    - (A) **In general—** The monthly beneficiary premium for a [prescription drug plan](/usc/42/1395w–151.md?p=a-14) is the base beneficiary premium computed under paragraph [(2)](#a-2) or [(8)](#a-8) (as applicable) as adjusted under this paragraph.
    - (B) **Adjustment to reflect difference between bid and national average bid—**
      - (i) **Above average bid—** If for a month the amount of the standardized bid amount (as defined in [paragraph (5)](#a-5)) exceeds the amount of the adjusted national average monthly bid amount (as defined in [clause (iii)](#a-1-B-iii)), the base beneficiary premium for the month shall be increased by the amount of such excess.
      - (ii) **Below average bid—** If for a month the amount of the adjusted national average monthly bid amount for the month exceeds the standardized bid amount, the base beneficiary premium for the month shall be decreased by the amount of such excess.
      - (iii) **Adjusted national average monthly bid amount defined—** For purposes of this subparagraph, the term “adjusted national average monthly bid amount” means the national average monthly bid amount computed under [paragraph (4)](#a-4), as adjusted under [section 1395w–115(c)(2) of this title](/usc/42/1395w–115.md?p=c-2).
    - (C) **Increase for supplemental prescription drug benefits—** The base beneficiary premium shall be increased by the portion of the [PDP approved bid](/usc/42/1395w–151.md?p=a-11) that is attributable to supplemental prescription [drug](/usc/42/11851.md?p=4) benefits.
    - (D) **Increase for late enrollment penalty—** The base beneficiary premium shall be increased by the amount of any late enrollment penalty under [subsection (b)](#b).

    - (A) **In general—** For each year (beginning with 2006) the [Secretary](/usc/42/1301.md?p=a-6) shall compute a national average monthly bid amount equal to the average of the standardized bid amounts (as defined in [paragraph (5)](#a-5)) for each [prescription drug plan](/usc/42/1395w–151.md?p=a-14) and for each [MA–PD plan](/usc/42/1395w–151.md?p=a-9) described in [section 1395w–21(a)(2)(A)(i) of this title](/usc/42/1395w–21.md?p=a-2-A-i).

    - (B) **Separate period—** Any period during all of which a [part D eligible individual](/usc/42/1395w–151.md?p=a-4) is entitled to [hospital](/usc/42/300s–3.md?p=1) insurance benefits under part A and—

  - (2) **Crediting of late enrollment penalty—**
    - (A) **Portion attributable to increased actuarial costs—** With respect to late enrollment penalties imposed under [subsection (b)](#b), the [Secretary](/usc/42/1301.md?p=a-6) shall specify the portion of such a penalty that the [Secretary](/usc/42/1301.md?p=a-6) estimates is attributable to increased actuarial costs assumed by the [PDP sponsor](/usc/42/1395w–151.md?p=a-13) or MA organization (and not taken into account through risk adjustment provided under [section 1395w–115(c)(1) of this title](/usc/42/1395w–115.md?p=c-1) or through reinsurance payments under [section 1395w–115(b) of this title](/usc/42/1395w–115.md?p=b)) as a result of such late enrollment.

    - (C) **Collection by plan—** In the case of a late enrollment penalty that is collected from a [part D eligible individual](/usc/42/1395w–151.md?p=a-4) in a manner other than the manner described in [section 1395w–24(d)(2)(A) of this title](/usc/42/1395w–24.md?p=d-2-A), the [Secretary](/usc/42/1301.md?p=a-6) shall establish procedures for reducing payments otherwise made to the [PDP sponsor](/usc/42/1395w–151.md?p=a-13) or MA organization by an amount equal to the amount of such penalty less the portion of such penalty estimated under [subparagraph (A)](#c-2-A).

    - (B) **Agreements—** In the case where the monthly benefit payments of an individual that are withheld under [subparagraph (A)](#c-4-A) are insufficient to pay the amount described in such subparagraph, the Commissioner of [Social](/usc/42/1397j.md?p=20) Security shall enter into agreements with the [Secretary](/usc/42/1301.md?p=a-6), the [Director](/usc/42/11851.md?p=5) of the Office of Personnel Management, and the Railroad Retirement Board as necessary in order to allow other [agencies](/usc/42/1397n–12.md?p=1) to collect the amount described in [subparagraph (A)](#c-4-A) that was not withheld under such subparagraph.
