This variable identifies the beneficiary co-insurance percentage for a 1 month supply of the drugs on this tier, using an in-network pharmacy during the pre-initial coverage limit (ICL) phase of the Part D benefit.


This variable was new in 2007. Plans that use a co-payment amount rather than a coinsurance percentage will not have a value in this field; see instead the corresponding co-payment variable called (PRE_ICL_INP_COPAY_1M). This variable also appears in the Plan Characteristics - Base File (see PRE_ICL_INP_1M_COINS_TIER_01 - PRE_ICL_INP_1M_COINS_TIER_09). The CCW constructs the Plan Characteristics File from information submitted by Part D plan sponsors to CMS’sHealth 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.
