The 'ACA' is not one plan and it certainly does not require health insurance carriers to pay for 'ALL' healthcare expenses after you reach your deductible. Coverage varies by state and by level (ie., gold or platinum). Many plans do not cover out-of-network doctor visits for example. On top of this, you need to get prior approval for every medical procedure because not ALL are covered. In some cases, the insurance company will recommend a different treatment, instead of the prescribed treatment. I speak from experience.

AHCA coverage is superior to what we had before, but it isn't enough. It was drafted with the Health Insurance lobby in the room, so do the arithmetic.
