Some mega-employers manage clinics on their own while others outsource to clinic vendors or healthcare systems. Many provide clinics within their own facilities, but some offer near-site locations and even share a near-site clinic with other companies. Regardless of which model is preferred, more organizations with 5,000 or more employees are deciding that on-site or near-site clinics can make primary care more convenient and affordable for everyone.

Some of these clinics offer pharmacy services and many have expanded to offer services such as physical therapy, telehealth and even behavioral health. One benefit that clinic operators often emphasize is that by making primary care convenient to employees, and in many cases their family members, fewer employees will neglect primary care because of cost or the inability to take time off to see a doctor.
