How Does Age Affect Medigap Prices in Iowa?

  • How Rates Are Determined:


    • Based on your age. As you get older, the premiums go up. Although they may look less expensive when you are younger, they may become the most expensive as you age.


    • Based on your age when you buy the Medigap plan. The premium rate does not increase as you age.


    • Not based on age. The rate is the same for everyone, regardless of age.

    Both issue-age and community rated premiums may increase in cost over time because of external factors such as inflation, but they will not increase because of a person’s age.
