POST_OOPT_TIER_DRUG_TYPE

This variable identifies what types of drugs, if any, are covered on each formulary tier during the post-out-of-pocket threshold phase (also known as the catastrophic coverage phase). A tier may include multiple drug types.

Comments

This field is only populated if the Medicare-defined Post Threshold Cost Shares do not apply. There is variation in the number of formulary tiers over time. The catastrophic coverage phase is also referred to as the post-out-of-pocket threshold phase for the Part D benefit.

The CCW constructs the Plan Characteristics File from information submitted by Part D 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.
