If ACA goes away, I think health insurance will revert to how it was prior to ACA.
A health insurance company would be irresponsible to it's shareholders to accept any and all that applied as the cost of cancer for example is pretty steep.
So, anyone with a pre-existing condition (or presumably, anyone who gets a new condition while covered under a non-group plan) should be denied coverage for future years to save shareholders $?
I used to thing this way, until about five years ago, when I started to get shots in my eye which cost $18K per year. Without the shots, I'd be blind in one eye. As it is, I'm still w@rking, and a productive member of society. We need to address why a single shot costs $3,300.... I partly blame the Medicare/Medicaid reimbursement procedures for the high cost of health care here per person, rather than just the insurance companies.
When the whole epi pen thing was on the news, they showed the Medicare reimbursement formulas for the epi pen. Ridiculously complicated, and for a drug that's been out as long as epinepherin and that's as cheap to make, it was obvious that we (the taxpayers) are overpaying. Just ask those seniors who travel to Canada to buy their prescription drugs!
One more example...for a physical therapist to drive one mile to a care facility, and give one hour of PT to my mom, Medicare reimbursed something like $600. I'm pretty sure the therapist wasn't pulling in 2,000 hours x $600, or $1,200,000 per year in salary and benefits. That's seriously messed up!
Unfortunately, no one in Congress wants to reform or limit the cost of health care. This should be the first step of health care reform.
