and expensive medical equipment. Group practices can expand their reach to cover a broader geographic area, operate across multiple locations, serve a larger patient base, and achieve greater profitability. In addition, practitioners can receive valuable feedback and insights from colleagues and co-workers when working within a group.

In the U.S. market for physician groups, value-added services encompass various offerings beyond traditional medical care, such as telemedicine, chronic disease management programs, patient education resources, wellness programs, and preventive care initiatives. By offering these services, physician groups differentiate themselves in the market, attract new patients, and improve patient outcomes. For instance, in August 2023, The Northwestern Medical Group launched the Northwestern Medicine Canning Thoracic Institute Hispanic Program, offering personalized care to Hispanic patients in their native language.

The growing government initiatives to promote physicians' revenue in the U.S. are expected to propel the market's growth over the forecast period. Government bodies have realized the importance of physicians in developing a value-based healthcare system in the U.S. and have undertaken various initiatives to bridge these gaps between revenues of different specialties. For instance, in January 2024, Commons Clinic, a value-based physician group offering musculoskeletal care to patients in Los Angeles, launched the Center for Spine Economics, Outcomes, & Research with plans to invest USD 100 million over the next decade. The center aims to test and research new models that move spinal care into community-based accountable care networks and out to hospitals.
