While Congress may be hotly engaged in whether to repeal and replace the Affordable Care Act, health care industry executives are split on whether the debate is affecting their business — as market forces may be having a greater impact, according to a new survey by WEX Health, a health care financial technology platform provider headquartered in Fargo, N.D.

Hundreds of executives from health plans, banks and administrators attended WEX Health's Partner Conference in Hollywood, Fla. and were asked about the current situation in Washington, D.C. regarding health care reform, and 35 percent said it was positively affecting their business, while 18 percent said it was negatively affecting their business. However, nearly half — 47 percent — said it was not having any impact.

"It's important to note that the tailwind of market forces are impacting their business more so than what's going on in D.C., as we continue to see moves toward consumerism and consumer-directed health care," Ryan VanOverbeke, WEX Health's vice president, health care partner executive, said in an interview Tuesday.
