Medicaid Ghost Networks: The Plan Gets Paid. Can the Patient Get Care?

Medicaid ghost networks fraud involves a plan knowingly misrepresenting which providers are available to obtain or keep Medicaid payments. The directory offers doctors who have left, will not accept the plan, or cannot take new patients. For someone working in provider relations, network operations or quality management, the gap is between what the plan knows and what it tells members: the provider has reported the problem, but the plan keeps presenting the listing as usable care.

This is a Medicaid managed care problem. The state pays the plan a fixed amount per enrolled member, typically each month. The money can arrive while the member is still trying to find someone who will see them. We call that paying for a network the patient cannot use.

What Must a Medicaid Provider Directory Show?

A Medicaid provider directory must tell members who participates, where to find them and whether they accept new enrollees. That last field makes the difference between a provider’s name and a possible appointment.

The federal directory requirements cover provider names and group affiliations, street addresses, telephone numbers, websites where appropriate, and specialties. They also require information about languages and interpreter services, accommodations for people with physical disabilities, and whether covered services are available through telehealth. A searchable directory must be available electronically, with paper copies on request and a machine-readable version on the plan’s website.

Electronic directories must be updated within 30 calendar days after the plan receives updated provider information.

A provider’s message saying the practice has closed its panel gives the plan something specific to correct. The dated message and the directory version that followed it can show whether the plan kept telling members that the provider would accept them.

Who Signs Off on Network Capacity?

The chief executive officer, chief financial officer, or someone reporting directly to one of them certifies specified plan submissions as accurate, complete and truthful. Those submissions include the documentation on which the state bases its network-adequacy certification. They also include encounter data and data used to set payment rates. A directory problem can therefore reach the people signing the plan’s account of its capacity and finances.

Network adequacy means having enough providers, with the right mix and geographic distribution, to serve the plan’s expected enrollment. The plan must give the state assurances that it can do that. The documentation supporting that assurance carries an executive certification.

The contract and the rules for the period in question determine what the plan promised. States set quantitative network standards.

We examine those duties against the actual state contract and the dates of the submissions.

How Do You Prove a Ghost Network?

We examine whether the plan’s directory matches the appointments members can obtain and the care they receive. Government reviewers have tested those promises through encounter records and calls to practices.

The Directory Against Delivered Care

In its October 2025 behavioral-health review, the HHS Office of Inspector General found that an average of 28% of listed behavioral-health providers in the Medicaid plans analyzed had provided no services to those plans’ enrollees during 2023. That inactivity analysis covered 19 Medicaid managed care plans in ten selected counties.

The review compared network lists with encounter data and then surveyed inactive providers about why they had not seen members. The follow-up questions helped distinguish a provider who had moved or would not accept the insurance from one who remained available.

For a network employee, the useful unit is the provider, plan and period. A listing says the provider is available. An encounter says a service occurred. A response from the practice can explain the gap between them.

The Directory Against an Appointment

The inspector general’s December 2014 Medicaid access report used calls to a sample of 1,800 primary care providers and specialists. It found that slightly more than half could not offer an appointment because they were not participating at the listed location or were not accepting new patients enrolled in the plan.

A National Health Law Program guide, A Guide to Oversight, Transparency, and Accountability in Medicaid Managed Care, published in 2015, explains why secret-shopper surveys add something provider lists cannot: they test new-patient acceptance, appointment waits and the experience of trying to obtain care. The guide also credits more active testing in Ohio and New York with uncovering more network violations. How hard someone looks affects how much failure becomes visible.

Who gets counted matters, too. In a broader insurance example, the New York Attorney General’s EmblemHealth agreement cites a company representative’s testimony in alleging that EmblemHealth excluded unreachable providers from its appointment-survey calculations when it should have included them. In the Attorney General’s account, failed calls disappeared from the score. That makes access look better by leaving out the people members cannot reach.

When Does a False Directory Become a False Claim?

A Medicaid False Claims Act case follows the false representation into a request for government money. For a network case, we connect a practice’s correction request, the directory still showing availability and the certified network submission with the payments that followed.

