Title VI, SEC. 6105. EXCESS PREMIUM CREDIT. (a) In General. If plan payment reductions are made for one or more regional alliance health plans offered by a regional alliance for plan payments in a year under section 6021, the alliance shall provide for a credit under this section, in the amount described in subsection (b), in the case of each family enrolled in a regional alliance health plan offered by the alliance for premiums in the year. (b) Amount of Credit. (1) In general. Subject to paragraph (2), the amount of the credit under this subsection, for a family enrolled in a class of family enrollment for a regional alliance for a year, is the amount that would be the weighted average premium for such alliance, class, and year, if the per capita excess premium amount (determined under subsection (c)) for the alliance for the year were substituted for the reduced weighted average accepted bid for the regional alliance for the year. (2) Adjustment to account for use of estimates. Subject to section 1361(b)(3), if the total payments made by a regional alliance to all regional alliance health plans in a year under section 1351(b) exceeds (or is less than) the total of such payments estimated by the alliance (based on the reduced weighted average accepted bid under subsection (c)(1)), because of a difference between (A) the alliance's estimate of the distribution of enrolled families between excess premium plans and other plans, and (B) the actual distribution of such enrolled families among such plans. The amount of the credit under this section in the second succeeding year shall be reduced (or increased, respectively) by the amount of such excess (or deficit) in the total of such payments made by the alliance to all such plans. (c) Per Capita Excess Premium Amount. The per capita excess premium amount, for a regional alliance for a year, is the amount by which (1) the reduced weighted average accepted bid for the alliance for the year, exceeds (2) the regional alliance per capita target for the alliance for the year.
