What legal action is CDA taking?

Delta Dental of California’s 2023 changes to reimbursement rate structure and provider agreements have a significant impact on many members’ practices. CDA is pursuing litigation intended to require Delta Dental to honor its contractual obligations inherent in the Participating Dentist Agreement between Delta and its participating providers. CDA is also challenging whether the Delta Dental board of directors has violated its legal responsibilities, referred to as fiduciary duties.

Past legal and legislative victories


In 2018, CDA achieved a favorable settlement on behalf of dentists – and their right to fair dealings – in our litigation against Delta Dental. During five years of hard-fought litigation, we successfully blocked Delta’s attempt to reduce reimbursement rates for the Premier Plan, saving providers more than $600 million. CDA has also driven multiple legislative wins on behalf of plan transparency, accountability and provider reimbursements.
