§ 2330. No fault motor vehicle insurance rates; reflection of reduced exposure to loss. Where the principal operator of a motor vehicle or such operator's spouse is eligible for medicare benefits for items of basic economic loss specified in paragraph one of subsection (a) of section five thousand one hundred two of this chapter, or where the insurer's obligation to pay first party benefits for loss of earnings from work is reduced by virtue of the provisions of such subsection, the premium attributable to coverage under the automobile insurance policy for such items shall be appropriately modified to reflect the insurer's reduced exposure to loss.
