Mass. Gen. Laws ch. 176J, § 6
(d) If a carrier files a base rate change under this section and the administrative expense loading component, not including taxes and assessments, increases by more than the most recent calendar year's percentage increase in the New England medical CPI or if a carrier's reported contribution to surplus exceeds 1.9 per cent or if the aggregate medical loss ratio for all plans offered under this chapter is less than the applicable percentage set forth in subsection (e), then such carrier's rate, in addition to being subject to all other provisions of this chapter, shall be presumptively disapproved as excessive by the commissioner as set forth in this subsection; provided, however, that there is an exception for a carrier whose Risk Based Capital Ratio falls below 300 per cent for the most recent 4 consecutive quarters. For such carriers the reported contribution to surplus may not exceed 2.5 per cent.
If, however, a carrier's base rates are presumptively disapproved for failure to meet only the aggregate medical loss ratio threshold of the applicable percentage set forth in subsection (e), then the carrier's base rates shall not be presumptively disapproved as excessive by the commissioner if the carrier's aggregate medical loss ratio for all plans offered under this chapter is not less than 1 per cent greater than the carrier's equivalent medical loss ratio was 12–months prior to the carrier's present rate filing.
If the annual aggregate medical loss ratio for all plans offered under this chapter is less than the applicable percentage set forth in subsection (e), or less than the medical loss ratio that was not presumptively disapproved by the commissioner for being in excess of 1 per cent of the carrier's prior year base rate, over the applicable 12–month period, the carrier shall refund the excess premium to its eligible individuals and eligible small groups. A carrier shall communicate within 30 days to all individuals and small groups that were covered under plans during the relevant 12–month period that such individuals and small groups qualify for a refund to be issued under this paragraph, which may take the form of either a refund on the premium for the applicable 12–month period or, if the individual or groups are still covered by the carrier, a credit on the premium for the subsequent 12–month period. The total of all refunds issued shall equal the amount of a carrier's earned premium that exceeds that amount necessary to achieve a medical loss ratio of the applicable percentage set forth in subsection (e), calculated using data reported by the carrier as prescribed under regulations promulgated by the commissioner. The commissioner may authorize a waiver or adjustment of this requirement only if it is determined that issuing refunds would result in financial impairment for the carrier.
(e) The medical loss ratio set forth in subsection (d) shall be 90 per cent for the period through December 31, 2013. The medical loss ratio set forth in subsection (d) shall be 89 per cent for the period from January 1, 2014 through December 31, 2014. The medical loss ratio set forth in subsection (d) shall be 88 per cent for the period from January 1, 2015 forward.
