Healthcare fraud costs Americans roughly $105 billion every year, a figure that includes $36.3 billion in health insurance fraud and $68.7 billion in Medicare and Medicaid fraud alone. That works out to about $932 per person, or nearly $3,800 for a family of four, added directly to insurance premiums. Preventing it requires action at every level: organizations need strong compliance programs and technology, and patients need to watch their own records closely.
The Most Common Fraud Schemes
Most healthcare fraud falls into a handful of well-documented patterns. Understanding them is the first step toward building defenses against them.
- Upcoding: Billing for a more expensive service than the patient actually received. A routine office visit gets submitted as a complex evaluation, for example.
- Phantom billing: Charging for a service, visit, or supply the patient never received at all.
- Unbundling: Breaking a single service into multiple separate charges to inflate the total bill.
- Double billing: Submitting multiple claims for the same service.
These schemes can be committed by individual providers, organized fraud rings, or even patients who lend their insurance information to others. They persist because the healthcare billing system is enormous and complex, making it difficult to catch irregular claims buried among millions of legitimate ones.
Building a Compliance Program
The Office of Inspector General (OIG) at the U.S. Department of Health and Human Services lays out seven core elements that every healthcare organization’s compliance program should include. These aren’t optional best practices for organizations that bill federal programs; they’re the baseline expectation regulators use when evaluating whether an organization is serious about preventing fraud.
The seven elements are: written policies and procedures, a designated compliance officer and committee, effective training and education, open lines of communication for reporting concerns, internal monitoring and auditing, enforcement through well-publicized disciplinary guidelines, and prompt corrective action when problems are detected.
The most important thing to understand about these elements is that they work as a system. Written policies mean nothing without training. Training means nothing without a way for employees to report violations safely. And reporting channels are useless if leadership doesn’t respond with real corrective action. Organizations that treat compliance as a checklist rather than a culture tend to discover fraud only after regulators come knocking.
Using Technology to Detect Suspicious Claims
Machine learning has become the dominant tool for catching fraudulent claims before they’re paid. A 2024 systematic review found over 140 studies on the topic, with the vast majority focused on detecting fraud committed by healthcare providers. Researchers have used both supervised approaches (where algorithms learn from known fraud cases) and unsupervised methods (where algorithms flag statistical outliers without needing labeled examples).
In practice, these systems analyze billing patterns in real time and flag anomalies: a provider who bills far more complex procedures than peers in the same specialty, a sudden spike in claims from a single clinic, or patterns of unbundling that would be invisible in manual reviews. Insurers and government programs increasingly rely on these tools as a first line of defense.
The technology has real limitations, though. Healthcare claims data is inconsistent across systems, privacy regulations restrict how data can be shared, and confirmed fraud cases are relatively rare compared to legitimate claims, which makes it harder to train algorithms effectively. Deep learning techniques are gaining traction and may improve detection accuracy, but the field still struggles with standardization and transparency in how data is prepared and models are built.
Verifying Patient Identity
A surprising amount of fraud hinges on identity: someone uses another person’s insurance card, a provider bills under a patient who never visited, or duplicate medical records allow claims to slip through. Biometric identification systems, particularly fingerprint-based verification, offer a powerful countermeasure.
Fingerprint identification has a failure rate of approximately one in a billion when two fingerprints are available. Unlike plastic wristbands or insurance cards, fingerprints can’t be lost, damaged, or swapped between patients. Biometric systems also prevent the creation of duplicate records for the same person, closing a common loophole that fraudsters exploit. In situations where a patient can’t provide their own information, biometric data can still confirm their identity and pull up their records.
For organizations looking to reduce both fraud and medical errors, biometric verification at check-in is one of the most effective investments available.
Internal Auditing and Monitoring
Regular audits are where most fraud is actually caught at the organizational level. Effective auditing means reviewing a representative sample of claims, comparing billing patterns against benchmarks, and investigating outliers before they become systemic problems.
The audit process should look at coding accuracy (are services coded at the right level?), documentation completeness (does the medical record support the claim?), and billing consistency (are the same services being billed differently across providers?). When audits reveal problems, the response matters as much as the finding. Patterns of upcoding might indicate a training gap, but they could also indicate intentional fraud. The compliance team needs clear protocols for escalating findings and, when necessary, self-reporting to regulators.
Many organizations also use claim scrubbing software that automatically checks claims against coding rules before submission. This catches unintentional errors, which account for a significant portion of improper payments, and removes the low-hanging fruit so auditors can focus on genuinely suspicious patterns.
What Patients Can Do
Patients are often the first people who can spot fraud, because they know what services they actually received. The HHS Office of Inspector General recommends three core habits: protect your personal information, check your medical bills and statements carefully, and report anything that looks wrong.
Your Explanation of Benefits (EOB) statement from your insurer is your most useful tool. Every time you receive one, compare it against what actually happened at your appointment. Look for services you didn’t receive, dates you weren’t seen, or charges from providers you’ve never visited. If something doesn’t match, contact your insurer first to clarify, then report it if the discrepancy can’t be explained.
Medical identity theft is a growing concern. If someone gains access to your insurance information, they can rack up claims in your name, which not only costs money but can contaminate your medical record with someone else’s diagnoses, allergies, and medications. Guard your insurance card the way you guard your credit cards. Don’t share your member ID with anyone, and be cautious about providing insurance information over the phone unless you initiated the call.
How to Report Suspected Fraud
If you suspect healthcare fraud, the HHS Office of Inspector General operates a hotline that accepts tips from anyone. You can file a complaint online through the OIG website or call 1-800-HHS-TIPS. The hotline covers fraud, waste, and abuse in Medicare, Medicaid, and other HHS programs.
Employees and contractors who report fraud from inside an organization have whistleblower protections. The OIG provides specific guidance on these protections, and the False Claims Act allows whistleblowers to file lawsuits on behalf of the government and receive a percentage of any recovered funds. This financial incentive has made whistleblower suits one of the most effective enforcement mechanisms in healthcare fraud, generating billions in recoveries each year.
For fraud involving private insurance rather than government programs, contact your state’s Department of Insurance or the insurer’s fraud investigation unit directly. Most insurers have dedicated fraud hotlines listed on the back of your insurance card or on their website.
