As first shared earlier in April, CSG Actuarial has compiled information from the NAIC* and other sources and is reporting that total earned premiums in the Medicare Supplement market in 2024 totaled $39.1 billion, a 6.4% increase over 2023.

Here’s how that 2024 percentage increase in premiums breaks down for the top 10 Medicare Supplement carriers.

As the overall Medicare Supplement market has grown over the past ten years, the distribution of policies by plan has changed significantly over that time.  Plan G has a much larger market share in 2024 than 2015, at the expense of Plan F and others.
