The health insurance world has been in constant flux since the implementation of the ACA in 2010. The end of the first open enrollment period for the Health Insurance Marketplace yielded a lot of numbers. Everyone knows that over 8 million people bought plans on the exchanges. But not everyone has heard the numbers in the following 15 surprising statistics about contemporary American health insurance!

1. 129 million American adults and 17.6 million American children have preexisting conditions, like asthma or diabetes. This means that half of the population has some type of preexisting condition. Luckily, the ACA contains provisions that prevent insurance companies from discriminating against those with preexisting conditions.

2. One quarter of people who qualified for premium subsidies during the inaugural open enrollment period did not have bank accounts. I’m not really sure how I ever lived without my bank’s iPhone app, so this one really surprised me!

3. Health care spending directly related to the ACA (now that more people have and use insurance), saved the U.S. economy from recording a negative growth rate in the first business quarter of 2014. Health care spending increased at a 9.9% annual rate, contributing 1.1 percentage points to GDP growth.

4. The ACA levied a 10% federal excise on tanning services. This is sometimes it’s called the “Snooki” tax, after the tanned reality TV star.

12. Of the 8 million people who selected Marketplace plans during open enrollment, 65% of them chose a silver metal level plan, and 85% of them purchased a plan with financial assistance.

13. Despite an eligibility rate of 88%, only 66% of employees eligible to purchase employer-provided benefits actually did so in 2013. This is due largely to the fact that young workers are less likely to accept benefits because they can stay on their parents’ plans until age 26.

14. A South Florida ophthalmologist received $21 million in 2012 from the tax-payer funded Medicare program — more than any other doctor in the country. Needless to say, the FBI is checking him out.
