Yes, invisible diseases are not easy to explain.
I am able to buy cheap HMO dental that covers exam/cleaning 100% , but only certain offices take it. The dentist we love left that office recently and opened a private practice and only takes PPO insurance, so we are sad about that. We aren't even on Medicare, but we are retired and on fixed income, so we can't have it all.
It is exhausting dealing with all these bureaucracies!
