The most important thing I have learned about filling out a clam form is not to forget anything. You need to make sure that you have everything filled out the way it is supposed to be. Without having everything filled out the right way, the hospital or doctor might not get paid for the services they provided. There are many steps in filling out the forms you need. The first one is to always make sure that you have the right patient's chart when filling the forms out. You also need to make sure that you are only filling in the parts that are needed. If you fill out the other parts you could confuse the insurance company. If the for comes back because you forgot to fill out something that is just farther back the payment gets pushed and more money the hospital or doctor loses. You need to make sure you have all the right information and a signature on file for you to be able to send the form in. Without the signature on file then you legally can not send the form.
