WASHINGTON -- Having health insurance used to hinge on where you worked and what your medical history said. Soon that won't matter, with open-access markets for subsidized coverage coming Oct. 1 under President Barack Obama's overhaul.
But there's a new wild card, something that didn't seem so critical when Congress passed the Affordable Care Act back in 2010: where you live.
Entrenched political divisions over "Obamacare," have driven most Republican-led states to turn their backs on the biggest expansion of the social safety net in a half century. If you're uninsured in a state that's opposed, you may not get much help picking the right private health plan for your budget and your family's needs.
The differences will be more glaring if you're poor and your state rejected the law's Medicaid expansion. Unless leaders reverse course, odds are you'll remain uninsured. That's because people below the poverty line do not qualify for subsidies to buy coverage in the markets.
"We are going to have a new environment where consumers may be victims of geography," said Sam Karp of the California HealthCare Foundation, a nonprofit helping states tackle practical problems of implementation. "If I'm a low-wage earner in California, I may qualify for Medicaid. With the exact same income in Texas, I may not qualify."
The health care law is finally leaving the drawing boards to become a real program with citizens participating. But in many parts of the country, the decisions of Republicans opposed to the law will trump the plans of Democrats who wrote it.
Still, there is a new bottom line. Health insurance marketplaces in every state will provide options for millions of people who don't have job-based coverage, who can't afford their own plan or have a health problem that would get them turned down. The feds will run the markets in states that refused to do so.
The coverage won't be free, even after sliding-scale subsidies keyed to your income.
That's significant because starting next year most Americans will also have a legal obligation to get covered or face fines. Some people who now purchase bare-bones individual plans will complain the new ones cost too much. Others, in good health, may resent the government telling them to purchase insurance they don't think they need.
Nonetheless, the number of uninsured people is expected to drop markedly, bringing the United States closer to other economically advanced countries that guarantee coverage.
The combination of subsidized private insurance through the new markets, plus expanded Medicaid in states accepting it, could reduce the number of uninsured by one-fourth or more next year. Current estimates of the uninsured range from around 49 million to well over 50 million.
As Americans get more familiar with the law -- and if more states accept the Medicaid expansion -- millions more should gain coverage. Many of the remaining uninsured will be people living in the country illegally. They are not entitled to benefits.
In Texas, Republican Gov. Rick Perry has vowed not to facilitate "Obamacare." But Cecilia Fontenot of Houston is looking forward to the opening of that state's federally run insurance market.
A part-time accountant in her early 60s, Fontenot is uninsured and trying to stay healthy while coping with diabetes, high blood pressure and high cholesterol. She walks twice a day, early in the morning before it gets hot, and in the evenings.
Also on her mind is a breast lump detected about a year ago. Her doctor recommended a digital mammogram, but she has not been able to afford the more involved test.
"I try not to worry and just pray on it," said Fontenot.
Because of her pre-existing conditions, Fontenot would have a tough time finding affordable individual coverage today. But starting Jan. 1, insurers will no longer be able to turn away people with health problems or charge them more.
And the government will provide sliding-scale tax credits that can make premiums more affordable for households earning between 100 percent and 400 percent of the federal poverty line. That's $11,490 to $45,960 for an individual, $23,550 to $94,200 for a family of four.
People on the low end of the income scale get more help, as will older people, whose premiums are higher.
With an annual income of about $23,000, Fontenot makes too much to qualify for Medicaid. And her state decided not to expand the program, an option the Supreme Court granted last year as it upheld the rest of Obama's law.
But she would qualify for subsidized private coverage in the federally run Texas marketplace. She could apply online, through a call center, by mail or in person.
After the government verifies her identity, legal residence and income, Fontenot would be able to take her tax credit and use it to pick an insurance plan. Coverage takes effect Jan. 1.
She'd have up to four levels of coverage to choose from: bronze, silver, gold and platinum. All cover the same benefits, but platinum has the highest premiums and lowest out-of-pocket costs, while bronze has the lowest premiums and highest out-of-pocket costs.
Fontenot's share of premiums would be capped at 6.3 percent of her income, or $1,450 a year for a benchmark silver plan. She'd have to squeeze about $120 a month out of her budget, and that doesn't include her annual deductible and copayments.
"If I want to stay alive, I'm going to have to budget that in," said Fontenot.
With insurance, she'd switch to a brand-name diabetes drug that does a better job of controlling her blood sugars -- and get that mammogram.
"I am not asking for free stuff," she added. "I am willing to do my part."
Like Fontenot, many of the people who'll access the markets Oct 1 will have health problems. It's where the greatest need is.
But two other groups are critical to the program's success: Healthy uninsured people, many of them in their 20s and 30s, and insured people who will switch over from existing individual policies.
Healthy individuals are needed to help pay for the sick.
And with instant feedback via social media, reviews by people switching from existing individual plans could define early consumer sentiment.
Some of those transitioning will be looking for better deals. Others will be there because their insurers canceled policies that didn't meet the law's minimum standards, and they may be upset.
Consumers don't have to decide on Oct. 1. You have until Dec. 15 to sign up if you want coverage by Jan. 1. And you have until next Mar. 31 if you want to avoid penalties for 2014. Fines start as low as $95 the first year but escalate thereafter.
Procrastinate beyond Mar. 31, and you'll have to wait until the next open enrollment period in Oct. 2014, unless you have a life-changing event like job loss, divorce or the birth of a child.
Former Medicare chief Mark McClellan, who oversaw the rollout of seniors' prescription drug benefits for Republican President George W. Bush, says his advice is not to sign up right away, but not to wait too long either. In other words, check things out. Buying health insurance is not as simple as shopping on Amazon.
"This is a milestone along the path but by no means the end of the road," said McClellan. "There's a lot more of a journey to see if it can really succeed."
Three key things to watch for are premiums, choice and the consumer shopping experience.
Premiums so far are averaging lower than what government experts estimated when Congress was debating the law. That's important for policy types, but it may not mean much to consumers. Current low-cost individual market policies are difficult to compare with the new plans, which offer better financial protection and broader benefits.
Plan choices seem adequate, but networks of hospitals and doctors may be tightly restricted to keep premiums low.
The biggest unknown is how consumers will feel about the whole experience. Many will be unfamiliar with health insurance basics, and applying for subsidies may feel like plodding through tax forms.
Still, after years of polemic debate and a Supreme Court decision -- and even as congressional Republicans keep trying to repeal it -- "Obamacare" will finally be in the hands of American consumers.
