Medicare Supplement Insurance pricing methods
Medigap pricing methods are significant because they dictate how your premiums may increase in upcoming years. There are three different pricing methods:
- Attained-age rated: The premium increases as you age.
- Issue-age rated: The premium is based on your age when you buy and it may increase due to inflation and other factors, but not due to your age.
- Community rated: The same premium is charged to all Medigap policyholders.
According to data from the U.S. Department of Health & Human Services (HHS), 82% of Medigap insurance policies issued in Illinois were attained-age rated in 2010. 17% of the policies were issue-age rated.
