Rate Increase Trends for Plan G

When choosing a Medigap Plan G policy, you’re not just locking in today’s rate; future rate increases are crucial.

Typical Annual Increase

Nationally, average Plan G premiums rise about 3% to 6% annually. However, some states and carriers have seen up to 10% jumps.

Drivers of Increases

  • Age rating: Attained-age plans increase as you age, plus company-wide adjustments.
  • Medical inflation: Rising healthcare costs affect all carriers’ claims expenses.
  • State regulations: Community-rated states (e.g., New York) have higher base premiums but fewer age-related increases.

Historical Examples

  • In the last five years, Mutual of Omaha has averaged around 4% annual increases, making it one of the most stable among major carriers.
  • Aetna and Cigna have had more variable increases (3–8%), depending on local claims experience.
  • UnitedHealthcare often maintains more minor annual adjustments, around 2–4%, offset by higher initial premiums.

How Are Plan G Premiums Set?

Medicare Supplement insurers use three pricing methods:

  1. Community-rated (no age-rated): Everyone pays the same regardless of age.
  2. Issue-age-rated: Premium is based on the age when you first enroll and doesn’t increase due to aging, only due to inflation or company-wide changes.
  3. Attained-age-rated: Premium is based on current age and increases as you get older — the most common method.

Understanding which method is used is vital when planning for long-term affordability.
