 WDS ceded the administration for enrollees in other states to other Delta Dental member companies and contracted with the Blue Cross and Blue Shield Association for administration in those states without a Delta Dental affiliate organization.Coverage was provided this way until the late 1980s when Delta Dental of California won the bid for the Office of the Civilian Health and Medical Program of the Uniformed Services (OCHAMPUS) program.Delta Dental member companies agreed to share its provider data so the administration of this very large account could be centralized, with Delta Dental of California sharing the administrative income and risk.
