Anthem will not sell insurance plans in Obamacare’s exchange in Nevada next year, as it becomes the latest insurer to defect from the law’s marketplace.

Anthem’s decision, announced by Nevada’s insurance regulator Monday, comes as insurers are starting to set their rates and participation in Obamacare’s exchanges for next year. Congress is aiming to create a bipartisan deal to boost the individual market, which includes the law’s exchanges, by the end of September.
