Ghost networks are health insurance provider directories that contain inaccurate, outdated, or misleading information about participating healthcare providers. They can include physicians who are no longer in-network, are not accepting new patients, have incorrect contact information, or are no longer practicing at the listed location.
These inaccuracies make it harder for patients to find available care, even when their health plan appears to offer an adequate provider network.
Quick answer: A ghost network is an inaccurate health insurance provider directory that makes it difficult for patients to identify and schedule care with in-network providers who are actually available.

Why are ghost networks a problem?
Patients rely on provider directories to make informed healthcare decisions.
When those directories contain inaccurate information, patients may spend hours contacting providers who:
- Are no longer in-network
- Are not accepting new patients
- Have retired or relocated
- Have incorrect phone numbers or addresses
- Do not offer the listed specialty or service
The result is delayed care, increased frustration, and unnecessary administrative work for both patients and healthcare practices.
Ghost networks can also create the impression that a health plan offers more provider access than patients actually experience.
How do ghost networks happen?
Provider information changes frequently.
Practices update:
- Office locations
- Phone numbers
- Accepted insurance plans
- Provider availability
- Practice ownership
- New patient acceptance
- Clinical services
Keeping provider directories accurate requires continuous coordination between insurers, healthcare organizations, and medical practices.
Without frequent updates, directory information can quickly become outdated.
How do ghost networks affect patients?
The biggest impact is delayed access to care.
Patients may spend significant time researching providers only to discover they cannot schedule an appointment.
Ghost networks can lead to:
- Longer wait times
- Delayed treatment
- Confusion about insurance coverage
- Additional out-of-pocket costs
- Greater administrative burden
- Lower patient satisfaction
These challenges can be especially serious for patients seeking time-sensitive or behavioral healthcare services, where provider shortages already limit access.
How do ghost networks affect healthcare providers?
Inaccurate directories also create problems for providers.
Practice staff may spend valuable time answering calls from patients who were directed to the wrong office or mistakenly believe the practice accepts their insurance.
Outdated information can also lead to:
- Missed patient opportunities
- Scheduling inefficiencies
- Increased administrative work
- Patient frustration before the first appointment
- Damage to patient trust
Maintaining accurate provider information helps create a better experience for everyone involved.
What are regulators doing about ghost networks?
Provider directory accuracy has received growing attention from lawmakers and regulators in recent years.
In 2024, the U.S. Senate Finance Committee advanced the bipartisan Requiring Enhanced & Accurate Lists of (REAL) Health Providers Act, which aims to improve provider directory accuracy and strengthen accountability for Medicare Advantage plans.
Several states have also introduced laws requiring insurers to update provider directories more frequently and improve network accuracy.
The Centers for Medicare & Medicaid Services (CMS) also requires Medicare Advantage organizations to maintain accurate provider directories and meet network adequacy standards.
How can healthcare organizations reduce ghost networks?
Improving provider directory accuracy requires ongoing collaboration between insurers and healthcare organizations.
Best practices include:
- Regular provider data verification
- Frequent directory updates
- Provider self-service tools
- Automated data validation
- Clear processes for reporting inaccuracies
- Regular communication with participating providers
Accurate provider information benefits patients, providers, and health plans alike by reducing unnecessary friction during the scheduling process.
How can providers help keep their information accurate?
Although insurers maintain provider directories, medical practices also play an important role.
Practices should regularly review and update:
- Accepted insurance plans
- Office addresses
- Phone numbers
- Provider availability
- New patient acceptance
- Office hours
- Specialty information
Keeping this information current helps patients find appropriate care while reducing unnecessary scheduling issues.
