Comcast has signed on as a client of San Francisco-based Doctor On Demand in order to provide its employees video visits with the healthcare service’s doctors.

Comcast plans on integrating Doctor On Demand into its health and wellness offerings and will, for certain plans, fully subsidize employees’ video visits with Doctor On Demand physicians. The service matches patient requests with licensed doctors in their areas.

Using Doctor On Demand, Comcast employees will be able to receive medical care from their homes and offices.

“With the rising expenses and continual changes in the U.S. healthcare system today, we are always looking at new ways to offer our employees the highest quality care at an affordable cost,” said Shawn Leavitt, senior vice president of global benefits for Comcast and NBCUniversal. “Inconvenient and expensive urgent care visits are common choices for health treatment because employees often don’t know where else to go for everyday care.

“By using Doctor On Demand’s technology and making it available on computers and smartphones, our employees will have immediate and convenient access to thousands of board-certified U.S. physicians to diagnose and treat issues from the common cold to sports injuries.”

Doctor On Demand, which was co-founded by Dr. Phil McGraw’s son Jay McGraw, among others, also announced it had raised $21 million in a round of funding that was led by Venrock and joined by Shasta Ventures and Virgin Media founder Richard Branson. As part of this funding round, Bryan Roberts, partner at Venrock, joined the company’s board.

The company also announced that patients could now conduct video visits with physicians on their desktop computers.

Doctor On Demand is available in 46 states across the country. Patients can download the Doctor On Demand app on a smartphone or tablet, or by going to the company’s website on their desktop computers.

Doctor On Demand physicians use video visits to diagnose, treat and write prescriptions for patients when clinically appropriate.
