Centene has completed its  $6 billlion acquisition of Health Net, creating the largest Medicaid managed-care organization.  California regulators’ approval of the deal paved the way for the transaction to close.

The acquisition expands Centene’s government products to include Medicare Advantage and contracts with Department of Defense and the Veterans Administration,  as well as expanding its role in the health-insurance marketplaces. The integrated company will be insuring more than 10 million members.

The Department of Justice and some state insurance departments are still reviewing Aetna’s acquisition of Humana as well as  Anthem’s  purchase of Cigna.
