Comments
This variable was new in 2007. It changed from 12 digits to 8 in 2009.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_1M_COPAY_TIER_01).There a different number of variables each year to describe tiers, due to variation in the formulary tiers over time. There are different variables to describe all possible tiers in the pre-ICL benefit phase. See also PRE_ICL_INP_1M_COINS_TIER_01 - PRE_ICL_INP_1M_COINS_TIERS_09.
