The complaint charges that OFTACOOP – also known as Cooperativa de MA dico OftalmA3logos de Puerto Rico – unlawfully orchestrated an agreement among competing ophthalmologists to refuse to deal with a health plan, MCS Advantage, Inc., and its network administrator, Eye Management of Puerto Rico, LLC. OFTACOOP’s concerted refusal to deal forced MCS to abandon its plan to engage Eye Management to create a lower-cost network of ophthalmologists. MCS was also forced to maintain its then-current reimbursement rates paid to ophthalmologists.
