Just one thing, it's none of my business, but fighting with medical administration and billing is something I've done a lot of over the past 5 months. If you or the pediatrician haven't followed up with Kaiser about the VCUG, you might want to do so rather than waiting for them to call. I don't have personal experience with Kaiser, but I've had a bunch of experiences with crossed wires and orders getting lost or the wrong tests being ordered. My twin mottos are now "question everything," and "I don't wait for you to call me, I'll call you."
