On September 24, 2008, the National Association of Insurance Commissioners (NAIC) adopted revisions to the NAIC Model Regulation to Implement the NAIC Medicare Supplement Insurance Minimum Standards Model Act. The revised NAIC model regulation includes major changes to Medicare Supplement plans and benefits first approved by the NAIC in March 2007, and authorized by the Medicare Improvements for Patients and Providers Act of 2008 (MIPPA). In addition, the model revisions contain changes required by the Genetic Information Nondiscrimination Act of 2008 (GINA).
