Notes
1. Premiums include both amounts withheld from Social Security benefit checks (and other certain Federal benefit payments) and amounts paid directly to Part D plans.  The premiums paid directly to Part D plans are not displayed on Treasury statements and are estimated. 
"2. Includes, net of transfers from States, all government transfers required to fund benefit payments, administrative expenses, and State expenses for making low-income eligibility determinations."
"3. With the availability of Part D drug coverage and low-income subsidies beginning in 2006, Medicaid is no longer the primary payer for full-benefit dual eligibles.  States are subject to a contribution requirement and must pay the Part D account in the SMI trust fund a portion of their estimated forgone drug costs for this population.  Starting in 2006, States must pay 90 percent of the estimated costs, with this percentage phasing down over a 10-year period, to 75 percent in 2015 and later."
"4. Includes payments to plans, subsidies to employer-sponsored retiree prescription drug plans, payments to States for making low-income eligibility determinations, Part D drug premiums collected from beneficiaries and transferred to Medicare Advantage plans and private drug plans, and premium amounts paid directly by enrollees to plans.  (The last item is on an estimated basis; see note 1.)  Includes amounts for the transitional assistance benefits in 2004-2007."
"5. Section 708 of Title VII of the Social Security Act modifies the provisions for the delivery of Social Security benefit checks when the regularly designated delivery day falls on a Saturday, Sunday, or legal public holiday.  Delivery of benefit checks normally due January 3, 2010 occurred on December 31, 2009, delivery of benefit checks normally due January 3, 2016 occurred on December 31, 2015, and delivery of benefit checks normally due January 3, 2021 occurred on December 31, 2020. Consequently, the Part D premiums withheld from these benefits were added to the Part D account on December 31, 2009 (about $209 million), December 31, 2015 (about $184 million), and December 31, 2020 (about $137 million).  These premiums are excluded from the premium income for calendar year 2010, 2016, and 2021. "
"6. Section 708 of Title VII of the Social Security Act modifies the provisions for the delivery of Social Security benefit checks when the regularly designated delivery day falls on a Saturday, Sunday, or legal public holiday. The expected payment date for those benefits normally due January 3, 2027 is December 31, 2026. Accordingly, an estimated $0.2 billion will be added to the Part D account on December 31, 2026."
