I did a little of my own digging because I do mental health too and many MH provider's don't want their address sent.. USUALLY when you credential most of the carriers require an actual physical address anyway, and even though it's required for 2010 transactions, the carriers will still send payments and remittances to the address they have on file, with that in mind, I'm pretty sure patient's won't see the physical address at all and that would be the only thing providers would need to be concerned with.. but again, they had to provide a physical address for credentialing purposes, so this really shouldn't be a big deal.
