Citing the 3.6 million Americans who miss medical appointments each year due to a lack of reliable transportation, Uber is launching Uber Health, a new HIPAA-compliant service that partners Uber's fleet of drivers with hospitals, rehab centers, senior care facilities, physical therapy centers and more. When you book an appointment, a healthcare associate can go ahead and book a ride for you, too, sending you the details and then reminding you again when the driver is on their way to pick you up.

Uber lets healthcare professionals book the ride for you because it wants to keep Uber Health accessible to users who don't own a smartphone, or who aren't familiar with the ride-sharing service to begin with.
