Humana Group, Centene Corp Group, and McLaren Health Group round out the top five, each holding significant shares.

    The cumulative market share of the top ten insurers is nearly 90%, indicating a highly concentrated market.

    Direct-Purchase324K7.01%
    TRICARE30.9K0.67%
    CHIP/Subsidized78.5K1.70%

    The majority of Indiana's privately insured population is covered through employer-based plans, accounting for over 70% of the market. Direct-purchase insurance represents a smaller but notable segment, while government programs such as TRICARE and CHIP/Subsidized coverage contribute less than 3% combined.

    Indiana's privately insured population is distributed across all age bands, with the largest segments found in the working-age groups. The presence of CHIP/Subsidized coverage highlights the state's support for children and families who may not have access to employer-based insurance.

    Market Dynamics

    Indiana's health insurance market is characterized by a high degree of concentration, with Elevance Health Inc Group holding the largest share. The top two payers, Elevance Health Inc Group and UnitedHealth Group, together account for over half of the private insurance market. This concentration suggests limited competition among insurers, which may influence plan offerings and pricing.

    Employer-based coverage dominates the insured population, reflecting Indiana's strong employment base and the prevalence of group health benefits. Direct-purchase plans, while available, serve a much smaller portion of the population, indicating that most residents rely on employer-sponsored insurance for their coverage needs.

    The age distribution of the privately insured population shows a broad spread, with significant representation in the 35-64 age bands. This aligns with the working-age demographic, which is most likely to have access to employer-based insurance. Coverage for children and older adults is also present, but at lower levels compared to the prime working-age groups.

    Overall, Indiana's insurance landscape is shaped by a few dominant payers and a population that is primarily insured through employment, with supplemental coverage options available for specific groups such as children and military families.
