West Virginia residents will see a double-digit premium increase for Obamacare plans in 2018, and is just the latest state to experience major rate hikes.

The state's insurance regulator reported late Tuesday that premiums for Highmark West Virginia will rise by about 25 percent, and the only other insurer, CareSource, will see hikes of 19.6 percent, according to a report in MetroNews.

The increase is below the average increase from 2016 of 32 percent in monthly premiums, MetroNews said.

West Virginia is the latest state to grapple with high Obamacare rates. Insurers have raised prices in several other states due to a variety of factors such as the federal government's inability to pay insurer subsidies, and a sicker-than-expected insurance risk pool.
