Since CY 2003, MCOs are able to use their adjusted excess to reduce the Medicare Part B premium for beneficiaries. When offering this benefit, a plan cannot reduce its payment by more than 125 percent of the Medicare Part B premium. In order to calculate the Part B premium reduction amount, the PBP system must multiply the number entered in the "indicate your MCO plan payment reduction amount, per member" field by 80 percent. The resulting number is the Part B premium reduction amount for each member in that particular plan (rounded to the nearest multiple of 10 cents).
