According to the 2016 National Health Interview Survey (NHIS), an estimated 5.6 million uninsured, low-income adults--those ages 19 through 64--had incomes at or below the income threshold for expanded Medicaid eligibility as allowed under the Patient Protection and Affordable Care Act (PPACA). Estimates from this nationally representative survey showed that about 1.9 million of the 5.6 million u

GAO and others have raised concerns about the design of Medicare fee-for-service (FFS) cost-sharing--the portion of costs beneficiaries are responsible for when they receive care. The current cost-sharing design has been largely unchanged since Medicare's enactment in 1965, can be confusing for beneficiaries, and can contribute to overuse of services. Additionally, the design leaves some benefici

A small percentage--about 1 percent--of plan year (PY) 2015 enrollments were potentially improper or fraudulent. These applicants had unresolved inconsistencies related to citizenship, status as a national, lawful presence, or Social Security number (SSN), or received coverage while reportedly deceased, according to GAO's analysis of federally facilitated marketplace (FFM) eligibility and enrollm

GAO found that enrollment in private health insurance plans remained concentrated among a small number of issuers in most states in 2014, including in the newly established exchanges. On average in each state and the District of Columbia, 11 or more issuers participated in each of three types of markets-- individual, small group, and large group--from 2011 through 2014. However, in most states, t

As of 2014, key provisions of the Patient Protection and Affordable Care Act (PPACA) resulted in the establishment of health insurance exchanges in each state and changed how insurers determined health insurance premiums. Individual market consumers generally had access to more health plans in 2015 compared to 2014, and in both years the lowest-cost plans were available through exchanges in most

The Patient Protection and Affordable Care Act (PPACA) requires GAO to study competition and market concentration in the health insurance market. For this study, we examined individual, small group, and large group health insurance markets prior to the implementation of key PPACA provisions that went into effect in 2014 and that could affect competition and market concentration among health insur

GAO previously reported that, in 2012, upward payment adjustments affected the vast majority of hospitals paid under Medicare's inpatient prospective system (IPPS). (See GAO-13-334). For this report, GAO found that, of the 3,455 IPPS hospitals in the prior review, the proportion of hospitals qualifying for at least one of four categories of payment adjustments was higher among nonprofit and gover

The Centers for Medicare & Medicaid Services' (CMS) 2011 report to Congress proposed three options for removing Social Security numbers (SSN) from Medicare cards. One option would truncate the SSN displayed on the card, but beneficiaries and providers would continue to rely on the SSN. The other two options would replace the SSN with a new identifier that would be displayed on the card and either

Most employers continued to offer coverage of MH/SU since MHPAEA was passed. Of the employers that responded to GAO's survey, 96 percent offered coverage of MH/SU for the current plan year and for 2008, before MHPAEA was passed. Approximately 2 percent of employers reported offering coverage for only mental health conditions but not substance use disorders for the current plan year and for 2008.

Medicaid and the Children's Health Insurance Program (CHIP)--two joint federal-state health care programs for low-income families and children--play a critical role in addressing the health care needs of children. In 2008, more than 36 million children in the United States received health care coverage through Medicaid or CHIP. Like all children, children covered by Medicaid and CHIP may have hea
