Video consultation app Doctor on Demand has launched and already raised a $3 million seed round from Venrock, Andreessen Horowitz, Google Ventures, Lerer Ventures, Shasta Ventures and Athena Health CEO Jonathan Bush.

The app offers patients a portal from which to connect to physicians and is available on iOS and Android platforms. Each video call, which costs $40, can be paid for with a credit card, a health care spending account, or flexible spending account, and the service is available in 15 states: California, Florida, Georgia, Illinois, Indiana, Michigan, Mississippi, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington.

Patients are encouraged to use the app for "non-emergent clinical issues" that do not require imaging services, such as common colds, rashes, eye problems, common prescription refill requests and muscle or sport injuries.

Doctor on Demand's high profile team of cofounders includes CEO Adam Jackson, former White House fellow Dr. Pat Basu and Emmy Award-winning executive producer of The Doctors Jay McGraw, whose dad is TV's Dr. Phil. Former senator Tom Daschle, and Athena Health's Jonathan Bush also serve on the company's board.

In October, American Well launched a similar service for consumers. Also available on iOS and Android, American Well's video visit service is available in 44 states and costs $49.
