I think there is a pretty obvious spin against traditional FFS payments in this article. Most physicians remain in private practice, and if you are employed, who ever is paying you will get payed mostly by FFS reimbursement. RVU is essential just FFS for employed doctors. The other models are not really beneficial to treating physicians, they will provide more hoops to jump through and road blocks to getting paid for seeing patients.
I like to call "fee for service" "paid to see patients," while other models I would call "paid to jump through hoops."
