Walmart is closing its 51 health centers and virtual care service due to financial challenges and difficulties with insurance reimbursement. This decision follows their earlier plans to open more health centers in other cities. Other retailers, such as Walgreens, have also announced closures of their primary care clinics. The shortage of primary care doctors in the US makes it difficult for companies like Walmart to sustain their clinics. The company still operates numerous pharmacies and vision centers in the US.
