About three-quarters of Medicaid beneficiaries are in managed care, under which states pay private health plans a set fee per person to cover care. Recently, Medicaid managed care's improper payment estimate has been...

Veterans Crisis Line: Actions Needed to Better Ensure Effectiveness of Communications with Veterans
Suicides occur among veterans at twice the rate of nonveterans. The Department of Veterans Affairs has named suicide prevention one of its top priorities. To help, VA runs the Veterans Crisis Line, a 24/7 phone, chat, and text service. We testified on crisis line challenges. For example: Staff handle multiple chat and text interactions at once, which can mean less attention for those contacting the...

Fishery Disaster Assistance: Process is Changing, but Challenges Remain to Improve Timeliness and Communication [Reissued with revisions on Jun. 25, 2025]
Disasters like hurricanes and oil spills can affect fisheries and communities and may result in lost revenue or jobs.

We found the agency generally took 3 years to disburse funds for some of the 111 requests it received since 2014. The agency is altering...

NASA completed at least some cybersecurity tasks in each program step for all the...
Coast Guard: Actions Needed to Address Cutter Maintenance and Workforce Challenges
To ensure the safety and security of the U.S. coastline and inland waterways, the Coast Guard relies heavily on a fleet of 241 cutters—vessels 65 feet or greater in length with accommodations for crew to live on board. Due to deferred maintenance and challenges obtaining essential parts, the aging cutter fleet is becoming increasingly unavailable for missions as equipment fails. To make up for these...

Children covered by Medicaid are entitled to a comprehensive set of screening, diagnostic and treatment services. These services help ensure that children's health conditions are found and treated in a timely manner.

Nuclear Waste Cleanup: DOE Needs to Improve Contractor Oversight at the Waste Isolation Pilot Plant
The Waste Isolation Pilot Plant in New Mexico is the nation's only facility for disposal of certain defense-related nuclear waste. It's expected to operate until the 2080s, but much of its important infrastructure is decades old and needs to be repaired or replaced. The Department of Energy tracks the condition of its nuclear waste disposal infrastructure. Its contractor runs the facility's operations. DOE doesn't have...
Medicaid and Children's Health Insurance: Disenrollments After COVID-19 Varied Across States and Populations
States must determine if everyone on the rolls for Medicaid and the Children's Health Insurance Program remain eligible each year. They check paperwork, verify income, and more. During the pandemic, full redeterminations were paused until April 2023. Millions were expected to lose coverage once states resumed those efforts. We found that 27 million people (about one-third) were disenrolled after redeterminations resumed. Disenrollment levels varied by...

Veterans Health: Improvements Needed to Achieve Successful Appointment Scheduling Modernization
The Department of Veterans Affairs schedules tens of millions of health care appointments for veterans each year, using dozens of systems to support appointment scheduling. These complex systems have contributed to delays in providing care. The department has begun efforts to modernize these systems.

Since 1991, the Department of Transportation's Congestion Mitigation and Air Quality Improvement Program has funded transportation projects that aim to reduce vehicle emissions. DOT created a tool for states to evaluate the cost-effectiveness of these projects. We found that DOT hasn't routinely communicated with states about this tool. About a third of the states we surveyed said they were unaware of it. We recommended that...
