Aetna (AET)  announced late yesterday that it will completely withdraw from the ObamaCare marketplace in 2018, a decision Health and Human Services Secretary Tom Price perceived as a sign of continued instability in the health care sector under the Affordable Care Act, acceding to Fox Business News.

"Aetna's decision to completely withdraw from the ObamaCare exchanges adds to the mountain of evidence that ObamaCare has failed the American people. Repealing and replacing it with patient-centered solutions that stabilize the marketplace to bring down costs and increase choices is the only solution," Price said late Wednesday.

The company will not offer insurance plans in Delaware or Nebraska, the remaining two states where it was slated to provide coverage under the Affordable Care Act next year.

"At this time [we] have completely exited the exchanges," Aetna said in a statement to Fox Business.
