I agree with Fred B. Dr. Fishman is caring and conscientious. I would not hesitate to recommend him to my friends in need of an exceptional gastroenterologist. However, his billing staff leaves a lot to be desired. Although I provided them with my Medicare information, they submitted a claim to my old insurance company which I discovered when I received an explanation of benefits from them. I contacted the business office and was told that it would be properly submitted. Last week I received another EOB. I called the business office again and was told that they did not submit the claim to my old insurance that Medicare had done it even though the EOB says it was submitted by Dr. Fishman's office. I contacted Medicare and my supplemental insurance. Both reps advised me that they had no way of knowing my previous insurance. After that phone call, I called the business office explaining what I was told and what the business office had told me. I asked for a call from a supervisor as I was lied to about this claim. I received a message from the office manager stating that the issue was resolved and the claim was submitted properly. However, when I left messages to speak to her, I received calls from the business office who would not connect me with the office manager, felt that I was not lied to, made excuses by stating that they had new employees and that I should've been satisfied that the issue was corrected. She also stated that she had been in medical billing for 20 years. I am an intelligent person and know when there is a training issue. I should have been able to talk with the office manager when requested. If this is the way patients with a billing issue are treated, I would be unwilling to refer them to Denver Digestive. read more
