Arizonans without health insurance fell from 20.4 percent of state residents in 2013 to 17.5 percent in 2014, further proof that Obamacare is working, the White House said Tuesday.

Gov. Doug Ducey may have just cost more than 200,000 Arizonans a shot at keeping the health insurance they received through the Affordable Care Act, though they won’t know for sure until the U.S. Supreme Court rules this summer.

Americans who did not have health insurance last year might have to pay a penalty when they file their federal income taxes this year – but some people who did have coverage might owe Uncle Sam, too.

On an 18-11 margin the Senate on Wednesday gave final approval to legislation barring Arizonans who purchase health insurance through the Affordable Care Act from getting coverage for elective abortions, even if they pay a separate premium out of their own pocket.

The state House voted Monday to deny coverage for women for elective abortions if they get their insurance through the Affordable Care Act.

The Obama administration’s willingness to cut deals with Republican states as a way of getting them to cover more people under the Affordable Care Act has given Arizona’s conservative leaders the perfect opening to push for premiums and bigger copays on Medicaid members.

The last time the U.S. Supreme Court gave states an option of whether to comply with a key provision of the Affordable Care Act, Arizona embraced Medicaid expansion, despite then-Gov. Jan Brewer’s stated opposition to the federal health care law.

The number of Arizonans signing up for health insurance on the federal marketplace has surpassed last year's total by nearly 55,000 people.

The cost of being uninsured in America is going up significantly next year for millions of people. It's the first year all taxpayers have to report to the Internal Revenue Service whether they had health insurance for the previous year, as required under President Barack Obama's law. Those who were uninsured face fines, unless they qualify for one of about 30 exemptions, most of which involve financial hardships.

Open enrollment for the second phase of President Barack Obama's health care law opened over the weekend with less fanfare than the original rollout that was plagued by computer glitches. But this enrollment period will bring about many changes for Arizona residents, including the prospect of lower prices but shifting insurance providers.
