That said, if they don't bill the VA and sends you a bill, call them and tell them they have to bill the VA. If they tell you that you have to pay and then they will bill the VA and send you your money back, tell them that is against federal law. I have no idea if that is true or not, but most companies do not want to take a chance. Of course, there is one company out there that won't, Alcoa Billing Center, but every time I get a bill from them I call them and tell them they have to bill the VA. I write down the name of the person I spoke to, date and time. Sometimes it can take a year but they finally do it. Now if a company sends a bill and the VA denies it you have to appeal. Write down why you went to the hospital. They will deny the claim. Now you write to them and tell them you are appealing and insist that they give your claim to a doctor who specializes in why you went to the hospital. I can't tell you what happens when you speak to the doctor since in about the 12 times this has happened I never spoke to their doctor and every claim I made was approved. It can take time, but in the 24 years I have been using the VA, I have never had to pay. One other thing. If the VA pays a claim you should get a monthly letter showing all payments made that month. The reason for you to keep them is in the past I have received the letter showing who was paid but later will receive a letter from another company that did something different but was not paid. I send them a copy of the VA letter showing them that they should be paid also. If anyone else has any ideas on this please post it.
