Conn. Gen. Stat. § 17b-226a: Provider billing rates for goods and services.

A pharmacy provider enrolled in any medical assistance program administered by the Department of Social Services, when billing the department for a good or service, shall bill the department the lowest amount accepted from any member of the general public who participates in the pharmacy provider's savings or discount program. For purposes of this section, “savings or discount program” means any program, club or buying group offered by a pharmacy provider to any member of the general public for the purpose of obtaining a lower charge for any good or service than the charge made to any member of the general public who does not participate in such program.
