The geniuses behind Obamacare certainly get surprised a lot.  Either they are not the experts they claimed to be, or maybe, just maybe they were lowballing us all along about the costs of the plan.  And, to the surprise of nobody but an Obama administration health care expert (as CNN Money reports):

Patients in Obamacare are sicker and need significantly more medical care than those in employer-sponsored plans, according to a new Blue Cross Blue Shield Association report.

This raises fresh concerns about the possibility of steep rate hikes for 2017 and of insurers leaving the Obamacare exchanges.

The study, the first of its kind to look at millions of enrollees across the country, found that Obamacare members have higher rates of costly illnesses such as diabetes, depression, hypertension, heart disease, HIV and Hepatitis C.

They also use more medical services -- including emergency rooms, in-patient hospital care, doctors and prescriptions than patients in employer-sponsored plans. Their cost of care was 22% higher than those in work-based health plans in 2015, or $559 a month, on average, for Obamacare enrollees versus $457 for those in employer plans.
