Fraud, Waste, and Abuse Detection and Prevention
What this domain tests
You must distinguish the three concepts and know the detection signals. Fraud = intentional deception for gain; waste = misuse of resources without intent; abuse = practices inconsistent with sound business/clinical practice that cause unnecessary cost. Concepts: common schemes (upcoding, unbundling, phantom billing, duplicate billing, services not rendered, medically unnecessary services, kickbacks); red flags (billing patterns, outliers, same-day duplicates, impossible volumes, high modifier use, beneficiary complaints); data analytics and predictive modeling; the seven elements of a compliance program; exclusion screening (OIG LEIE, SAM); whistleblower/qui tam protections; and the 60-day overpayment rule.
Traps that show up in questions
- Labeling every error 'fraud' - intent matters; many errors are waste or abuse.
- Forgetting that an overpayment must be identified, quantified, and reported/returned within the regulatory timeframe (generally 60 days from identification).
- Missing that exclusion screening is a compliance program requirement, not an optional best practice.
- Assuming a provider with high utilization is committing fraud - outliers require investigation, not accusation.
- Overlooking that intent is the dividing line between fraud and abuse/waste.
Rule of thumb
Ask: Was it intentional? If yes → fraud. If no but it was unnecessary or inconsistent with sound practice → abuse. If it was inefficient use of resources without intent → waste. Then verify the compliance response (report, return, correct).
Worked example
A coder bills the same procedure twice on the same date for the same patient with no supporting documentation. If the duplicate was a system error → waste/abuse with a corrective action. If the coder knowingly billed it to increase revenue → fraud. The reviewer's job is to document the facts and route it; the intent determination is made by compliance/legal.
