N.M. Stat. § 59A-18-25
Where amounts of insurance under group, blanket or other forms of life, annuity or health insurance coverage are now or hereafter limited to specified dollar amounts by any provision of the Insurance Code, the insurer may, with the superintendent's approval and notwithstanding the statutory limit otherwise applicable, increase the dollar amount of coverage in particular policies or contracts as reasonably necessary to offset devaluation of dollar purchasing power because of inflation, and to provide current coverage in amount reasonably related to dollar purchasing power at the time such statutory limit was enacted. The superintendent may promulgate reasonable rules and regulations for effectuation of this section under which the increased amounts of coverage may be applied generally and without approval by the superintendent of increases in each instance.
