Medicare Part D is the prescription plan component of Medicare.  Any individual served by DDS who has Medicaid (MassHealth, Commonwealth) and Medicare is considered dually eligible and should be enrolled in one of the Low Income Subsidy (LIS) plans.  LIS plans have no monthly premium payment and have a prescription fill and refill co-payments between $1 and $3.  The LIS plans may change from year to year so be sure to check each year when the Part D Update is posted here by DDS.  Information about the Medicare Part D prescription plans is available at .


  • Dually eligible individuals (those with both Medicare and Medicaid) can change their plans as often as they want.
  • All duals should be in a LIS plan if they want to avoid monthly premiums and have a reduced/limited copay for prescriptions.
