Honest question as someone fairly new to the field... right now, the technical reimbursement for IMRT is about twice that of 3D. Was the ratio the same in the golden era of IMRT?
It's definitely not 2:1 in freestanding these days with all the IMRT code bundling. It's getting closer and closer to a wash. IMRT treamtent code + prof IGRT is barely more than 3D treatment code + prof/tech IGRT. (I did the calc in a random geography and the difference is $40/day globally). Also, some of the per field calc and sim codes you get with 3D are bundled into the IMRT planning codes which negates the big difference in the IMRT vs. 3D plan code.
Also, regarding the difference back in the "golden era," the ratio was highly geographically-dependent (vs. now where the differences are minor), but definitely not 10:1 freestanding. You can actually go to the medicare website and look up historical reimbursement for old XRT codes. In the 2000's it looks like IMRT treatment code ranged from 600-1000 per fraction vs 3D which seemed to range 200-300ish. Several of my older colleagues quote 50k as the high end of reimbursement for prostate IMRT "back in the day."
