Purchase Report

Industry Summary

The 1,100 heath and medical insurance carriers offer financial protection against medical expenses by pooling risks and providing coverage for healthcare services in exchange for premium payments. Most Americans have health insurance coverage through private employer-sponsored plans. Individuals may purchase coverage directly from an insurance company or through federal or state marketplaces. Federal and state governments contract with private insurance carriers to offer Medicare (for adults age 65+ and the disabled) and Medicaid (for low-income and disabled individuals) policies.

Underwriting Risk

Profitability for healthcare insurance companies is directly related to an ability to predict, price for, and effectively manage medical costs.

Highly Regulated

The regulatory environment in the health and medical insurance industry is complex and involves a myriad of federal, state, and local requirements that impact operations and profitability.


Recent Developments

Aug 19, 2025 - Reconciliation Bill Could Force Rural Hospital Closures
  • About 300 rural hospitals face possible closure due to Medicaid cuts in the 2025 budget reconciliation bill, according to an analysis by the Cecil G. Scheps Center. More than 20% of Americans live in rural areas where Medicaid covers 1 in 4 adults, per non-profit KFF, and those hospitals have long operated on thin margins as Medicaid increasingly fails to cover their costs. The American Hospital Association says that in 2023 rural hospitals already received $28 billion less from Medicaid than the cost to treat patients. The reconciliation bill cuts a program that helps states fund Medicaid payments to healthcare providers, and despite a provision that offers up to $50 billion for five years to offset the cuts, rural hospitals have sounded the alarm that it is not enough. About 36 states will lose $1 billion or more in rural hospital Medicaid funding because of the bill, according to KKR.
  • The uninsured rate for health coverage in the US is around 8.2%, or about 27 million people (per the Kaiser Family Foundation), a number that could grow by more than 10 million this year from the controversial reconciliation package passed by Congress in mid-2025. The Congressional Budget Office’s (CBO) analysis of the reconciliation bill, part of which makes changes to Medicaid eligibility, found it will significantly increase the number of uninsured Americans. It will boost uninsured rates by 3% or higher in about 16 states, per the CBO, with the biggest jumps expected in California, Florida, Texas, New York, and Illinois. Also problematic is the health insurance tax credits under the Affordable Care Act scheduled to expire at the end of the year, which the CBO estimates could cause the number of uninsured Americans could go as high as 26 million and force up uninsured rates in 35 states.
  • Health and medical insurance industry sales grew 10% over the year prior to $3.1 billion in 2024, according to the Bureau of Labor Statistics, driven by a boost in enrollment in insurance Marketplaces. Health insurance bought through the Affordable Care Act’s Marketplaces rose 31% in 2024 to cover a total of 21.4 million people. The bump largely comes from customers buying Marketplace coverage after a COVID-era rule requiring states to keep Medicare patients in the exchanges, even if they would have been disenrolled due to eligibility, ended in early 2023. Lower-income customers drove the gains (they were most likely to be disenrolled from Medicaid), with a 54% rise in enrollment among applicants with household incomes between 100% to 150% of the US poverty level. In addition, Medicare Advantage is growing in popularity with 31 million seniors enrolled in the program, helping to boost overall industry revenue.
  • The use of AI to screen health insurance claims and potentially deny coverage is coming under increased scrutiny and some US states are responding with new laws to limit its use. Insurance companies are keen to bring costs down using AI in a system where a third of every dollar spent on healthcare goes to administrative costs. Providers, however, are worried that inaccuracies and biases in AI technology will result in erroneous denials. In early 2025 California passed the Physicians Make Decisions Act, which ensures licensed healthcare providers make the final decision on medical treatment instead of AI and technology programs. Similar laws requiring insurance companies to disclose to patients and providers when they are using AI are being considered in Georgia, New York, Oklahoma, and Pennsylvania.
