A most efficient insurance program would be a closed loop.
Any leftover money not spent on care would be used to reduce premiums the following year and/or be saved for higher claim years.
I wonder how that could exist in the US? Perhaps these health sharing ministries are as close as we'll get: https://www.medishare.com/
However, I don't think the problem is truly fixable without Medicare for all or similar single payer scheme. There is just a huge gap in not just bargaining power but just knowledge of the market information between the seller (hospitals and health care providers) and the buyers (sick people) that a free market solution can't even work in theory. Even if you ignore the fact that I can't exactly shop around when I have an emergency any more than I can shop around when my house is on fire. The only viable solution is single payer and the sooner we get there, the better for everyone.

Commercial insurers are already required to rebate premiums if their medical loss ratio is below the limit.

I understand regulation plays a good role in that, but I can’t believe that it is the only reason..
Huge feature lists, high standards for correctness, strict regulations, existing long-term contracts.
It's like the space industry before SpaceX. Everyone knows the incumbent is inefficient, but you can't compete without building the whole damn rocket.
I think a substantial part comes from low risk tolerance and opting for high quality low volume care
Providers are not the problem here.
much higher profit margins
That is an entirely worthless metric. Pharma and for-profit hospitals benefit from the insurance companies' perverse incentives to keep costs high. Higher cost for care means that the insurance companies can jack up the premiums to maintain their legally allowable margin. A 20% slice of a bigger pie is a larger amount than a 20% slice of a smaller pie after all.Even better, insurance companies can wag their fingers at the doctors and all of Ayn's acolytes will chime in about how for-profit care is here to save humanity from the evils of doctors. All the while the for-profit insurance companies are laughing to the bank because they're disincentivized from negotiating more reasonable prices. There's a reason Medicare pays conversion factors that are about a third to a half of what for-profit insurance companies are willing to pay.
Even better, insurance companies have a captive audience. While the federal mandate to redirect your money to for-profit insurance was struck down, five states (and DC) have their own individual mandates.
They aren't. Since their profits are capped at 20%, reducing costs means reducing profit as well, so they are actually incentivised to keep costs high.
> their claims process is so arduous that providers demand higher rates to deal with the high rate of denials and ever changing minutiae.
I think this is also the case
Why would they turn productivity improvements into lower costs, when they could instead turn them into higher profits? Big health insurers such as UHC practice "intercompany eliminations", as it's known; they own those providers you mention and use increasing charges there to get around the limits on how much of the insurance premiums they can keep for themselves. It's in their interests for the charges to go up, especially on anything that's actually cheap. Productivity improvements is just more profit to launder through the providers they own for the purpose of laundering those premiums.
