Low-income subsidy (LIS) assistance for Part D, also called “Extra Help,” is a program to help people with lower incomes pay for Part D drug costs like premiums, deductibles, and coinsurance.[1][2]

Depending on your income and assets you may qualify for full or partial help.

In terms of benefits, the Extra Help program:

  • Reduces your premium up to a state-specific benchmark amount based on income (this means at full assistance, Part D plans with premiums below the benchmark amount can have $0 premiums).
  • Can help lower your out-of-pocket spending on drugs by ensuring you pay either the Extra Help copayment amount or your plan’s copay (whichever is cheaper).
  • Generally pays the full cost of drugs during your plan’s catastrophic coverage phase.
  • Gives you one Special Enrollment Period a year you can use to switch Part D plans.
  • Eliminates the Part D late enrollment penalty.
