We paid all costs and had a zero balance on the two visits to this Dr for my husband. You have no choice - the dr's policy is to pay on the spot before agreeing to the procedure. We just received a letter that stated: Oct 2, 2012 - During recent extensive research we have discovered some problems with our computer software in reference to accounts with a balance due from patients. Some accounts may not have generated a statement for a number of years. Your accounts seem to have been one of those. Please find enclosed statement reflecting the current balance on your account. While we understand that this is unexpected news for you, the balance is still owed and payment should be rendered upon receipt of this letter. If you are unable to pay the balance in full now, please contact me immediately at 757-838-3975. Otherwise, we shall have no choice but to turn your account over to our collections attorney, at which point 40% will be added to the unpaid balance and your credit will be compromised for seven to ten years. Please do not make this step necessary. Sincerely, Dr Jack Mrazik DDS. My husband met with the Dr's staff today and they say we must pay this balance of over $400. This is unfair-his computer had the glitch!
