This report presents trends in enrollment in Medicare Supplement (Medigap) insurance coverage, using data on the numbers of policies in force as of December 2010 from the National Association of Insurance Commissioners (NAIC) and an America’s Health Insurance Plans (AHIP) survey of newly purchased policies issued by Medigap carriers through the first quarter of 2011. The NAIC dataset contains information on most Medigap policies in force in the U.S.,1 representing approximately 9.7 million covered lives as of December 2010, with policies from 250 carriers. Respondents to the AHIP survey of newly purchased policies included large nationwide carriers, single-state plans, and commercial carriers, representing about 52 percent of Medigap enrollment.
