Stay away! They are fraud.
I am very disappointed in there billing practices. I asked them for all costs involved in a doctors visit. I informed them of the fact that my insurance wasnt going to pay at the time of the appointment. I paid the amount they told and then they sent me another bill for additional $100 when I refused to pay it they sent me to collections. They ended up contacting me but I wasnt satisfied with the outcome. As a small business owner when I am not clear or make a mistake on costs I eat the additional costs. If you expect the customer to cover it or go to collections you dont deserve a positive review.
