Payer Overview

University Hlth Care & Gundersen Lut operates as a regional commercial and government lines payer with a focused but meaningful national position. It is the #67 largest US A&H payer by premium and writes $2.31B in the US, representing a 0.16% US market share across 4 states. The organization reports an Estimated Total Members figure of 379.1K and operates through 4 affiliated subsidiaries.

The payer's footprint is concentrated in the Upper Midwest, with its largest state presence driving most of its activity. This concentration shapes contracting leverage and network strategy: provider groups engaging the payer should expect negotiation dynamics driven by strong regional premium and membership density rather than broad national scale. Data indicates the payer does not report a #1 ranking in any state.

Premium by Scope

University Hlth Care & Gundersen Lut's premium is exclusively reported in the US States & DC scope, accounting for 100.00% of its documented premium. There is no separate US territory or foreign premium reported for this payer, indicating an exclusively domestic mainland footprint. For providers, this concentration means contracting and network strategies should focus on the payer's regional operations within the documented states rather than expecting exposure from territories or international business.

University Hlth Care & Gundersen Lut shows a highly concentrated premium footprint, with $2.17B written in WI alone and a national total of $2.31B. The payer's membership base mirrors premium concentration with 359K estimated members in WI out of 379.1K total members. This concentration indicates significant negotiating leverage in Wisconsin and localized network influence, while presence in IL, MN, and IA is comparatively modest.

For provider contracting, the geographic concentration means that system-wide negotiations should prioritize Wisconsin-market terms and capacity planning. Multi-state provider groups should expect materially different commercial dynamics in WI versus IL, MN, and IA, with WI negotiations likely driving most financial outcomes.

State-by-State Market Position

University Hlth Care & Gundersen Lut's strongest presence is in the Midwest, particularly Wisconsin where it holds its top ranked state position and writes $2.17B in premium. The other Midwestern states in its footprint — Minnesota, Illinois, and Iowa — show much smaller premiums ($51.1M, $82.0M, and $4.08M, respectively) and correspondingly lower market shares.

Because the payer's premium and membership are concentrated in the Midwest, multi-state provider groups operating across broader regions (Northeast, Southeast, West, Southwest) will see limited exposure to this payer outside the Upper Midwest. For regional hospital systems and physician groups in Wisconsin, the payer represents a major counterparty and should be a primary focus for contracting strategy and network inclusion discussions.

Estimated Member Demographics

Nationally, the largest age bands are 6–18 and 55–64, each with over 57,000 members, followed closely by the 35–44 and 45–54 bands. The pediatric segment (Under 6 and 6–18) together accounts for over 82,000 members, indicating a strong family and youth presence. The senior segment (65–74 and 75+) is smaller but still significant, with over 54,000 members combined.

Wisconsin dominates the member distribution, with over 358,000 estimated members, far outpacing other states. The age distribution in Wisconsin closely mirrors the national profile, while smaller states like Iowa and Minnesota have proportionally fewer members across all age bands. No state shows a dramatic skew toward older or younger populations, but the overall mix suggests a balanced need for pediatric, adult, and senior care.

Estimated Members by State

The geographic distribution of estimated members for UNIVERSITY HLTH CARE & GUNDERSEN LUT is highly concentrated in Wisconsin, which accounts for over 358,000 members. This is a direct reflection of the payer's strong market share and premium volume in the state. Illinois and Minnesota follow with 11,835 and 7,969 members respectively, while Iowa has a much smaller footprint with only 612 estimated members.

This member concentration aligns closely with the payer's market share rank and premium written in each state. Wisconsin is the clear anchor market, both in terms of share and member volume, while other states represent secondary or tertiary markets. For providers, this means that contracting strategies and care delivery models should be tailored primarily to the Wisconsin population, with adjustments for the smaller, more dispersed member bases in Illinois, Minnesota, and Iowa. The geographic concentration also suggests that network adequacy and access standards will be most critical in Wisconsin, with less impact in the other states due to their limited member counts.
