A recent federal watchdog report has raised serious questions about the accessibility of mental health care under private Medicare and Medicaid insurance plans, revealing that many patients may be facing “ghost networks” of providers that exist more on paper than in practice.
According to the Office of Inspector General (OIG) for the Department of Health and Human Services, which oversees the nation’s massive Medicare and Medicaid programs, numerous insurers inaccurately list mental health professionals—psychiatrists, psychologists, and therapists—as available to treat plan members. In reality, many of these professionals either do not have contracts with the plans, are no longer working at the locations listed, or have retired entirely.
The report focused on Medicare Advantage plans and privately managed Medicaid programs, which together cover roughly 30% of all Americans and involve hundreds of billions of federal dollars annually. These insurers receive fixed payments per enrollee and are expected to maintain adequate networks of providers to ensure timely access to care. Yet the findings show a significant gap between expectation and reality.
The OIG discovered that 55% of mental health professionals listed as in-network by Medicare Advantage plans were not actually providing care to plan members. For Medicaid managed care plans, the figure stood at 28%. Investigators found cases in which a provider was listed at multiple practice locations, only for investigators to learn the individual had retired years ago.
Patients are feeling the impact firsthand. Jeanine Simpkins of Mesa, Arizona, experienced the challenge when a 40-year-old family member required mental health care. The family’s Medicare Advantage plan listed numerous rehab facilities, yet when Simpkins called about 20 programs, none could accept her relative due to insurance restrictions. The patient ultimately enrolled in part-time hospital care instead of an inpatient rehabilitation program.
The consequences of these phantom networks are particularly acute for those seeking mental health care. Jodi Nudelman, a regional inspector general who helped author the report, highlighted the vulnerability of these patients. “Acknowledging a need for mental health care is already difficult for many people,” she said. “Any roadblock—like inaccurate provider listings—can discourage patients from seeking help when they most need it.”
The report examined a sample of 10 counties across five states—Arizona, Iowa, Ohio, Oregon, and Tennessee—including both urban and rural areas. Forty Medicare Advantage plans and 20 Medicaid managed care plans were analyzed. While the OIG did not disclose specific insurers, the findings suggest that misleading provider directories may be a widespread issue.
Industry representatives acknowledged the challenges but emphasized ongoing efforts to improve access. Susan Reilly, vice president of communications for the Better Medicare Alliance, noted, “While this report covers a small sample of plans, we agree there is more work to do. Managed care companies remain committed to improving access and ensuring accurate provider networks for our members, working closely with policymakers and regulators.”
To address the problem, the OIG recommends that government administrators make better use of medical billing data to verify whether listed providers are actively seeing patients. Additionally, the watchdogs urge the creation of a national, searchable directory of mental health providers, detailing which Medicare and Medicaid plans each professional accepts. Such a resource would help patients find reliable care quickly and enable regulators to hold insurers accountable for their network claims.
Federal administrators overseeing Medicare and Medicaid have already begun steps toward building such a directory, and managed care companies have expressed support for the initiative. However, the report underscores a persistent disconnect between the promise of mental health coverage and the reality on the ground, leaving many Americans at risk of inadequate care despite being technically “covered.”
In an era where mental health needs are rapidly growing, the watchdogs’ findings serve as a stark reminder: having insurance does not always guarantee access to care. Without proper oversight and accurate information, patients may find themselves navigating networks that exist only on paper, not in practice.
