Walmart unveiled its first health center in 2019, offering a variety of services that include primary care, lab, X-Ray, EKG, counseling, dental, optical, hearing and community health. All pricing is low (naturally) and transparent (unnaturally). Walmart is now expanding their model across several sites, with a lot more to go (given that they have 5,000 stores nationwide).
Walmart is not limiting its efforts to in store services. They also just announced their acquisition of MeMD, a leader in telehealth (also known as virtual health).
Finally, don’t forget that Walmart, as with a few other major pharmacy retailers, provide a large list of $4 drugs.
