South Carolina: Preliminary 2019 #ACA rate hikes: 9.2% instead of ~2.3% *lower* without #ACASabotage

The only confusing thing about South Carolina's 2019 rate filings is that I'm not sure whether the "BlueChoice Health Plan" should be rolled in with the main Blue Cross Blue Shield of SC population. Carriers often have multiple listings in the same state for different policy lines, but they're generally listed under the same official corporate name. In this case, "BlueChoice" (which is clearly still part of BCBS) has a completely seaparate listing.

The BCBS filing clearly states the number of enrollees as around 203,000 people. The BlueChoice listing doesn't give a membership number, but appears to be roughly 6,800 people based on the full premium dollars they received in all of 2017 ($53.5 million divided by 12 months, divided by the statewide average of $654/month this year). This doesn't really make much difference, however, since BCBS still holds nearly 99% of the market anyway.

Assuming an 11.5% #ACASabotage factor (mandate repeal + shortassplans), this translates into unsubsidized enrollees having to pay an extra $900 than they'd otherwise have to (a 9.2% rate increase instead of a 2.3% rate drop).
