For all that has been written, spoken, screamed, and whispered about the Affordable Care Act, there is still a lot of confusion and lack of knowledge among the public. No wonder, I suppose. Republicans continue to attack it as if it were a scourge from hell. Democrats are desperate to tout it. Meanwhile, it keeps changing, as portions are altered, fixed, or dropped. Maybe it’s a good moment to take stock. For starters, after all those changes, what is Obamacare, exactly? What is out, what is on hold, and what is still standing in this large and controversial law? And what have been Obamacare’s plusses and minuses so far? Here’s the first of a two-part scorecard.

WHAT’S STILL STANDING?

The individual mandate.
This is the heart of the law—the requirement that everyone carry insurance or face penalties, and it is still scheduled to take effect January 1, with enrollment in the state health exchanges beginning October 1. Most Americans—about 160 million of them—are insured through their workplace, but some 50 million have no insurance at all. Many of those who have no coverage now will be able to shop in the state exchanges set up by the ACA and, depending on their income, receive a subsidy to help pay the premiums. Those with incomes up to 150 percent of the poverty level ($17,235 for individuals and $35,325 for a family of four) will get further help by having their out-of-pocket costs cut by as much as two-thirds. And if people have pre-existing conditions, they won’t be turned down for coverage.

An important wrinkle: Workers with employer coverage who pay more than 9.5 percent of their income for that insurance can shop in the exchange and receive subsidies for themselves or their families. But because of the way the Treasury Department has interpreted this provision, if the worker’s contribution to an individual policy is less than 9.5 percent of income but the contribution to a family policy is more than that, family members are out of luck when it comes to getting subsidies.

Medicaid expansion.
One of the pillars of reform, Medicaid expansion, is sort of in and sort of out, thanks to the Supreme Court and several reluctant GOP-led states. Obamacare was supposed to bring coverage to some 15 million people through the expansion by raising the eligibility limit to 138 percent of the federal poverty level—or to about $32,500 for a family of four and $15,000 for a single person. The Supreme Court ruled that states had the option of dropping out of his expansion, however. By early July 19 states said they would not expand their Medicaid programs, 23 plus the District of Columbia said yes they would, while five were undecided and three were considering another kind of expansion. As a result, people with incomes below the poverty line—the poorest of the poor—are stuck if they live in states that have chosen not to expand. These people have almost no coverage options. They have little money to buy insurance on their own, and because of the way the law was written, they are barred from shopping in the exchanges and receiving subsidies.

Hospital penalties and bonuses.
These carrots and sticks aimed at encouraging better care remain in effect—despite grumbles and complaints from hospital officials. Medicare now penalizes hospitals for readmitting too many patients, though there have been fits and starts implementing the program. Medicare made some mistakes in calculating penalties and had to reduce them a bit, but so far has penalized about 2,200 hospitals. Hospitals also get bonuses or penalties if they meet or don’t meet certain targets that measure quality of care. One example of good care: giving beta blockers to patients who’ve had heart surgery. Hospitals scoring the highest were not necessarily the ones with brand name reputations.

WHAT’S OUT?

The CLASS Act
Short for the Community Living Assistance Services and Support Act, the CLASS Act was supposed to be a down payment on a national program to pay for long-term care, a big shortcoming in the US health system. It was a voluntary effort in which people could join a government plan and pre-fund their long-term care needs. When they needed care, they would get a daily cash benefit to pay for services. The program was none too popular with many politicians. In the end the government found it unsustainable. Because it was voluntary (meaning there was no mandate to buy here), lots of people had to sign up to make it viable. If they didn’t, premiums would rise, and very few people could afford them. There was no way, the government decided, to make the program actuarially sound over 75 years.
