 We just really needed to increase access for our patients so that they can access care when it's convenient for them, not just within office hours, necessarily 8 to 5. And so this is a 24-hour-a-day service, so somebody will respond to you within 60 minutes no matter what time of the day it is. So it's a pretty cost-effective service for patients, and I think that that's something that patients really like, too. The cost of each visit is $30. It's a flat fee. If you end up getting referred out and we're not able to address your problem in the visit, there's no charge for the visit.
