The most expensive healthcare surprises are usually the ones nobody saw coming.
IMS's managed care program is built to change that. Before major procedures are approved, our team reviews them for medical necessity, protecting your employees from unnecessary risk and your plan from unnecessary cost.
For members dealing with serious, ongoing conditions, we provide case management support to help coordinate care, reduce complications, and improve outcomes.
Good benefits aren't just reactive, they're preventive. Because a healthier workforce means fewer claim surprises and more predictable costs for your business.

In 1983, Steve Willingham and Joe Clark were working at a folding table with a fax machine, helping businesses in the Texas Panhandle save money on health benefits before most people had ever heard the term "third-party administrator." They weren't following a trend. They saw something that could work for employers and they built it from scratch.
That company is IMS. We're still in Amarillo, still locally owned, and still run by the same principle that guided those first years to take care of people like they're your own. The folding table is gone. The 140-person team and 45,000+ covered lives are not.
A lot of TPAs have come and gone over those four decades. We're not going anywhere.
