represent approximately 95%, 3% and 2%, respectively. Together, all operating segments are aggregated into a single reportable segment in our consolidated financial statements based on similar services provided, service delivery process involved, target customers, and similar economic characteristics.
Across our operating segments, we offer a diverse and comprehensive array of occupational health services, including workers’ compensation, employer services and consumer health services:
•
Workers’ compensation services include the support of workers’ compensation injury and physical rehabilitation care.
•
Employer Services consist of drug and alcohol screenings, physical examinations and evaluations, clinical testing, and preventive care, as well as direct-to-employer services that include the services described above and advanced primary care at our onsite health clinics.
•
Consumer Health Services consist of the support of patient-directed urgent care treatment of injuries and illnesses.

We partner with approximately 200,000 employers, including 100% of the Fortune 100 and approximately 95% of the Fortune 500, as of December 31, 2023. Since 2015, we have supported the treatment of approximately 6 million occupational injuries. We currently estimate that we supported the treatment of one in every five workplace injuries in the United States for the year ended December 31, 2022 (based on the latest data from the U.S. Bureau of Labor Statistics). In the United States, 65% of employer locations are within approximately 12 miles of one of our occupational health centers and we have occupational health centers in over 80 of the 100 largest Metropolitan Statistical Areas, as of December 31, 2023. Our services are used by employers across industries, including transportation, distribution and warehousing, manufacturing, construction, healthcare, and municipal government services, among many others. Utilization is driven by occupations that have historically posed a higher-than-average risk of workplace injury and illness.
We retain and expand existing relationships and attract new employers through demonstrated performance of clinical outcomes and patient satisfaction. We believe our success is substantially due to the structures and processes that we have developed with the aim of delivering consistent and high- quality care, which we believe creates a key competitive advantage for us. See “— Workers’ Compensation Services — Injury Care”. Guided by our mission to improve the health of America’s workforce, we provide care that supports the delivery of improved health outcomes, reduced employees’ days away from work, and lower workers’ compensation costs.
We ascribe to the philosophy that injured employees recover better through early intervention and a quick return to normal activities. Our methodology focuses on increasing function to expedite the employee’s safe and sustainable return to work, helping lower medical and indemnity claims costs incurred by employers. See “— Workers’ Compensation Services”. In 2023, about 95% of injured employees seen by us after their initial visit were recommended for return to work in some capacity on the same day according to our internal data. Additionally, results from workers’ compensation claim studies we conducted show a 25% lower average in total claims costs and 61 fewer days per claim when using our occupational health centers instead of non-Concentra health centers.
