Medicare Supplement Rate Actions - 2026 Q2 Update
The Medicare supplement market continues to experience higher claims and carriers are attempting to mitigate the higher loss ratios by pursuing larger rate increases. For many carriers, early 2026 average rate increases continued to trend up from 2024 and 2025. Note that 2026 carrier data is through April, therefore the sample size of approved filings for 2026 is still relatively small.
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.
All groups besides Mutual of Omaha show a larger rate increase in 2026 than in previous years. The data shows that Aetna and Mutual of Omaha were ahead of the market with a large jump in increase amounts from 2024 to 2025. Cigna, Humana, and United Healthcare had a smaller jump in 2025, but early data shows a 6 to 8% jump from 2025 to 2026.
Next up is Plan N.
Again, all groups besides Mutual of Omaha display larger increases in 2026 than 2025, although Aetna has leveled off. You can see that some companies have shown a more gradual reaction to increasing claim trends, while others have acted more swiftly.
For all plans, we expect the trend of higher rate actions to continue throughout the rest of 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.
