It depends on whether or not the cath was left in after the injection was done. If the cath was removed right after, then 62311 would be correct. If it was left in for continuous infusion or intermittent bolus, then 62319.
For 72275, that can be billed separately, but you would need a complete and separate radiology report to support the epidurography.
Fluoroscopy however doesn't need a separate imaging report as it's just guidance. Billing for the physician is fine, however if you're billing for a facility it may be included in the facility fee, especially common for ASC's, which is where a lot of epidurals are done.
I am kinda surprised that they haven't made fluoro a required component, because I've done some research and according to a lot of studies in 1/3 of all epidurals that do not use flouroscopy, the medication is misplaced...essentially the doctor misses 1 out of every 3 times they don't have some form of guidance. Loss of resistance is great but it's no match for actually seeing where the needle is.
