Office-based physicians and group practices

There are approximately 230,187 physician practices in the United States.[5] Among these physician practices, 52.8% consist of only one office-based physician.

Physician group practices with 2-5 physicians make up 37.1% of physician offices in the United States. 6.3% consist of 6-9 physicians and the remaining 3.7% consist of 10 or more physicians. In recent years, many small or solo practitioners have come (or are considering coming) together to form larger same (or multi) specialty groups in order to get a leg up on managed care.
