These individuals will pay the income-related monthly adjustment amount in addition to their Part D premium. Part D premiums vary by plan and, regardless of how a beneficiary pays their Part D premium, the Part D income-related monthly adjustment amounts are deducted from Social Security benefit checks or paid directly to Medicare. The 2025 Part D income-related monthly adjustment amounts for high-income beneficiaries are shown in the following table:
