Legal name and group as filed with CMS
Commission as a share of premium, by state
The share is the agents' fees and commissions this carrier reported to CMS, divided by the medical premium it earned in that state and market. It counts medical business only, so a carrier's dental, vision, life and disability commissions are not in it, and a carrier that insures no medical business reports no share at all.
The states where this carrier earned the most premium, largest first.
| State | Market | Commission, share of premium | Premium earned |
|---|---|---|---|
| Ohio | large-group | 3.1% | $1,261,730,016 |
| Ohio | small-group | 2.9% | $462,504,906 |
| Ohio | individual | 2.0% | $68,528,268 |

This report covers major medical insurance, in all three markets: individual, small group and large group. A company that only administers self-funded plans files none of it, and neither does one that writes only dental, vision, life or disability coverage, so nothing appears here for them.
Filed rate changes by state
Each row is the average rate change this carrier filed with a state's regulator for 2026. The figure covers a whole block of business, so it is not the change on any one employer's plan.
Ordered by the premium this carrier earned in each state.
| State | Market | Average rate change filed |

| Ohio | small-group | 19.6% |

Rates are filed with regulators for small-group and individual coverage only. Large-group rates are negotiated, so they are not in this file.
