Women’s Health Insurance Coverage

Health insurance coverage is an important factor in making health care affordable and accessible to women.1 Women with health coverage are more likely to obtain needed preventive, primary, and specialty care services, and have better access to new advances in women’s health. Among the 97.5 million women ages 19 to 64 residing in the U.S., most had some form of coverage in 2023. Over the past decade, the Affordable Care Act (ACA) has expanded access to affordable coverage through a combination of Medicaid expansions, private insurance reforms, and premium tax credits. However, while the uninsured rate has declined significantly in the past decade, gaps in private sector coverage, enrollment and eligibility barriers in publicly-funded programs, and persistent affordability challenges have left one in ten women uninsured. This factsheet reviews major sources of coverage for women residing in the U.S. in 2023, discusses the impact of the ACA on women’s coverage, and the coverage challenges that many women continue to face.

Sources of Health Insurance Coverage

Employer-Sponsored Insurance

Approximately 58.6 million women ages 19-64 (60%) received their health coverage from employer-sponsored insurance in 2023 (Figure 1).2

Non-Group Insurance

The ACA expanded access to the non-group or individually purchased insurance market by offering premium tax credits to help individuals afford coverage purchase through state-based health insurance Marketplaces. It also included many insurance reforms to alleviate some of the long-standing barriers to coverage (such as gender rating, lack of maternity coverage, and pre-existing conditions having a disproportionate effect on women) in the non-group insurance market. In 2023, about 9% of women ages 19 to 64 (approximately 8.4 million women) and 8% of their male counterparts purchased insurance in the non-group market.4 This includes individuals who purchased private policies from the ACA Marketplace in their state, as well as those who purchased coverage from private insurers that operate outside of Marketplaces.

Medicaid

The state-federal program for individuals with low-incomes, Medicaid, covered 19% of adult women ages 19 to 64 in 2023, compared to 14% of men. Historically, to qualify for Medicaid, women had to have very low incomes and be in one of Medicaid’s eligibility categories: pregnant, mothers of children 18 and younger, a person with a disability, or over 65. Women who didn’t fall into these categories typically were not eligible regardless of how poor they were. The ACA allowed states to broaden Medicaid eligibility to most individuals with incomes less than 138% of the FPL regardless of their family or disability status, effective January 2014. As of December 2024, 40 states and DC have expanded their Medicaid programs under the ACA.

Uninsured

On average, women have lower incomes and have been more likely to qualify for Medicaid than men under one of Medicaid’s eligibility categories; pregnant, parent of children under 18, disabled, or over 65. As a result, women are more likely than men to qualify for Medicaid and less likely to be uninsured. In 2023, 13% of men ages 19-64 were uninsured compared to approximately 10% of women in the same age bracket (9.3 million women).

Uninsured women often have inadequate access to care, get a lower standard of care when they are in the health system, and have poorer health outcomes. Compared to women with insurance, uninsured women have lower use of important preventive services such as mammograms, Pap tests, and timely blood pressure checks. They are also less likely to report having a regular doctor.

Scope of Coverage and Affordability

The ACA set national standards for the scope of benefits offered in private plans. In addition to the broad categories of essential health benefits (EHBs) offered by marketplace plans, all privately purchased plans must cover maternity care which had been historically excluded from most individually purchased plans. In addition, most private plans must cover preventive services without co-payments or other cost sharing. This includes screenings for breast and cervical cancers, well woman visits (including prenatal visits), prescribed contraceptives, breastfeeding supplies and supports such as breast pumps, and several STI services. There have been several legal challenges over elements of the preventive services policy, including in the pending case, Braidwood Management Inc. v. Becerra, which could affect whether the preventive services requirement remains intact in the future. Twenty-five states have laws banning coverage of most abortions from the plans available through the state Marketplaces. These restrictions were in place prior to the Supreme Court’s decision to overturn Roe v Wade.

Affordability of coverage continues to be a significant concern for many women, both for those who are uninsured as well as those with coverage. The leading reason why uninsured adults report that they haven’t obtained coverage is that it is too expensive. Under employer-sponsored insurance, the major source of coverage for women, 60% of all covered workers with a general annual deductible have deductibles of at least $1,000 for single coverage. Thirty-seven percent of women with employer sponsored coverage report that it is difficult to meet their deductibles.8