The insider’s knowledge can show who knew the actual position and why the false representation mattered to the government’s payment decision. What did the plan tell the state it could provide, and what money depended on that undertaking?

This is where network operations and finance meet. The directory, the capacity assurance and the payment records each carry part of the story. We work through that connection with the insider and Medicaid fraud whistleblower lawyers who understand plan contracts and certifications.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.

Aetna’s Alleged Pediatric Network: Boys Assigned to Gynecologists

A former quality management nurse consultant brought a whistleblower case against Aetna Better Health of Pennsylvania over allegedly inaccessible pediatric providers, network representations and continued capitation payments. The complaint described children assigned to doctors who were not contracted with the plan, were dead, practiced out of state or did not see children.

The complaint also alleged that legitimate primary-care panels were full and that the plan assigned overflow children to other specialists as primary-care providers. It alleged that management directed the nurse to report access problems verbally rather than in writing, and that the plan miscategorized network complaints as requests to change doctors or plans.

Those allegations connect the patient-facing failure to what people inside the business allegedly knew and how they reported it. A complaint recategorized as a request to change doctors tells a different story from a complaint that the available doctors cannot see the child.

The government declined to join the case. It ended in March 2022 after an agreement with Aetna Medicaid Administrators.

Why Capitation Keeps the Money Moving

Capitation pays for enrollment and the plan’s undertaking to arrange health care. The payment can continue even when services fail to reach members. The National Health Law Program guide explains the incentive plainly: the less care a plan provides, the more of its payments it retains.

The Aetna complaint alleged both sides of that incentive: inflated provider listings attracted enrollment and monthly payments, while inaccessible doctors spared the plan the cost of healthcare those doctors would otherwise have provided.

A 1999 Harvard Kennedy School report, Controlling Fraud and Abuse in Medicaid: Innovations and Obstacles, identified a basic oversight mistake: confusing fraud committed against managed care plans with fraud committed by the plans themselves. It put the second category plainly:

A plan has a financial reason to challenge a provider’s inflated bill. The report’s point is that the same incentive does not police the plan’s own diversion of money from care. For ghost networks, the question returns to the capacity the plan represented and the money it received on that basis.

When Required Services Were Missing

RiverSpring’s May 2024 settlement required it to pay $10,159,130. The managed long-term care plan received monthly payments averaging between $4,000 and $4,500 per member. It admitted that it either failed to provide qualifying services or failed to maintain adequate documentation of those services while receiving payments to which it was not entitled. The government joined a case started by a whistleblower.

CenterLight’s March 2018 settlement required a $10 million payment. It admitted that 186 adult home residents went without required community-based long-term care services in some months while it collected capitation payments to which it was not entitled.

These cases connect the obligation to deliver or document qualifying care with the monthly payments. They show why someone who understands the service requirement can be as important as someone who understands the payment system.

When a Review Existed Only in the Approval

CareCore’s May 2017 settlement shows how a plan contractor’s false approval can lead to payment. The prior-authorization company admitted approving requests awaiting physician review without new medical information or an independent medical-director review. It represented that the required review had occurred when it knew it had not, and Medicare and Medicaid plans paid claims based on those approvals.

What Network Staff Can Bring Into View

Network employees may know when a practice left, when its panel closed, or when the plan first received a correction. Quality staff may know how access complaints were recorded. Data and finance staff may see how those facts reached a certified submission or a payment file.

We connect dated directory versions and provider communications with network-capacity documentation, executive sign-offs, encounter records and the applicable contract. Keeping the provider, service, population and period aligned gives the comparison meaning. A correction request received before a certification presents a different question from a provider leaving afterward.

The National Health Law Program guide explains that encounter data supports both quality measures and capitation-rate setting. That makes the accuracy of plan-reported care relevant to both the access story and the payment story. The employee who knows why the public list and the internal records disagree can give those records their missing context.

When You Know Who Cannot Take the Appointment

If you know the plan kept promising access after staff reported that providers were unavailable, speak with our whistleblower experts about what happened inside the network. We build the case with you around the false promise, the people who knew and the Medicaid payments, and bring in Medicaid fraud whistleblower lawyers who know managed-care network cases. We stay on your side from the first conversation through the case.
