(2) Calculation of the low-income benchmark premium amount. (i) The low-income benchmark premium amount for a PDP region is a weighted average of the premium amounts described in this paragraph (b)(2)(ii) of this section , with the weight for each PDP and MA-PD plan equal to a percentage, the numerator being equal to the number of Part D eligible individuals enrolled in the plan in the reference month (as defined in §422.258(c)(1) of this chapter) and the denominator equal to the total number of Part D eligible individuals enrolled in all PDP and MA-PD plans (but not including PACE, private fee-for-service plans or 1876 cost plans)in a PDP region in the reference month. (ii) Premium amounts: The premium amounts used to calculate the low-income benchmark premium amount are as follows: (A) The monthly beneficiary premium for a PDP that is basic prescription drug coverage; (B) The portion of the monthly beneficiary premium attributable to basic prescription drug coverage for a PDP that is enhanced alternative coverage; or, (C)The MA monthly prescription drug beneficiary premium (as defined under section 1854(b)(2)(B) of the Act) for a MA-PD plan. (c) Special rule for 2006 to weight the low-income benchmark premium. For purposes of calculating the low-income benchmark premium amount for 2006, CMS assigns equal weighting to PDP sponsors (including fallback entities) and assigns MA-PD plans a weight based on prior enrollment. New MA-PD plans are assigned a zero weight. PACE, private fee-for-service plans and 1876 cost plans are not included. (d) Other low-income subsidy eligible individuals—sliding scale premium. Other low-income subsidy eligible individuals are entitled to a premium subsidy based on a linear sliding scale ranging from 100 percent of the premium subsidy amount described in paragraph (b) of this section as follows: (1) For individuals with income at or below 135 percent of the FPL applicable to their family size, the full premium subsidy amount. (2) For individuals with income greater than 135 percent but at or below 140 percent of the FPL applicable to the family size, a premium subsidy equal to 75 percent of the premium subsidy amount. (3) For individual with income greater than 140 percent but at or below 145 percent of the FPL applicable to the family size a premium subsidy equal to 50 percent of the premium subsidy amount. (4) For individuals with income greater than 145 percent but below 150 percent of FPL applicable to the family size a premium subsidy equal to 25 percent of the premium subsidy amount.
