My thoughts there are that there are a couple of factors at play - false positives, which might lead to interventions, even exploratory, that are not zero-risk. Even without risk, not zero-cost. And as such you end up with "you had no symptoms or concerns about condition X until you had this not-recommended MRI, and then treatment was ordered about condition X that was actually a false positive". Insurance doesn't view full body MRIs as medically necessary preventative screenings and this is generally accurate (though I'm also not naive enough to believe that a non-insignificant part of their objection might be cost).

Do you have an example in mind for this? Non-zero risk interventions are pretty rare if only one signal is present. If that signal was deemed worthy to result in a non-zero risk intervention, then you're completely ignoring the risk associated with ignoring that signal, which is what justified that non-zero intervention!

> Insurance doesn't view

This suggests a very fundamental misunderstanding of healthcare, treatments, and what insurance companies exist for. They are not about health policy or well being. They are about derisking profit loss. Their recommendations are to reduce cost, and nothing more. Doctors understand this, and will tell you this very plainly, as you fight to get required treatments covered.

Doctors understand this, and will tell you this very plainly, as you fight to get required treatments covered. I am someone who has worked for providers, worked as a paramedic, and worked for a company whose customers were health insurers, as we built claim benefits management systems for them, so literally the logic to calculate deductibles, handle accumulators, provider negotiated rates. The issue is not my misunderstanding, it is that "health insurance" in the US is the worst of all worlds - health insurance when convenient (to the insurer), amortized healthcare when convenient. It used to be that about the biggest offering that health insurers could give you was better provider-negotiated rates, but that era is largely behind us with the vertical integration of supply chains, and a health insurance industry that can only make more money when prices go up (if your profits for premium administration are capped at 15%, the only way that number goes up is if premiums go up, because healthcare costs more - this is compounded by the fact that it's in everyone in the system's interests for it to cost more except the actual consumer). Everything has had to be fought for - otherwise, to your point, why are actual clinical "annual exams"/"wellness" visits covered at zero cost, but incentives for weight loss (as in obesity reduction, even pre GLP-1s) or cardiac health are near zero while a gastric bypass is covered in toto.

		> Do you have an example in mind for this? Liver lesions, often benign cysts. Other cysts too (kidney, ovarian). Will often require targeted contrast MRI, and needle biopsy - which has notable risks for bleeding, often minor, but 3-4% can require surgery or even transfusion. Bile leakage or infection can also result, or injuries to the gallbladder, bowel, bile ducts.
