§ 406.32 Monthly premiums.
(a) Promulgation and effective date. Beginning with 1984, premiums are promulgated each September, effective for the succeeding calendar year.
(b) Monthly premiums: Determination of dollar amount. (1) Effective for calendar years beginning January 1989, the dollar amount is determined based on an estimate of one-twelfth of the average per capita costs for benefits and administrative costs that will be payable with respect to individuals age 65 or over from the Federal Hospital Insurance Trust Fund during the succeeding calendar year.
(2) Before 1989, the dollar amount was determined by multiplying $33 by the ratio of the next year's inpatient deductible to $76, which was the inpatient deductible determined for 1973. (Because of cost controls, the deductible actually charged for that year was $72.)
