Inpatient DRGs don't pay for technical component since it's all lump sum for diagnoses. Doesn't matter if you order 100 MRIs or 1 xray. Sure, outpatient imaging is still FFS, but I don't think it's anything close to OR fees (unless you have data to suggest otherwise). I used to be part of multispecialty physician owned group who got the TC for all imaging ordered. It honestly wasn't that much after you account for overhead. Medicare pays like $300 TC for a knee MRI which takes 45 minutes. They pay around $12k facility fee for a knee replacement which takes 1-2 hours.
But my overall point is that the landscape is pretty bleak looking at these current numbers. Admin won't cut too many admin, and there's no easy fix to nursing or overall staff shortages. And the recession hasn't even hit yet. Once it does, we'll see payer mix truly deteriorate, along with reduced outpatient volumes. It may soften the labor shortage, but it's in no way going back to pre-covid salaries or availability. My bet is that we may be looking at a post-corporate landscape, and it's unclear which specialties will be in the best position at that point. Make your money now cuz who knows if any money can be made (and by whom) in the not so distant future.
