Obamacare / Affordable Care Act : classic or dud?

it could be something as dumb as your doc office coding something the wrong way causing claim to be denied, but see it's really fun to just blame insurance co's for everything wrong with our fucked up system

example of backasswards way we do things:
I'm advised to have colonoscopies every few years due to Crohn's. If I do, it's coded as "preventative" and isn't covered by insurance. So one might choose to forego regular screenings. Then, things that can be addressed at early stages progress, and now I'm needing to get admitted to a hospital, which will most likely order a colonoscopy anyway except now it's coded as "diagnostic" and is covered by insurance. But obv now the ins co has to pay out $$$ for my hospitalization, in addition to the diagnostic colonoscopy! And I'm in poorer health. Lose-lose situation.

In a move last month that received little fanfare, the Biden administration finalized a rule that would give states the option of adding adult dental insurance coverage as part of their Affordable Care Act plans...

Under Biden's rule, states have until 2025 to decide whether to mandate that insurers cover dental benefits for adults. The dental benefits would not take effect until 2027. No states have publicly signaled yet that they intend to require ACA dental benefits in 2027, however, advocates say the new rule could represent a significant expansion of dental insurance, which gets less scrutiny than medical insurance for hospital, doctor and pharmacy bills.
