Hello all! I have just started a medical billing company and I bill for 5 providers. Before I get too deep into it, I want to make sure I am doing everything correctly. How can I get access to all the insurance carriers websites. So far, the clients have just given me their usernames and passwords. I am wondering if the insurances require billing companies to sign up themselves and be given the username and password or if it is ok to use the clients information. All the information you can give me about this would be great. Thanks so much!
