    I am unsure what to think about the actual time I had face to face with my doctor. This was a six month follow up and I actually spent less than five minutes interacting with my doctor. For the amount of money I see that you charge my insurance company for this visit, I consider the charges extravagant compared to the actual minutes I was face to face with my physician.
