The financial health of health insurers is a complex picture, shaped by enrollment trends across different markets and the evolving landscape of government subsidies. As 2024 unfolds, insurers are navigating a system where the flow of premiums and federal funding is undergoing significant shifts, particularly in the individual market following the expiration of temporary Affordable Care Act (ACA) expansions at the conclude of 2025. Understanding these dynamics – across individual, group, Medicaid managed care, and Medicare Advantage plans – is crucial for assessing the stability of the health insurance system and its impact on access to care. This analysis of health insurer financial performance in 2024 reveals a sector adapting to new realities, with implications for both consumers and the broader healthcare economy.
The individual health insurance market, encompassing both ACA Marketplace plans and off-exchange coverage, remains a key area of focus. Insurers in this sector receive payments directly from enrollees, supplemented by federal subsidies for those eligible through the Marketplaces. These subsidies are designed to lower monthly premiums, but their availability and amount have fluctuated in recent years. The expiration of temporary ACA subsidy expansions on December 31, 2025, has reverted eligibility and benefit levels to those originally outlined in the 2010 law, potentially leading to higher premiums for some individuals in 2026. Some plans submitting data on the Exhibit of Premiums Enrollment and Utilization appear to be including some Children’s Health Insurance Program (CHIP) data in their Individual market filings, adding a layer of complexity to the analysis.
The Shift in the Group Market
Even as the individual market often receives the most attention, the fully insured group market – serving employers and their employees – represents a substantial portion of the health insurance landscape. Approximately 25 million people are covered through these plans in 2024. However, it’s important to note that this market excludes the growing number of employer-sponsored plans that are self-funded, which now cover 63% of workers with employer-sponsored insurance, according to a Kaiser Family Foundation (KFF) survey. Plans in the fully insured group market receive premium payments from both employers and employees, creating a different financial dynamic than the individual market.
Medicaid Managed Care: A Growing Segment
Medicaid managed care is another significant component of the health insurance system, with managed care organizations (MCOs) contracting with state Medicaid programs to deliver care to beneficiaries. As of July 2024, over three-fourths – more than 66 million people – of all Medicaid beneficiaries nationally receive their care through these comprehensive, risk-based MCOs, according to data from the Centers for Medicare & Medicaid Services (CMS). However, the services covered by MCOs can vary considerably across states, and data collection presents challenges. The National Association of Insurance Commissioners (NAIC) data used in some analyses defines “Medicaid” in a specific way, excluding Administrative Services Only (ASO) plans, but potentially including other types of plans like prepaid ambulatory health plans (PAHPs) and Programs of All-Inclusive Care for the Elderly (PACE).
Navigating Data Complexities in Medicaid
Analyzing Medicaid data requires careful consideration of reporting practices. Four states – California, Delaware, New York, and Oregon – have different reporting methods, resulting in potentially incomplete data for those states. KFF further defines comprehensive MCOs as those providing acute care services, and sometimes long-term support, excluding “limited benefit plans” that may be included in some analyses. This highlights the need for nuanced interpretation when assessing the financial performance of insurers in the Medicaid managed care market.
Medicare Advantage: A Dominant Force
The Medicare Advantage market has become a dominant force in Medicare, covering around 33 million beneficiaries in 2024 – more than half of all Medicare enrollees, according to KFF. The federal government provides risk-adjusted payments to these plans, averaging nearly $14,823 per enrollee in 2024, as reported by CMS. These payments cover the cost of benefits under Medicare Parts A and B, as well as supplemental benefits like dental, vision, and hearing care. Some plans also charge enrollees additional premiums.
The financial performance of health insurers in 2024 is therefore a multifaceted story, influenced by enrollment trends, government policies, and the specific characteristics of each market segment. The expiration of ACA subsidies, the growth of self-funded employer plans, the expansion of Medicaid managed care, and the continued rise of Medicare Advantage all contribute to a dynamic and evolving landscape. As insurers adapt to these changes, their financial stability will have a direct impact on the affordability and accessibility of healthcare for millions of Americans.
Looking ahead, continued monitoring of enrollment data, subsidy levels, and payment models will be essential for understanding the long-term financial health of the health insurance industry. The next key checkpoint will be the release of updated enrollment figures for the 2026 ACA Marketplace plans, providing insights into the impact of the subsidy changes.
