Went to a doctor in this group for about 2 years. He wanted a lab report and I went to have it filled as he asked. About 4 months ago I received a bill from the lab stating that I owed over $500.- for the doctor's lab results. I called his office and spoke to his MA. She told me that the wrong codes were entered and to dispose of the bill. I received a second bill and recalled the office to speak to the account manager. I called twice and left 2 messages to which she never returned my call. I called the office manager and again, left a message to NO return call. I then went to the doctor and hand delivered him a letter stating that I am on a fixed income and not responsible for his entering the wrong codes- NO response. I find these errors very unprofessional, by both the staff and doctor. I wrote to the Arizona Medical Board with a grievance and in the interim, I paid for the bill to the lab. POOR POOR POOR! Stay away from this organization!
