According to a memo sent to employees, Mr. Setzer is leaving the role to pursue an opportunity in his hometown.
Kyle Kinnard, who is the senior vice president of the neighborhood markets division in the U.S. for Walmart, will replace Mr. Setzer.
The news comes after Walmart Health shared in late April that it was closing all 51 of its health centers across five states and shutting down its Walmart Health Virtual Care services.
