In Tennessee, the state insurance commissioner approved a 36 percent rate increase for the largest health insurer in the state’s individual marketplace. In Iowa, the commissioner approved rate increases averaging 29 percent for the state’s dominant insurer. Health insurance consumers logging into HealthCare.gov on Sunday for the first day of the Affordable Care Act’s third open enrollment season may be in for sticker shock, unless they are willing to shop around. Federal officials acknowledged on Friday that many people would need to pick new plans to avoid substantial increases in premiums.

Obamacare’s third open enrollment season kicked off yesterday, beginning the next chapter in its turbulent history. Today’s post discusses what we know about Obamacare. Tomorrow’s will discuss what we don’t yet know.

Obamacare premium costs will soar 20.3 percent on average in 2016 instead of the 7.5 percent increase claimed by federal officials, according to an analysis by The Daily Caller News Foundation. The discrepancy is because the government excluded price data for three of the four Obamacare health insurance plans when the officials issued their recent forecast claiming enrollees would face only a 7.5 percent average rate increase in 2016.

As eligible Americans today begin to examine health insurance plans on the government’s exchange under the Affordable Care Act’s annual open enrollment period, they will find 2016 premiums that have jumped on average by double-digit percentages compared to this year and 2014.

Obamacare’s third year of open enrollment began on Sunday. People hoping to sign up saw a website with fresh photos and high-tech features. They found the actual insurance of the president’s signature law has gotten even worse. Unless something dramatic happens, this may be the year of the health care law’s collapse. Prices keep rising and service keeps fading. It should not surprise the administration that people are not signing up.

New analysis from Avalere Health examines the 2016 Federal Exchange Premium File. According to HHS, more than 8 in 10 (86 percent) of current enrollees can find a lower premium plan in the same metal level by returning to the exchange and shopping for 2016. As a result, tables and figures below examine the lowest cost options in two metal levels.

The next Open Enrollment period for the Health Insurance Marketplace begins on November 1, 2015 for coverage starting on January 1, 2016. According to an HHS analysis, about 8 out of 10 returning consumers will be able to buy a plan with premiums less than $100 dollars a month after tax credits; and about 7 out of 10 will have a plan available for less than $75 a month. Highlights of the 2016 Marketplace Affordability Snapshot include:

About 70% of those who return to the federal insurance exchange when open enrollment starts Nov. 1 will pay less than $75 a month after they receive tax credits, a government analysis released Monday shows. The Centers for Medicare and Medicaid Services also reported that for this third open enrollment about 80% of consumers shopping again on Healthcare.gov will be able to pay less than $100 a month after tax credits.

For years, this blog has been warning about how the high cost of Obamacare-sponsored insurance would limit the law’s expansion of health coverage. Well, the chicken has come home to roost. Today, the Obama administration announced that it projected dramatically lower enrollment growth for Obamacare’s exchanges in 2016: only 1.3 million, compared to a prediction of 8 million when the law was passed five years ago.

Fewer than 1 million new customers nationwide will have health insurance from the Obamacare exchanges next year, according to a federal report published Thursday.

The Department of Health and Human Services estimates that 10 million people will be covered by private health insurance policies obtained via the Affordable Care Act’s exchange marketplaces in 2016, an increase of just 900,000 from the 9.1 million people the department estimates will have such plans by the end of this year.
