KHE is probably right that cataract surgeries will still be done. I envision doctors will try to make-up the cost by upselling the premium lens, pushing other surgeries such as blephs/ptosis, fillers/botox.
In the end, it'll be the more ethical docs who'll hurt the most.
Believe me, you won't "make up" the difference with blepharoplasty. Those would be cut by the same amount, and many patients don't have the money to pay a typical cosmetic fee. Everyone wants it done for the Medicare/insurance "fee."
Sure, you could try to up-sell premium IOLs, but most cataract surgeons are already doing that. I doubt the conversion rate would really work to bring in enough to cover the losses. You should assume a busy practice without any more significant capacity to expand.
Cataract is one of the highest payments for time in ophthalmology. Uncomplicated cases are under 20 minutes of OR time and frequently less than half that in very efficient settings. A carefully done blepharoplasty needs an hour, especially if you are combining it with levator advancement.
So you earn $680. Now that becomes $480. Overhead originally at 50%, or $340, not including any pay for the doctor. So instead of receiving $340 for the surgery and all the followup care--let's say three office visits with a refraction in a non-comanagement model, the doctor gets $140. If insurers follow, that is what everyone pays. Aren't you glad you worked so hard to become an ophthalmologist?
Surgery becomes a relative money loser, especially when you consider the relative liability risks.
There is no working around this with premium IOL and cosmetic surgery. Those veins are already mined, you don't get more of that just because now you want more.
It would be impossible to start a viable new practice with that kind of payment. KHE, even if you think business would continue as usual, banks would know better. The failure risk would make business lending to ophthalmologists very difficult.
Insurers cannot just impose lower payments and expect to retain a functioning and healthy private care industry. On top of that, their initiatives are costly. This would devastate private practice. Scaling up to big groups will not save you either, they are laden with disproportionally greater costs in management. Practices have already been working more efficiently, there are no more significant opportunities to cut, and in fact many will have to deal with substantial new costs for electronic records, the majority costs of which will be borne by the practices. Also, most of the practices that have implemented EMR are now realizing that ongoing costs are very substantial with software upgrades, vendor's maintenance fees and a relatively short replacement cycle needed for computing equipment.
KHE, doctors will likely continue to do surgery, but you will see widespread abandonment of Medicare participation along with private contracts that seek to follow Medicare. Ophthalmology will likely return to a pre-Part B practice model, similar to the way dentistry is practiced. (In many places, a dental crown costs $1500, so what should a cataract surgery cost?)
