42 U.S.C. § 1395r (THE PUBLIC HEALTH AND WELFARE)
§ 1395r. Amount of premiums for individuals enrolled under this part
(a) Determination of monthly actuarial rates and premiums
(1) The Secretary shall, during September of 1983 and of each year thereafter, determine the monthly actuarial rate for enrollees age 65 and over which shall be applicable for the succeeding calendar year. Such actuarial rate shall be the amount the Secretary estimates to be necessary so that the aggregate amount for such calendar year with respect to those enrollees age 65 and older will equal one-half of the total of the benefits and administrative costs which he estimates will be payable from the Federal Supplementary Medical Insurance Trust Fund for services performed and related administrative costs incurred in such calendar year with respect to such enrollees. In calculating the monthly actuarial rate, the Secretary shall include an appropriate amount for a contingency margin. In applying this paragraph there shall not be taken into account additional payments under section 1395w–4(o) of this title and section 1395w–23(l)(3) of this title and the Government contribution under section 1395w(a)(3) of this title.
(2) The monthly premium of each individual enrolled under this part for each month after December 1983 shall be the amount determined under paragraph (3), adjusted as required in accordance with subsections (b), (c), (f), and (i) of this section, and to reflect any credit provided under section 1395w–24(b)(1)(C)(ii)(III) of this title.
(3) The Secretary, during September of each year, shall determine and promulgate a monthly premium rate for the succeeding calendar year that (except as provided in subsection (g) of this section) is equal to 50 percent of the monthly actuarial rate for enrollees age 65 and over, determined according to paragraph (1), for that succeeding calendar year. Whenever the Secretary promulgates the dollar amount which shall be applicable as the monthly premium rate for any period, he shall, at the time such promulgation is announced, issue a public statement setting forth the actuarial assumptions and bases employed by him in arriving at the amount of an adequate actuarial rate for enrollees age 65 and older as provided in paragraph (1).
(4) The Secretary shall also, during September of 1983 and of each year thereafter, determine the monthly actuarial rate for disabled enrollees under age 65 which shall be applicable for the succeeding calendar year. Such actuarial rate shall be the amount the Secretary estimates to be necessary so that the aggregate amount for such calendar year with respect to disabled enrollees under age 65 will equal one-half of the total of the benefits and administrative costs which he estimates will be payable from the Federal Supplementary Medical Insurance Trust Fund for services performed and related administrative costs incurred in such calendar year with respect to such enrollees. In calculating the monthly actuarial rate under this paragraph, the Secretary shall include an appropriate amount for a contingency margin.
(b) Increase in monthly premium
In the case of an individual whose coverage period began pursuant to an enrollment after his initial enrollment period (determined pursuant to subsection (c) or (d) of section 1395p of this title) and not pursuant to a special enrollment period under subsection (i)(4) or (l) of section 1395p of this title, the monthly premium determined under subsection (a) of this section (without regard to any adjustment under subsection (i) of this section) shall be increased by 10 percent of the monthly premium so determined for each full 12 months (in the same continuous period of eligibility) in which he could have been but was not enrolled. For purposes of the preceding sentence, there shall be taken into account (1) the months which elapsed between the close of his initial enrollment period and the close of the enrollment period in which he enrolled, plus (in the case of an individual who reenrolls) (2) the months which elapsed between the date of termination of a previous coverage period and the close of the enrollment period in which he reenrolled, but there shall not be taken into account months for which the individual can demonstrate that the individual was enrolled in a group health plan described in section 1395y(b)(1)(A)(v) of this title by reason of the individual’s (or the individual’s spouse’s) current employment status or months during which the individual has not attained the age of 65 and for which the individual can demonstrate that the individual was enrolled in a large group health plan (as that term is defined in section 1395y(b)(1)(B)(iii) of this title) by reason of the individual’s current employment status (or the current employment status of a family member of the individual) or months for which the individual can demonstrate that the individual was an individual described in section 1395p(k)(3) of this title. Any increase in an individual’s monthly premium under the first sentence of this subsection with respect to a particular continuous period of eligibility shall not be applicable with respect to any other continuous period of eligibility which such individual may have. No increase in the premium shall be effected for a month in the case of an individual who enrolls under this part during 2001, 2002, 2003, or 2004 and who demonstrates to the Secretary before December 31, 2004, that the individual is a covered beneficiary (as defined in section 1072(5) of title 10). The Secretary of Health and Human Services shall consult with the Secretary of Defense in identifying individuals described in the previous sentence.
(c) Premiums rounded to nearest multiple of ten cents
If any monthly premium determined under the foregoing provisions of this section is not a multiple of 10 cents, such premium shall be rounded to the nearest multiple of 10 cents.
(d) “Continuous period of eligibility” defined
For purposes of subsection (b) of this section (and section 1395p(g)(1) of this title), an individual’s “continuous period of eligibility” is the period beginning with the first day on which he is eligible to enroll under section 1395o of this title and ending with his death; except that any period during all of which an individual satisfied paragraph (1) of section 1395o of this title and which terminated in or before the month preceding the month in which he attained age 65 shall be a separate “continuous period of eligibility” with respect to such individual (and each such period which terminates shall be deemed not to have existed for purposes of subsequently applying this section).
(e) State payment of part B late enrollment premium increases
(1) Upon the request of a State (or any appropriate State or local governmental entity specified by the Secretary), the Secretary may enter into an agreement with the State (or such entity) under which the State (or such entity) agrees to pay on a quarterly or other periodic basis to the Secretary (to be deposited in the Treasury to the credit of the Federal Supplementary Medical Insurance Trust Fund) an amount equal to the amount of the part B late enrollment premium increases with respect to the premiums for eligible individuals (as defined in paragraph (3)(A)).
(2) No part B late enrollment premium increase shall apply to an eligible individual for premiums for months for which the amount of such an increase is payable under an agreement under paragraph (1).
(3) In this subsection:
(A) The term “eligible individual” means an individual who is enrolled under this part B and who is within a class of individuals specified in the agreement under paragraph (1).
(B) The term “part B late enrollment premium increase” means any increase in a premium as a result of the application of subsection (b) of this section.
(f) Limitation on increase in monthly premium
For any calendar year after 1988, if an individual is entitled to monthly benefits under section 402 or 423 of this title or to a monthly annuity under section 3(a), 4(a), or 4(f) of the Railroad Retirement Act of 1974 [45 U.S.C. 231b(a), 231c(a), (f)] for November and December of the preceding year, if the monthly premium of the individual under this section for December and for January is deducted from those benefits under section 1395s(a)(1) of this title or section 1395s(b)(1) of this title, and if the amount of the individual’s premium is not adjusted for such January under subsection (i) of this section, the monthly premium otherwise determined under this section for an individual for that year shall not be increased, pursuant to this subsection, to the extent that such increase would reduce the amount of benefits payable to that individual for that December below the amount of benefits payable to that individual for that November (after the deduction of the premium under this section). For purposes of this subsection, retroactive adjustments or payments and deductions on account of work shall not be taken into account in determining the monthly benefits to which an individual is entitled under section 402 or 423 of this title or under the Railroad Retirement Act of 1974 [45 U.S.C. 231 et seq.].
(g) Exclusions from estimate of benefits and administrative costs
In estimating the benefits and administrative costs which will be payable from the Federal Supplementary Medical Insurance Trust Fund for a year for purposes of determining the monthly premium rate under subsection (a)(3) of this section, the Secretary shall exclude an estimate of any benefits and administrative costs attributable to—
