Ghost Networks: An Industry Problem Hiding in Plain Sight

It's a familiar story. A consumer logs into their health plan portal and finds dozens of "in-network" physicians or therapists nearby. But after a series of calls, the reality sets in: the provider no longer works at that location, isn't accepting new patients, only practices in an inpatient setting, is no longer in-network, or the phone number simply doesn't work. The industry has a name for this phenomenon: ghost networks.

Ghost networks undermine one of the foundational promises of managed care, that members will have meaningful access to in-network providers. And while regulators have acknowledged the problem for years, meaningful improvement remains elusive.

The issue is not new. Between 2016 and 2018, the Centers for Medicare and Medicaid Services (CMS) conducted extensive reviews of Medicare Advantage provider directories and found widespread inaccuracies. Error rates in some markets were significant enough to raise serious questions about network adequacy and consumer protection.

Fast forward to the last two years, and similar investigations at both the federal and state levels have revealed many of the same deficiencies. Despite regulatory reforms, updated guidance, and increased scrutiny, directory accuracy has not materially improved across the industry.

State regulators have authority to fine plans for inaccuracies. Health plans are mandated to validate and update directory information at least every 90 days. Yet enforcement actions are relatively rare compared to the scale of the problem, and penalties, when assessed, often do not create sustained systemic change.

Health plans are mandated to verify and maintain accurate provider data. On paper, the framework is clear:

• Validate provider directory data at least quarterly
• Remove providers who cannot be confirmed
• Update changes in a timely manner
• Ensure network adequacy standards are met

In practice, however, maintaining accurate directories is extraordinarily complex.

Provider data is dynamic. Physicians change practice locations, retire, join hospital systems, leave networks, update panel status, and modify hours of operation. Large health systems may process hundreds of roster changes monthly. When information flows slowly or inconsistently between providers and payers, directory accuracy degrades rapidly.

Internal validation efforts by health plans are labor-intensive and expensive. Staff must call offices, send outreach communications, reconcile conflicting information, and document verification attempts. These activities compete with core operational priorities.

Third-party vendors offer specialized provider data validation services, but health plans often hesitate to invest due to cost considerations, particularly when enforcement risk appears manageable. This reality raises an uncomfortable question:

Is there, in some corners of the industry, a "wait and see" or "catch me if you can" mentality? A willingness to risk regulatory penalties rather than proactively solve the problem?

The Real Victims: Health Plan Members

While regulators debate enforcement strategy and plans weigh operational costs, members ultimately bear the consequences.

Consumers rely on provider directories to make critical healthcare decisions. When information is inaccurate, care is delayed, out-of-network bills accumulate unexpectedly, behavioral health access is obstructed, and trust in the healthcare system erodes.

For individuals seeking urgent behavioral health services, maternity care, or specialist treatment, ghost networks are not an inconvenience. They are a barrier to care.

Consumer frustration is growing. Advocacy organizations are increasingly conducting their own "secret shopper" audits, publicly reporting findings, and drawing media attention to discrepancies. In some cases, these efforts have catalyzed class action litigation alleging deceptive network representations.

Public exposure, rather than regulatory enforcement alone, may ultimately prove to be the more powerful catalyst for change.

A Shared Responsibility, Not a One-Sided Burden

It is tempting to frame this as a payer-only issue. That would be a mistake. Maintaining accurate provider directories requires shared accountability between health plans and providers. However, from a regulatory perspective, it is the health plan that is typically accountable for their contracted network provider behaviors.

The key elements of a sustainable solution include:

1. Timely Provider-to-Plan Data Exchange:

Large provider organizations must proactively notify contracted plans of roster changes, including additions, terminations, panel status updates, and location changes, on a scheduled and standardized basis.

2. Prompt Plan-Side Updates:

Health plans must ingest and apply these changes without delay, supported by disciplined operational workflows.

3. Routine Reconciliation Protocols:

Periodic data reconciliation between payer and provider systems is essential to ensure alignment and eliminate drift.

4. Technology-Enabled Automation:

Scalable data exchange platforms and structured APIs can dramatically reduce manual verification burden.

5. Governance and Accountability Metrics:

Directory accuracy should be tracked as a core performance indicator tied to executive oversight, not treated as a compliance afterthought.

Beyond Compliance: A Member Experience Imperative

The most compelling motivation to solve ghost networks should not be fear of fines or staying one step ahead of a regulator's effort to find deficiencies. It should be a genuine commitment to member experience and equitable access to care.

Accurate provider directories are foundational to network adequacy integrity, value-based care alignment, prior authorization accuracy, claims processing efficiency, and consumer trust.

In an era where health plans compete on experience, digital engagement, and brand loyalty, inaccurate provider data is a reputational liability.

The healthcare ecosystem increasingly emphasizes transparency. If directories remain unreliable, public scrutiny will intensify. Consumer advocates will continue to document failures. Legal challenges will expand. And frustration will grow.

A Call for Proactive Industry Action

Ghost networks are not an unsolvable technical glitch. They are the predictable result of fragmented data governance and misaligned incentives.

The industry has been acutely aware of this problem for more than a decade. Regulatory investigations dating back to CMS reviews in 2016 and 2018 confirmed it. Recent audits show it persists. The question is no longer whether the issue exists. It is whether stakeholders are willing to address it systematically.

Health plans and providers must jointly:

• Invest in structured, repeatable data exchange processes
• Treat directory accuracy as a strategic priority
• Move from reactive validation to proactive synchronization
• Recognize that members, not regulators, are the ultimate stakeholders

Consumers are watching. Advocates are organizing. Transparency is increasing. Accurate provider directories are not merely a compliance requirement. They are a promise to members and patients.

The time has come for the industry to keep that promise.
