They care about prevention but only if it's very cheap. I get emails all the time from my insurance company about joining their program that is supposed to help you live a healthier lifestyle.
I started getting emails from Cigna about Omada after switching over to them last year. They pitch it as something you can sign up for to get health coaching. They (or their AI, soon if not already) provide that by sending you some "free" sensors (scale, pedometer, etc) and collecting lots of health information.
Searching the web shows that Cigna forces some patients to use this program in order to receive coverage for certain conditions. They're likely saving all the info collected through it in order to use it to deny you coverage if they can at all make an argument that something was caused by your lifestyle, was pre-existing for a certain amount of time, etc-- at least, that's the vibe I got from researching it.
