Obamacare’s supporters scored a victory as health insurer Centene Corp. decided to dramatically expand in Nevada, filling in rural counties that were at risk of having no options next year.

Centene said Tuesday that it will sell statewide via its SilverSummit unit, a move that will help more of Nevada’s residents gain Affordable Care Act coverage. Nationally, the decision will reduce the number of empty counties to two: one in Ohio and one in Wisconsin.

Many of Centene’s rivals have pulled back from the ACA, citing financial losses and uncertainty about how the Trump administration will run the health law’s markets. Centene, seeing an opportunity to profit as others retreat, has plans to expand in nine states for next year. The company already had about 1.1 million Obamacare customers as of June 30.
