Premiums have increased greatly.
Deductibles and co-insurance have increased greatly.
The only hospital in this city is NOT available to those with individual ACA policies, only employer-sponsored traditional plans are accepted there.
"Like your doctor, keep your doctor"? Not if she is fed up with the bureaucracy and can afford to retire. The most experienced GP/family care doctors who do not need to work the longer hours for lower pay are going away, leaving the less experienced ones to see more patients per hour and struggle to get paid by the insurance companies.
Competition between insurance companies is greatly reduced, only a handful remain in the market. The well known, reputable companies are leaving the state exchange, leaving only smaller, weaker companies available for individual ACA clients. As a result, the state insurance exchange is failing, and must increase rates to stave off insolvency.
Mandate for coverage of pre-existing conditions has led to "free-loading," where young healthy persons opt to pay the tax penalty for being uninsured, knowing they can sign up later and be covered if their luck runs out. In other words, the ACA pool has a non-representative ratio of sick:healthy individuals. (See above re. "insolvency")
One-size-fits-all plans means paying for coverage you could not possibly need, while being poorly covered for what you do. Great-grandma has no need for maternity care!
In short, ACA took everything that was wrong with the US health care system, and made it official policy.
Don't get sick!
