Counties around the US where Obamacare no longer has any insurance companies

Not only is the problem seen in Tennessee, but it looks like Iowans could lose it for almost their entire state. From USA Today:

Medica, a Minnesota-based health insurer, released a statement suggesting it was close to following two larger carriers in deciding not to sell such policies in Iowa for 2018, because of instability in the market.
“Without swift action by the state or Congress to provide stability to Iowa’s individual insurance market, Medica will not be able to serve the citizens of Iowa in the manner and breadth that we do today. We are examining the potential of limited offerings, but our ability to stay in the Iowa insurance market in any capacity is in question at this point,” the company’s statement said.
Medica’s move comes on the heels of announcements last month that Aetna and Wellmark Blue Cross & Blue Shield are pulling out of Iowa’s individual health insurance market. Those are the only three choices for individual health insurance in most areas of the state this year. . . .
If Medica leaves, that will mean that 94 of the 99 counties in Iowa will have no insurer for their Obamacare exchange.
