GAP_TIER_DRUG_TYPE

This variable identifies what types of drugs, if any, are covered on each formulary tier during the coverage gap phase. A tier may include multiple drug types.

Comments

This field is only populated if the plan has an enhanced benefit design with extra coverage in the gap. There is variation in the number of formulary tiers over time. The coverage gap is technically referred to as the initial coverage limit (ICL) for the Part D benefit.

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.
