The Delta Dental Plans Association has weighed in on what DeCare Dental L.L.C. can and cannot do for Delta Dental of Minnesota.

The Delta Dental Plans Association, Oak Brook, Ill., is a group that represents 39 Delta Dental dental carriers.

WellPoint Inc., Indianapolis, recently acquired DeCare Dental, Eagan, Minn., a dental plan administration that has been running dental plans for several Delta Dental carriers, including WellPoint’s Empire Blue Cross unit.

DeCare still can provide some administrative services for Delta Dental of Minnesota, Eagan, but Delta Dental of Minnesota must handle other functions, according to the Delta Dental association.

“To ensure confidentiality and security for Delta Dental subscribers, modifications will be made to applicable information technology systems to isolate Delta Dental subscriber information from other entities that DeCare serves, including WellPoint,” the Delta Dental association says.

Neither WellPoint nor any other benefits provider outside the Delta Dental system will have access to Delta Dental networks or the Delta Dental brand, but Delta Dental carriers can continue to use DeCare for some types of administrative services, “with strong safeguards for confidentiality,” according to Kim Volk, president of the Delta Dental association.
