The vast majority (87% on average between 2006 and 2010) stayed in the same Part D plan, even though the plans can change premiums, deductibles, cost-sharing amounts, and their list of covered drugs each year. Higher rates of plan switching were observed in PDPs that increased premiums, increased deductibles, or dropped coverage of brand-name drugs in the coverage gap.
