Exhibit 3. Ratio of Adjusted Mean Plan Liability of LIS to Non-LIS by Risk Decile Using Alternative Risk Adjustment Approaches.

Exhibit 3

Note: This exhibit displays the plan liability ratios and 95% confidence intervals for LIS to non-LIS beneficiaries for each risk decile. The top panel uses risk deciles based on RxHCC scores and prior year drug use information (48 therapeutic class indicators); the bottom panel uses risk deciles based on RxHCC scores and prior year drug costs. The dotted lines represent the current LIS multipliers of 1.08 (full) and 1.05 (partial), respectively.
