SAS Name

This variable identifies the beneficiary copay amount for a 2 month supply of the drugs on this tier, using an in-network preferred pharmacy (INPP; also known as a preferred pharmacy within a split network) during the pre-initial coverage limit (ICL) phase of the Part D benefit.


Plans that use a coinsurance percentage amount rather than a co-payment will not have a value in this field; see instead the corresponding coinsurance variable called (PRE_ICL_INPP_COINS_2M).

Starting in 2016, CMS changed how they describe pharmacy networks. The INPP are currently referred to as preferred pharmacies within split networks. There is no change in the meaning of the variable, and the data values are the same over time.

The CCW constructs the Plan Characteristics File from information submitted by plan sponsors to CMS’s Health Plan Management System (HPMS).
