  5. During 2016, the average premium continued to drop, most likely due to plan elections by newly eligible beneficiaries, who are likely to enroll in plans with below-average premiums. The average PDP premium fell from $39.21 in February to $38.97 in April to $38.57 in September, a net drop of 1.6 percent in seven months.

  6. The weighted average premium is projected to increase by 9 percent from $29.08 in 2016 to $31.81 in 2017 for basic-benefit PDPs and by 10 percent from $52.01 to $57.13 for enhanced-benefit PDPs.

  8. Beginning in the 2017 plan year, CMS has suggested that Part D plans change the designation of the tier formerly labeled as non-preferred brand drugs to non-preferred drugs. This reflects the fact that some drugs in this tier are generics. Some plans label their tier for non-preferred generic drugs as simply generic drugs.

  9. We use weighted median amounts to characterize typical cost sharing.

  10. Because there are small differences in cost sharing for the same PDP across regions, PDPs in the Delaware/Maryland/DC region are used for these examples.

  11. Plans qualifying through the de minimis policy are eligible for new enrollees, but will not receive auto-assigned enrollees.

  12. These counts of benchmark plans include those designated as de minimis plans, which will not receive auto-assigned enrollees.

  13. Estimates for the total number of beneficiaries who are subject to paying a premium are based on plan data from the landscape and crosswalk files, together with CMS enrollment reports. Data from these files do not allow us to estimate how many will be reassigned.
