This variable is the dollar amount of the Part D Premium Enhanced (supplemental) Rate. This amount is net of any Part A/B rebates applied to "buy down" the drug premium for Medicare Advantage plans.


The Part D Supplemental Premium covers any enhanced benefits that may be offered by
a plan above and beyond the basic (standard) Part D benefit. These benefits may
include extra coverage in the coverage gap, lower copayments than the standard
benefit, coverage of non-Part D drugs (e.g. benzodiazepines prior to 2013), etc.

The CCW constructs the Plan Characteristics File from information submitted by plan
sponsors to CMS’s Health Plan Management System (HPMS). Employer and National
Program of All-inclusive Care for the Elderly (PACE) plans are waived from reporting Plan
Benefit Package information.

For those plans that did not report, the value of this variable will be blank.
