Those are not required procedures, so obviously there is much more of a chance for a real market there. But you can't just compare that with e.g. ER or cancer treatment.
Because the idea that cancer treatment as well as other exotic treatments needing to be covered by insurance is a pile of horse manure - i'm saying it as someone whose grandmother died from cancer and someone who has a few friends that successful beat down cancer.
Lets engage in an intellectual exercise. 10MM USD (today) and for 1 person cancer is gone. Should we include coverage for cancer into all policies?
Your lifetime odds for cancer are like 50%. If insurance doesn't cover life threatening illnesses and life-saving treatments, what's the point in paying for insurance?
I agree it should cover them (in theory). I would even agree that healthcare should be a human right. But even under a zero profit model, for the cases where the treatment is so expensive, what would the financials look like for all the insurance payers? Is it actually even possible?
