Walmart is closing its health centers and virtual care service after struggling to find success with the offerings, the U.S. retailer said Tuesday.

The company has three clinics in Orlando, two in Kissimmee, and one each in Ocoee, Sanford and Winter Garden, according to its website.

The Bentonville, Arkansas-based company said that after managing the facilities it launched in 2019 and expanding its telehealth program, it concluded “there is not a sustainable business model for us to continue.”

Walmart had 51 health centers in five states, with the goal of helping people save money on their health care needs.

“This is a difficult decision, and like others, the challenging reimbursement environment and escalating operating costs create a lack of profitability that make the care business unsustainable for us at this time,” the company said in a statement.

A spokeswoman said reimbursement proved challenging “from all types of insurance.”

Walmart does not yet have specific dates for when its health centers will close, but said that it will share that information when it’s available. The company said that employees working at its health centers are eligible to transfer to any other Walmart or Sam’s Club location.

Walmart still runs almost 4,600 pharmacies and more than 3,000 vision centers in the U.S.
