More than half of the states have disclosed just how much higher their health care premiums could be next year under the Affordable Care Act, and some of the potential increases are jaw-dropping.

But Illinois residents won’t get their first look at proposed 2017 premiums until Aug. 1, and that has consumer advocates frustrated.

Insurance companies had to submit rate plans for Illinois in April, but the state doesn’t require the proposals to be made public upon filing, according to the Department of Insurance. In addition, the director of the department considers health plan filings confidential and exempt from Freedom of Information requests.

UnitedHealthcare will stop offering Affordable Care Act plans in Illinois in 2017, the Tribune confirmed Tuesday.

The departure of the insurance company will reduce the number of coverage options for consumers in 27 counties.

UnitedHealthcare announced in April that it would pull out of nearly all of the ACA exchanges because of heavier-than-expected losses from covering a population that turned out to be sicker than it expected. The ACA plans, which the company offered in 34 states this year, are a small share of UnitedHealthcare’s total business.

Enrollment in individual health care plans, now dominated by the Affordable Care Act exchanges, fell 15.4 percent in the first quarter for the parent of Blue Cross and Blue Shield of Illinois.

At the end of March, Chicago-based Health Care Service Corp. had 1.39 million individual members, compared with 1.64 million as of Dec. 31.

The decline in individual members is even greater when compared with the first quarter of 2015. A year ago, HCSC had nearly 1.9 million individual market members.

Despite the decline in individual enrollment, the insurer set aside $431.5 million in reserves during in the first quarter to account for losses expected in its 2016 ACA business, according to first-quarter financial statements filed this week with the Illinois Department of Insurance.

In the face of losses in the Affordable Care Act marketplace, Blue Cross and Blue Shield of Illinois is looking for new ways to cut spending.

Starting June 1, the Chicago-based health insurer will no longer accept credit cards as a form of payment for members who buy their own health insurance on or off the Illinois marketplace. The company began notifying customers of the change last month. Blue Cross will still accept other forms of payment, including debit cards.

If you bought health insurance last year through Obamacare, you may be pleasantly surprised at tax time to find out you have money coming to you.

But it’s just as likely the surprise will go the other way: You might owe Uncle Sam some money if the government subsidy you received for buying insurance through the Affordable Care Act marketplace was too large based on your income. And if you skipped buying health insurance entirely, you probably will face a penalty. On average, those penalties this year are running $383 among H&R Block customers. That’s an increase from $172 a year ago.

If this is confusing or unpleasant, don’t decide to ignore the matter.
