While this may make sense from the perspective of why people get insurance (to mitigate a catastrophic loss), it doesn't consider the insurer's incentives. No insurance company will want to underwrite a plan that doesn't bundle routine services, since those clearly reduce risk of complications down the road. A yearly checkup is cheap compared to missing a disease and letting it get worse.
> No insurance company will want to underwrite a plan that doesn't bundle routine services, since those clearly reduce risk of complications down the road But current plans don't require you to get routine services like an annual physical; they just cover them if you get them. That doesn't make sense if the insurer's incentives that you describe are driving the plan. Also, these incentives don't seem to be operating…
Car insurance doesn’t cover routine maintenance because they also don’t cover problems that arise from not getting routine maintenance. I’d you neglect oil changes and blow up your engine, they don’t care, they don’t have to pay for it.
