Here’s how the fraud worked, the insurer said in its counterclaim:Brokers would scout out people in 12-step programs, Alcoholics Anonymous meetings, homeless shelters and jails, then refer these clients to the “highest-bidding clinic.”Clinics that were not part of the insurer’s network paid clients’ insurance premiums and out-of-pocket costs such as deductibles and co-payments.The result was that people secured Health Net coverage “arranged and bought for them by financially-interested providers for one purpose only: to obtain coverage for the limited time needed to rack up millions of dollars in substance abuse treatment.” Some clinics misrepresented the home addresses of patients, many of whom lived out of state.
