N.D. Cent. Code § 65-05-10.1
This benefit only applies to claims with a date of first disability or date of successful reapplication occurring after June 30, 1991. For these claims, beginning on the first day of July immediately following the fifth full year of partial disability and every year thereafter, an injured employee who has received a waiver of the five-year cap on partial disability benefits under section 65-05-10 is eligible for a lump sum inflation adjustment. The organization shall calculate the lump sum inflation adjustment under this section on July first of each year by multiplying the previous year's percent increase in the state's average weekly wage, if any, by the total amount of partial disability payments paid to the injured employee in the preceding twelve months, including the preceding year's inflationary adjustment award.
