We have a mental health provider who is going to start "seeing" patients on a Skype. I want to make sure I bill correctly and legally. I have been told that as long as the service is a face to face, using Skype, and the encounter is documented as such, that I would use the usual E/M codes for the encounter. Is that correct? And, is there some kind of modifier to indicate that the encounter was telemedicine vs. the usual face to face in a clinical setting?
