Evidence from 1998-2021 – Healthcare Economist

In the past, seniors in Medicare had to pay for all their prescription drugs out-of-pocket. For elderly individuals with multiple medical conditions, this lack of coverage was highly burdensome.

To address this issue, in 2006, Medicare Part D began which provided some coverage for prescription drugs. To keep the cost of Part D down, however, it contained a coverage gap (colloquially known as the “donut hole”) in which after patients met some deductible and had some coverage, they would again be responsible for all prescription drug cost until they reached their catastrophic coverage levels.

To address the donut hole’s burden on senior’s, the Affordable Care Act gradually reduced Medicare Part D beneficiaries’ coinsurance rate in the donut hole from 100% in 2010 to 25% in 2020.

A key question is how did these policy changes impact drug coverage and financial hardship. A paper by Olson et al. (2022) answers this question using survey data from 1998, 2001, 2015 and 2021. Using this approach, they find that:

Five percent of older adults lacked prescription drug coverage in 2021, continuing a downward trend from 32% in 1998, 29% in 2001, and 9% in 2015. Contrastingly, 20% of older adults reported financial hardship from prescription drug purchases in 2021, bending an upward trend from 19% in 1998, 31% in 2001, and 36% in 2015. Financial hardship from purchasing prescription drugs was more likely to be reported by older adults lacking prescription drug insurance, taking multiple medications daily, and having a low annual household income across all survey years
