With a share price up 104 percent year to date and a new mobile app that saw 17 million downloads since its release two weeks ago, WebMD appears to have a healthy diagnosis ahead of it.

"We certainly provide a really comprehensive health and wellness experience, so it's not just really around disease and condition, but it's that plus healthy lifestyle, healthy living," CEO David Schlanger said on CNBC's "Fast Money." "We really view health as an everyday activity."

WebMD stock closed at $29.49 per share, down 0.24 percent.

Asked whether the trend toward mobile would eat into WebMD's revenues, Schlanger counted on healthy desktop web traffic. "We actually view mobile as an incremental opportunity for us," he said.

"We have ample page-view inventory on PC to satisfy our current revenue expectations," he said, adding that "very little mobile" revenues represented growth potential.

WebMD could be facing new competition in the online health space from Google, which announced the launch of Calico, "a new company that will focus on health and well-being, in particular the challenge of aging and associated diseases."

Schlanger said that he didn't see the new venture as a true competitor.

"As I understand the Google announcement, it's really not about empowering consumers with health information," he said. "It's actually looking for solutions to health problems via new pharmaceutical products or biotech products.

Schlanger, who counts 125 million visitors a month to WebMD.com, said that another potential catalyst lies in the implementation of the Affordable Care Act, also known as Obamacare.

"We view the Affordable Care Aact and a bunch of the other macro trends that are actually happening in health care as opportunities for us," he said.

Schlanger cited the launch of a new channel, featuring "a comprehensive set of information and services" on the health care law, which he called "very complex legislation."

"From a monetization perspective, it actually creates opportunities for us because for the first time health plans now are going to have to become health-marketing organizations because they'll be selling health insurance directly to consumers," he added.
