Medicare Supplement Rate Actions - 2025 Q4

The Medicare supplement market continues to experience higher claims and carriers are attempting to mitigate the higher loss ratios by pursuing larger rate increases.  Throughout 2025, rate increases have continued to trend up from 2024 levels.  Now, results through the third quarter are in.

The charts below summarize the average historical rate increases of the most prominent carriers in the Medicare supplement space. This data pertains only to open blocks of business and does not consider instances where companies are implementing large rate decreases as they re-enter the market using old paper. All carriers besides the largest six have been grouped together as “Other”.

Let’s start with Plan G.

Each group continues to show larger rate increases in 2025 than in previous years. The data shows that Aetna and Mutual of Omaha have been pursuing rate increases that are 6% to 10% higher than in 2024.  Alternatively, United Healthcare and Blue Cross Blue Shield average rate increases have increased by less than 2% versus 2024. 

Next up is Plan N.

Here, nearly all groups display larger increases in 2025 than usual.  Again, you can see that some companies show a more gradual reaction to increasing claims trend while some have acted more swiftly.     

For all plans, we expect the trend of higher rate actions to continue into 2026 as carriers continue to pursue improved loss ratios.  Companies that acted quickly would have seen a deterioration in their competitive positioning but should see more rapid improvements in their loss ratios.
