Physicians Mutual Group Market Analysis: Market Share and Coverage by State

Payer Overview

Physicians Mutual Group is a national health insurer operating as the #104 ranked US A&H payer by premium, writing $583M in the US and holding a 0.04% US market share across 44 states. The company maintains an estimated 93.9K members and operates through 3 affiliated subsidiaries, positioning it as a regional specialist with pockets of concentrated market power rather than a nationwide dominant carrier.

This footprint is concentrated in select Midwestern and Plains states where the carrier registers meaningful state-level shares, while many states show much smaller exposures. That pattern creates opportunities and risks for provider contracting: negotiated rates and network participation will matter most in states where Physicians Mutual Group is concentrated, and multi-state systems should prioritize engagement in those markets.

Premium by Scope

Physicians Mutual Group's premium is exclusively within the US States & DC scope per the provided data, with $583M reported in that scope and no recorded premiums in US territories or foreign jurisdictions. This concentration implies that the payer's business and network leverage are focused on the continental U.S. and nearby states reported, so providers negotiating with Physicians Mutual Group should prioritize U.S. state-level contracting dynamics rather than territory or international exposure.

Physicians Mutual Group shows concentrated premium and membership in select Midwestern and Plains states, most notably WI ($116M, 19.2K members), TX ($71.0M, 9.71K members), AZ ($51.3M, 11.4K members) and IA ($18.0M, 2.71K members). Overall premium exposure totals $583M across the reported states with 93.9K estimated members. This concentration suggests provider contracting leverage will be strongest in states where the carrier holds the largest shares, and network strategies should reflect those regional priorities.

Geographically, the carrier's largest presences are in the Midwest and Plains with meaningful footprints in the South and West as well. For national provider groups, aligning negotiation efforts in WI, TX, AZ, and NE will capture the bulk of the payer's membership and premium influence.

The Affordable Care Act (ACA) established federally-facilitated health insurance marketplaces ("exchanges") where individuals and small businesses can shop for and enroll in health plans, often with income-based subsidies. Issuers that participate in these marketplaces are required to report enrollment, claims, and denial data to CMS (Centers for Medicare & Medicaid Services) each year.

The sections below cover this payer's ACA marketplace-specific footprint — enrollment, plan portfolio, and claims/denial-rate data. This is a narrower, separate population from the NAIC-based commercial data shown earlier on this page (total premium, market share, and membership across all lines of business): ACA marketplace enrollment is typically a small fraction of a payer's total commercial book, and the two datasets should not be treated as equivalent. CMS claims-transparency reporting has also been inconsistent industry-wide since 2020 — many issuers have little or no data for 2021 onward, so a single reporting year is common and does not necessarily indicate anything about the payer's current ACA presence.

Estimated Member Demographics

PHYSICIANS MUT GRP is estimated to cover 88,594 members nationally, based on Census and NAIC market share data. The table below details the estimated member count by age band:

The largest age band is 6-18, representing over 14,000 members, followed by the 35-44, 45-54, and 55-64 bands, each with over 12,000 members. This distribution indicates a payer population with significant pediatric and middle-aged adult representation, with a moderate senior presence.

Providers can expect a balanced mix of care needs, from pediatric preventive services and adolescent health to adult chronic disease management and some geriatric care. The relatively even spread across age bands suggests that PHYSICIANS MUT GRP's covered population will utilize a wide range of healthcare services, requiring providers to maintain comprehensive service offerings.
