This memo was prepared by analysts in the Office of the Assistant Secretary for Planning and Evaluation (ASPE) in consultation with the Office of the Actuary (OACT) of the Centers for Medicare & Medicaid Services (CMS). The net savings for traditional Medicare beneficiaries from reduced Part B premiums, reduced Parts A and B coinsurance and copayments, and from increased Part D premiums were estimated by OACT in 2010 (note: they have not been updated for actual experience from 2010 through 2012).2 Actual savings from reduced Parts A and B coinsurance will vary across beneficiaries. Beneficiaries with multiple chronic conditions, those using a higher-than-average volume of services, as well as those who make greater use of preventive services, will enjoy a greater-than-average amount of savings. The estimated effects for beneficiaries not reaching the donut hole are shown in Table 2.

The Affordable Care Act requires drug manufacturers to provide a discount for covered brand name Part D drugs sold to beneficiaries in the donut hole (50 percent starting in 2011) and provides subsidies for covered brand name Part D drugs to those beneficiaries rising from 2.5 percent in 2013 to 25 percent in 2020. Finally, the Affordable Care Act provides subsidies for generic drugs purchased in the donut hole beginning at 7 percent in 2011 and rising to 75 percent in 2020. Together, these changes mean that a beneficiary will pay the standard 25 percent coinsurance in a standard plan in 2020 for generic and brand drugs, and the donut hole will be closed.
Since the Affordable Care Act was enacted, 5.4 million people with Medicare have saved over $4.1 billion on prescription drugs in the donut hole, and an estimated 37 million people with Medicare have received a preventive benefit free of charge.3
The Affordable Care Act also lowers the rate of growth of the out-of-pocket threshold for drug spending by beneficiaries in the donut hole from 2014 to 2019. We estimate savings to beneficiaries from this change using a combination of information from OACT and results from the analysis described above.4
The estimates are presented in Table 3 below. For beneficiaries with spending in the donut hole, total estimated Parts A, B, and D savings increase from $735 in 2012 to $2,599 in 2022.

- Estimates for 2010-19 are provided by OACT, John Shatto's memo on October 5, 2010; and estimates for 2020-22 are computed by ASPE in consultation with OACT.
- Estimates by ASPE based on Medicare Part D data in 2010 generated by Acumen for ASPE (Non-LIS Beneficiaries with at least 1 Month in D in 2010) and the discounts to beneficiaries in 2011 are benchmarked to CMS analysis of 2011 PDE data.
Part D estimates incorporate 3 effects: (1) savings due to filling the doughnut hole, (2) savings due to reducingthe growth rate of the catastrophic threshold during 2014-19, and (3) an offset from increased part D premium.
