MDL 2931Antitrust

Delta Dental Antitrust Litigation

The causation theory is based on the allegation that Delta Dental used its monopsony power to manipulate reimbursement rates and territorial divisions, thereby suppressing competition and harming dental providers financially. This abuse of market power led to reduced reimbursements, limited provider participation, and restricted market access, which collectively caused economic harm to providers and reduced competition in the dental insurance market [CourtListener](https://www.courtlistener.com/docket/258174/in-re-delta-dental-antitrust-litigation), [Keller Rohrback](https://www.kellerrohrback.com/currentcases/delta-dental-antitrust-litigation).
