I first saw Dr. Han in 2002 and was relatively happy with my results. The problem arose afterwards, as Dr. Han had required that I complete a deep cleaning before having my cavities filled. Though he claimed it was a necessary procedure, my insurance claimed it was not and would not cover the bill. The insurance asked Dr. Han to submit a report as to why it was necessary, which he never submitted though I asked him repeatedly. The end result was a $700 bill coming from his office nearly 3 years later when I had assumed everything had been resolved. Though the doctor ended up discounting some of my bill, i was still forced to pay a large portion out of pocket for what I had assumed would be a routine cavity fill nearly 3 years before.
