Fraud, Waste, and Abuse (FWA) Explained: Real-World Scenarios and Examples

Understanding Fraud in Healthcare

Fraud, Waste, and Abuse (FWA) are often grouped together, but fraud is distinct: it is an intentional deception or misrepresentation made to obtain an unauthorized benefit. In healthcare, fraud undermines trust, diverts resources, and can harm patients through unnecessary or unsafe care.

Common fraudulent schemes include upcoding, unbundling, phantom or duplicate billing, billing for services not rendered, falsifying documentation, and offering or accepting kickbacks. The False Claims Act targets knowingly false or reckless claims to government programs, while the Anti-Kickback Statute—often called the Kickback Statute—prohibits remuneration for referrals that can distort medical judgment.

Real-world fraud scenarios

• Upcoding: A clinic bills a high-complexity evaluation and management visit for a brief check-in that lacked the required history, exam, or decision-making.
• Unbundling: A laboratory bills each component of a test panel separately to increase payment when a bundled code should be used.
• Kickbacks: A supplier pays “consulting fees” to physicians in exchange for device referrals, violating the Kickback Statute.
• Phantom billing: Durable medical equipment is billed but never delivered, with forged delivery receipts in the file.
• Telehealth misrepresentation: Telephone calls are billed as longer, in-person visits without documentation to support the level of service.

Indicators that suggest fraud risk

• Outlier coding (e.g., unusually high rates of level-5 visits or add-on codes).
• Identical notes across patients, excessive copy-paste, or missing signatures.
• Claims billed when the provider was not present or licensed to perform the service.
• Frequent use of modifiers that bypass edits without clear justification.

Identifying Wasteful Practices

Waste reflects the careless or inefficient use of resources that increases costs without improving outcomes. It often arises from poor processes, weak coordination, or lack of adherence to evidence-based guidelines rather than intent to deceive.

Typical waste examples

• Duplicative imaging or lab tests because prior results were not retrieved or shared.
• Ordering low-value screening in patients unlikely to benefit, or daily labs on stable inpatients by default.
• Choosing higher-cost branded drugs when clinically equivalent generics are available.
• Inefficient revenue cycle steps that trigger avoidable claim denials and rework.

How you can spot waste

• Monitor outlier utilization and length of stay compared with peers and case-mix.
• Audit order sets and standing protocols for unnecessary defaults.
• Track generic dispensing rates and therapeutic interchange opportunities.
• Review denial reasons; fix upstream documentation and coding gaps that cause rework.

Recognizing Abuse in Medical Billing

Abuse involves practices that are inconsistent with sound medical, business, or fiscal practices and that lead to unnecessary costs or improper payment. Unlike fraud, intent may be unclear, but the behavior still violates program or payer rules.

Abuse examples you may encounter

• Systematically billing higher visit levels than documentation supports (“level creep”).
• Using modifiers to bypass edits when services are not truly distinct.
• Charging excessive fees compared with customary charges in the service area.
• Billing for services that lack medical necessity documentation or proper supervision.

Abuse can trigger education, repayment, and corrective action plans—and, if it becomes knowing or reckless, escalate into liability under the False Claims Act.

Impact of FWA on Healthcare Systems

FWA inflates premiums and taxes, reduces funds for essential services, and crowds out high-value care. You may see longer wait times, restricted formularies, and fewer resources for prevention because dollars are diverted to low- or no-value activity.

Clinically, FWA can expose patients to unnecessary tests, procedures, and adverse events. Operationally, it burdens staff with audits, investigations, and rework, while eroding public trust in providers and payers. The ripple effects reach community health, as strained budgets limit investments in primary care, behavioral health, and social drivers of health.

Strategies to Prevent Fraud Waste and Abuse

Build a strong compliance foundation

• Adopt a written program based on OIG Compliance Program Guidance with clear policies, a code of conduct, and leadership oversight.
• Provide role-based training on documentation, coding, and referral rules, including the Kickback Statute and the False Claims Act.
• Maintain an anonymous reporting hotline and robust non-retaliation policy to encourage early issue spotting.

