Fed Regist. 1998 Oct 21;63(203):56201-12.
As required by section 1839 of the Social Security Act, this notice announces the monthly actuarial rates for aged (age 65 or over) and disabled (under age 65) enrollees in the Medicare Supplementary Medical Insurance (SMI) program for 1999. It also announces the monthly SMI premium rate to be paid by all enrollees during 1999. The monthly actuarial rates for 1999 are $92.30 for aged enrollees and $103.00 for disabled enrollees. The monthly SMI premium rate for 1999 is $45.50. (The 1998 premium rate was $43.80). The 1999 Part B premium is not equal to 50 percent of the monthly actuarial rate because of the differential between the amount of home health that is transferred into Part B in 1999 (two-sixths) and the amount in Part B that is included in the premium calculation (two-sevenths).
根据《社会保障法》第1839条的要求，本通知公布了1999年医疗保险补充医疗保险（SMI）计划中65岁及以上老年人和65岁以下残疾人参保者的月度精算费率。它还公布了1999年所有参保者需支付的月度SMI保费费率。1999年老年人参保者的月度精算费率为92.30美元，残疾参保者为103.00美元。1999年的月度SMI保费费率为45.50美元。（1998年的保费费率为43.80美元）。由于1999年转入B部分的家庭健康护理金额（六分之二）与保费计算中包含在B部分的金额（七分之二）之间存在差异，1999年B部分保费不等于月度精算费率的50%。
