Centene said Monday it has entered into an agreement to acquire health care analytics company Apixio in a move that will provide the health insurer with artificial intelligence options to add to its technology lineup.

Walmart on Tuesday revealed its plan to enter the health insurance business through the launch of Walmart Insurance Services, which will sell Medicare insurance plans during this year’s annual enrollment period starting next week.

Centene Corporation, the largest provider of Health Insurance Marketplace plans, said Friday that it intends to grow its presence on the exchanges in 2021 by increasing the availability of its marketplace product suite in more than a dozen states.

Medicare Advantage insureds whose plans are administered by Centene and its subsidiary Wellcare, BlueCross BlueShield of Michigan and Anthem reported having the lowest levels of customer satisfaction in an annual J.D. Power survey, with a lack of communication being the key factor.