Strengthen pre- and post-payment controls

• Use National Correct Coding Initiative logic and payer edits to prevent upcoding and unbundling at submission.
• Deploy analytics for anomaly detection, peer benchmarking, and network analysis to flag outliers before payment.
• Conduct targeted probe-and-educate reviews and focused audits of high-risk codes, modifiers, and providers.
• Verify medical necessity using evidence-based criteria; require documentation of time, complexity, and supervision.

Tighten vendor and provider oversight

• Screen and credential providers; check exclusion lists and licensure status regularly.
• Manage third parties with contracts that require cooperation in audits and adherence to Compliance Program Guidance.
• Monitor durable medical equipment and telehealth arrangements, where FWA risk is elevated.

Engage patients and staff

• Educate patients to review explanations of benefits and report services they did not receive.
• Empower clinical teams to refine order sets, remove low-value defaults, and adopt generic-first prescribing.

Leverage public initiatives

• Coordinate with Health Care Fraud Enforcement partners and state Medicaid Fraud Control Units.
• Align internal reviews with the Medicaid Integrity Program focus areas if you serve Medicaid populations.

Legal and Regulatory Frameworks

The False Claims Act imposes liability for knowingly submitting false claims to federal health programs and permits whistleblowers to file qui tam actions. Treble damages and penalties create strong incentives to prevent and promptly repay improper claims.

The Anti-Kickback Statute (Kickback Statute) prohibits offering, soliciting, paying, or receiving anything of value to induce referrals for items or services payable by federal programs. Violations can trigger criminal charges, civil monetary penalties, and exclusion from participation.

The Medicaid Integrity Program supports audits, provider education, and data analysis to protect Medicaid funds. Health Care Fraud Enforcement initiatives unite the Department of Justice, HHS-OIG, and other partners in coordinated investigations and prosecutions.

OIG’s Compliance Program Guidance outlines seven core elements—standards, oversight, training, communication, monitoring, enforcement, and response—that you can tailor to your organization. Self-disclosure protocols and timely refunds of identified overpayments help mitigate risk.

Case Studies of FWA

Case 1: Upcoding evaluation and management visits

A primary care group billed high-complexity visits for routine medication refills. Documentation showed limited history and decision-making. Peer benchmarking flagged outlier rates of level-5 codes. Education, claim reprocessing, and an internal audit led to repayments and revised templates.

Case 2: Unbundled lab panels

A lab split comprehensive metabolic panels into individual tests to increase reimbursement. Claims edits and the National Correct Coding Initiative logic identified the pattern. The lab rebilled using the appropriate bundled code and implemented automated checks to prevent recurrence.

Case 3: Kickbacks in device referrals

A device supplier paid “marketing honoraria” tied to referral volumes. Emails and contracts lacked legitimate services. Compliance escalated and outside counsel reviewed. The arrangement was unwound, funds were repaid, and the parties adopted strict anti-kickback controls and fair market value reviews.

Case 4: Phantom durable medical equipment

Beneficiaries reported receiving invoices for wheelchairs never delivered. Delivery logs were forged. A hotline tip spurred a site visit; inventory records did not match claims. The supplier was terminated, claims were voided, and patient outreach verified actual needs.

Case 5: Telehealth billed as in-person

Audio-only follow-ups were billed as extended in-person visits. Call logs showed brief durations. Policy updates clarified telehealth billing rules, and the practice instituted real-time prompts for place-of-service and time documentation.

Case 6: Medicaid transportation mileage inflation

A transportation vendor regularly billed maximum mileage regardless of actual distance. GPS audits and member confirmations exposed the discrepancy. The plan recouped overpayments and implemented geofenced trip verification.

Case 7: Home health visit inflation

Notes showed identical, copied assessments and visit times that exceeded staffing capacity. Data analytics and unannounced supervisory visits confirmed overreporting. The agency entered into a corrective action plan with ongoing monitoring and staff retraining.

Conclusion

Addressing Fraud, Waste, and Abuse (FWA) protects patients, strengthens trust, and frees resources for high-value care. By combining strong Compliance Program Guidance, vigilant analytics, and a culture that encourages speaking up, you can prevent errors, detect misconduct early, and respond decisively under the False Claims Act, Kickback Statute, and Medicaid Integrity Program expectations.
