BENTONVILLE, Ark. — Walmart has hired Ochsner Health executive Dr. David Carmouche to head up Walmart Health.

Dr. Carmouche had been the president of Ochsner Health Network, where he oversaw 2,700 physicians across 34 hospitals, as well as vice president of the New Orleans-based health system’s value-based care and network operations. Business Insider first reported the hire.

Dr. Carmouche helped coordinate a direct contracting agreement between Ochsner Health and Walmart in 2018 that covers about 6,600 Walmart and Sam’s Club associates in Louisiana. Walmart has been steadily expanding its direct contracts with hospitals and physician groups to steer employees to select providers.

He joins the company amid a broad reshuffling of the leadership team overseeing Walmart’s health care business. Marcus Osborne, who previously headed up the Walmart Health clinics, moved into a new position involving healthcare strategy and innovation earlier this year.

The retail giant has also been opening more comprehensive primary care centers inside its stores. These clinics provide chronic disease management, urgent care, mental health counseling, and dental, vision and hearing services. The locations also offer lab services, x-rays and diagnostics via a joint venture with Quest Diagnostics.

Walmart Health, includes about 20 medical clinics in Arkansas, Georgia, and Illinois. It’s set to expand into Florida next year. Walmart is also gearing up to offer telehealth nationwide after acquiring the telehealth company MeMD in June.

The chain also recently teamed with Transcarent, which offers second opinions, medication reviews and referrals to surgery sites and centers of excellence to more than 100 self-insured employers.
