651 CMR 15.09
Coordination of Benefits
A Member shall have access to Covered Benefits under the Plan only after said Member has
exhausted all other prescription drug coverage, including all coverage available under the
Member's Medicare Part D Plan or Creditable Coverage Plan.
(1) For Members with coverage under a Medicare Part D Plan or Creditable Coverage Plan, the
Plan shall coordinate benefits by providing Supplemental Assistance as established for the
applicable Membership Category.
(2) For Members who are not eligible for Medicare Part D coverage, but have another form of
Prescription Drug Coverage, if a Prescription Drug is not a Covered Benefit under the other
Prescription Drug coverage, but is a Covered Benefit under the Plan, the Plan will be the primary
payor for that Prescription Drug.
