After confirming insurance coverage, my husband saw Dr. Lucas approximately 6 months ago for a routine exam and cleaning. He was very impressed, however there was a problem with the insurance. Because the insurance was taking so long to pay (even after lengthy time spent on the phone and correspondence, both by us and his office), we went ahead and paid ourselves. We are now awaiting our portion of the payment from the insurance company. My husband is now scheduled for cancer surgery so I called to re-schedule his upcoming appointment and to make appointments for the rest of the family (as we did not want to complicate things more until the insurance was straightened out), only to be told we would not be seen unless we pay in advance. Dr. Lucas has chosen to participate with this insurance company of his own free will, so I really do not understand requiring payment in advance. If he has a problem with this insurance company, then he should choose not to participate instead of penalizing his patients. I am currently in the process of letting the insurance company know of this practice. This whole experience has been very disturbing to us. I would advise you to be extremely careful when dealing with this office.
