Injections done in office vs ASC

I have a Pain Management provider that will start doing his injections, ESI, Nerve blocks, RFA's in office rather than at the ASC. He is purchasing a Fluoroscopy machine as well. I'm unfamiliar as to what else we can bill on top of the injections (eg: 64493, 99144)? Are we able to bill for supplies used?

If anyone can provide any help it would be GREATLY appreciated!!
