It sounds fairly reasonable to me to have to pay to get a second opinion for a negative finding on a screening. (That's off-axis from whether an AI should be able to provide the initial negative finding.)
If we don't allow this, I think we're more likely to find that the initial screening will be denied as not medically indicated than we are to find insurance companies covering two screenings when the first is negative. And I think we're better off with the increased routine screenings for a lot of conditions.
