30 top urgent care center chains

Price and accessibility pressure increases consumer interest in walk-in services.

Urgent care utilization is on the rise

With a push from value-based care, consumers and provider organizations are looking for lower cost approaches for getting care. Urgent care centers continue to be on the fast track for growth, as they report advantages in both the cost of care and the ability to access it quickly. The nation has more than 7,000 urgent care centers, according to the Urgent Care Association of America (UCAOA). While the market is fragmented, there are some major players operating multiple care centers. The use of IT is growing among these centers, as they aim to fit into the care continuum and communicate treatment with other providers in the community.

Here, we list some of the largest operators of centers in the U.S., with help from Merchant Medicine, which regularly reports on growth among care center chains. This listing excludes retail clinics, specifically those that operate within drug stores. Instead, we focus on clinics that operate separately from a retail outlet.
