As I noted last week, insurance carriers in North Carolina were supposed to have submitted their preliminary 2019 premium rate change filings as of May 21st. Unfortunately, as I also noted last week, those "deadlines" appear to be more "guidelines" in many states, with North Carolina among them; there's no publicly-available premium change data available yet.
Insurers that wish to offer individual market coverage in North Carolina in 2019 had to file rates and forms by May 21, 2018. The two insurers that offer 2018 coverage in the North Carolina exchange — Cigna and Blue Cross Blue Shield of North Carolina — have both filed rate for 2019. Although the filings do show up in SERFF, they have very little publically available data at this point.
