We don't have PaySpan, but Medicare REQUIRED us to sign up for electronic payments. I was TERRIFIED to do it. What if they empty our bank account? What if they....what if they...? I hate the thought of giving the government access to my bank account. However, 3 years later, it's been fine. My clearing house sends me the EOB once the money gets sent and it shows up on my bank statement. The EFT comes ON TIME 14 days after I e-claim the claims. (A day later if there's a holiday).
Most of our insurance companies want us to sign up for EFT as well, I'm still hesitant, but Medicare has worked well.
