BCBSNC

There are only two insurance carriers participating in the North Carolina individual market this year: Blue Cross Blue Shield and Cigna. That's expected to change for 2019, as Centene (aka Ambetter) is expected to jump into the NC market, but in terms of premium changes, it's just BCBS and Cigna which can be counted in my 2019 Rate Hike project.

Cigna hasn't released their 2019 filings publicly yet, but they only held around a 4% market share last year (around 21,000 enrollees) so unless they raise or lower rates by a huge amount, it's unlikely to move the needle much one way or the other.

The other 96% of the NC individual market belongs to Blue Cross...and they just issued a very public statement about their intentions for 2019:
