Minn. Stat. § 65B.491
After August 1, 1987, no plan of reparation security issued to or renewed with a person who has attained the age of 65 years may provide coverage for wage loss reimbursement that the insured will not reasonably be expected to be able to receive. It is the responsibility of the person issuing or renewing the plan to inquire as to the applicability of this section. The rate for any plan for which coverage has been excluded or reduced pursuant to this section must be reduced accordingly. This section does apply to self-insurance.
