Walmart, the world’s largest retailer, is moving deeper into the primary care and mental health market, opening a new clinic called Walmart Health in Georgia. The company recently updated its website with a link to Walmart Health and also went online with the site “Walmarthealth.com,” where patients can set up appointments. Walmart is testing the concept with this initial clinic that will give patients access to comprehensive and low-cost primary care, including for mental health issues. The website indicates that the company will offer primary care, dental, counseling, labs, X-rays and audiology, among other services. Walmart is already one of the largest pharmacy companies in the U.S., offering in-store sections for prescription drugs in almost all of its 4,700 locations across the U.S. The company said health and wellness, which includes pharmacy, clinical and optical services, accounted for about 9%, or $36 billion, of its roughly $332 billion in U.S. sales last fiscal year. Walmart’s distinct opportunity is that roughly 140 million people visit its stores every week, and it has about 1.5 million U.S. employees spread across cities of all sizes, including in rural areas where there’s a shortage of health-care services.
