Health plans like hospitals that provide care efficiently.
So, if patients with certain health problems are far from these medical centers, more insurance policies are offering to cover the travel costs.
"When you do a good job of taking care of people … you typically also end up paying less for their care," said Dr. Richard Migliori, chief medical officer for Minnetonka-based UnitedHealth Group, the nation's largest health insurer. "There's a quality dividend."
Travel benefits are part of "centers of excellence" programs. They've been around for decades, but interest seems to be growing again as employers and insurers try to contain health care costs.
Some hospitals and doctors are wary of the trend, though.
Medical centers should be recognized as superior when they truly deliver higher-value care, said Dr. Donald Jacobs, president of the Minnesota Medical Association. But there are suspicions that insurance company programs are driven primarily by cost, not quality.
"You run the risk of driving patients away from really good providers … based on what I'll call the marketing concept of excellence, as opposed to the measurable difference," Jacobs said.
There aren't numbers that track exactly how many patients are crossing state lines as part of centers of excellence programs.
