Payer Overview

Caresource Group operates as a leading regional health insurer with a concentrated but significant national footprint. The company is the #17 largest US A&H payer by premium and writes $11.97B in the US market, representing a 0.83% US market share across 7 states. The organization reports an Estimated Total Members base of 1.7M and operates through 7 affiliated subsidiaries, reflecting a structure that supports both scale and local market focus.

Caresource Group's strongest positions are clustered in a handful of Midwestern and adjacent states, which helps explain why a large share of its premium and membership is geographically concentrated rather than evenly spread across the country. This concentrated footprint suggests the payer prioritizes depth in select state markets rather than broad national retail penetration.

Premium by Scope

Caresource Group's premium is entirely concentrated in the US States & DC scope according to the authoritative data provided. The payer does not report premium in US territories or foreign jurisdictions, so its footprint is exclusively U.S. mainland. For providers, this concentration means negotiations and network strategies can be focused on a limited set of states where the payer controls most of its commercial and government business.

Caresource Group's premium is highly concentrated, with $8.60B written in Ohio alone and the national total at $11.97B. This concentration means that national contracting levers will be disproportionately influenced by the payer's relationships and rate structures in Ohio and the neighboring Midwestern states. Providers negotiating with Caresource Group should prioritize engagement in Ohio and Indiana, where scale is largest, while maintaining targeted strategies in Georgia and West Virginia to capture regional opportunities.

The membership distribution mirrors premium concentration, with 1.17M estimated members in Ohio accounting for the bulk of the payer's membership book. For health systems and multi-state provider groups, this geographic concentration simplifies network strategy by focusing operational and contracting resources on a limited set of high-impact states rather than a wide, dispersed national footprint.

State-by-State Market Position

Caresource Group shows its strongest presence in the Midwest, led by Ohio and Indiana, which together account for the majority of premium and membership. The Southeast presence is more modest but notable in Georgia, while Appalachia exposure comes through West Virginia and Kentucky. There is minimal presence in the Carolinas and Arkansas.

For multi-state provider groups, the distribution suggests prioritizing negotiations and integration efforts in the Midwest and selected adjacent states. The payer's top-ranked state is Ohio, so statewide contracting outcomes there will have outsized effects on overall financial performance and network adequacy. Smaller footprints in states like North Carolina and Arkansas mean less bargaining power locally, so providers should tailor approaches by state scale and competitive dynamics.

Estimated Member Demographics

Nationally, the largest age bands are 6–18 (271,848 members), 55–64 (247,148 members), and 45–54 (237,632 members), indicating a strong presence among children, adolescents, and pre-seniors. Ohio, as the dominant state, mirrors this distribution, with the highest counts in these age bands. States like Georgia and Indiana also show substantial numbers across all age groups, while smaller states such as North Carolina and Arkansas have much lower member counts.

There is no state with a pronounced skew toward older age bands; most states follow the national pattern, with the largest segments in children and working-age adults. This suggests CARESOURCE GRP's membership is primarily composed of families and individuals in Medicaid and Marketplace populations, with relatively fewer seniors compared to commercial or Medicare-focused payers.

Estimated Members by State

CARESOURCE GRP's estimated member distribution is highly concentrated in Ohio, with 1,168,767 members, accounting for the vast majority of the payer's national membership. Georgia (246,666 members) and Indiana (218,740 members) are the next largest states, followed by West Virginia (29,576), Kentucky (19,923), Arkansas (15,249), and North Carolina (5,436). This geographic concentration aligns closely with the payer's market share and premium volume, with Ohio being both the largest by premium and membership.

The alignment between member counts and market share rank is strong in Ohio, where CARESOURCE GRP holds a 14.24% market share and ranks third. In other states, such as Georgia and Indiana, the member counts are substantial but the market share is lower, reflecting broader market competition. For providers, this means that contracting strategies and care delivery models should be tailored to Ohio's dominant presence, while also considering the unique needs and market dynamics in Georgia and Indiana. The smaller member populations in other states may offer niche opportunities but are less likely to drive significant volume or network leverage.
