The real damage was done at the beginning of this year, when lumbar ESI was cut 50% and cervical ESI cut 60%. Although they're bundling the fluoro, they've reversed some of those cuts, so the net impact is increased payment for ESI's done in the office setting compared to this year (but still a big cut compared to 2013).
For those who do injections in ASC's or HOPD, payment is cut further. Note that none of this applies to transforaminal epidurals, for which fluoro has been bundled for several years now.
Money is the worst reason to specialize in pain these days.
