physician IV coding

Is there only one initial IV infusion code used for physician infusions 96365 and 96374? The only time I know to code another initial infusion is if there are 2 sites infused such as rt arm and lt arm as sites. This is not facility coding. thanks for any help!!
ie: IV push 2 pm drug A
IV push 6pm drug A again

Do you just code 1 initial and total drugs? We cannot code 96376 (facility only code)
