The commissioner of insurance shall annually determine a base premium rate discount of at least 14 per cent for the reduced or selective or tiered network plan compared to the base premium of the carrier's most actuarially similar plan with the carrier's non-selective or non-tiered network of providers. The savings may be achieved by means including, but not limited to: (i) the exclusion of providers with similar or lower quality based on the standard quality measure set with higher health status adjusted total medical expenses or relative prices, as determined under section 10 of chapter 12C; or (ii) increased member cost-sharing for members who utilize providers for non-emergency services with similar or lower quality based on the standard quality measure set and with higher health status adjusted total medical expenses or relative prices, as determined under said section 10 of said chapter 12C.
The commissioner may apply waivers to the base premium rate discount determined by the commissioner under this section to carriers who receive 80 per cent or more of their incomes from government programs or which have service areas which do not include either Suffolk or Middlesex counties and who were first admitted to do business by the division of insurance on January 1, 1986, as health maintenance organizations under chapter 176G.
The commissioner shall promulgate regulations requiring the uniform reporting of tiering information, including, but not limited to, requiring at least 90 days before the proposed effective date of any tiered network plan or any modification in the tiering methodology for any existing tiered network plan, the reporting of a detailed description of the methodology used for tiering providers, including: the statistical basis for tiering; a list of providers to be tiered at each member cost-sharing level; a description of how the methodology and resulting tiers will be communicated to each network provider, eligible individuals and small groups; and a description of the appeals process a provider may pursue to challenge the assigned tier level.
