My experience was horrible and I will tell you why. I was a patient of Dr. Yi for a couple years and the dentistry was well done, however my complaint is with them not standing behind their promises for billing. In 2014 I went in and explained to the front desk that I was moving jobs from one teamster position to another company (still a teamster at new job) , so I asked the front desk to make triple sure I could still be seen in their office. I also told them with no room for error that I was worried that my insurance would not work there and that I for sure would not want to be seen if that was the case, I even went so far as to set the potential appointment a week out so as to give the staff time to make triple sure that it was okay to be seen. I also let them know more than once I would much rather not be seen than incur a huge bill. This I was assured was alright and they even went as far as to call me on the phone to let me know they had checked and I could come in the day that we had planned. I did not think much about it after that. I had moved from my old address within days of seeing Dr. Yi and had a new phone number ( which I understand made it difficult to reach me and let me know there was an issue), but there was a problem and I was billed over $500.00 dollars and this was sent to collection, which is how I found out 2 years later. At this point I called Dr. Yi's office to find out why after I had asked to please NOT BE SEEN IF THIS WAS GOING TO NOT BE COVERED (several times as I have pointed out), why oh why did you see me if this was even a remote possibility. I was told by staff that this can happen and that they dont have a "crystal ball" to let them know if a claim will be denied and that it can and does happen. So at that point I asked them why did they not tell me that when I asked them (several times)to make sure if I could be seen or dont see me, why oh why did they see me. Also the staff person told me that I would have needed to call the insurance company myself to check on this before hand because all they do is look on the computer to see if the Delta Dental is still active for a person, which would be great if I had not specifically asked them to call to make sure or let me know I MAY NOT BE COVERED. I again asked them "well why did you not tell me that at that time" as I would have made the call myself and found out that I SHOULD NOT HAVE BEEN SEEN. So my complaint is that they did not stand by what they had told me, AND they did not inform me of the simple step I could have taken to avoid this mistake. In the future I will for sure be relaying this story to anyone who will listen and recommending them to avoid this business as well as to let their friends know to do the same. Also I would like to thank Dr Yi and his staff for such a great experience and what came to a $604.00 bill.....THANK YOU read more
