The three parts of FWA
| Type | What it means | Examples |
|---|---|---|
| Fraud | Intentional deception to obtain payment | Billing for services not provided, recycled or altered documents, a different person treated under a member's policy |
| Waste | Overuse or unnecessary cost, without intent to deceive | Unnecessary tests, longer stays than needed, duplicate investigations |
| Abuse | Practices that lead to improper payment, without clear proof of intent | Upcoding to a higher-priced procedure, billing above the agreed tariff, unbundling package charges |
Why FWA matters
FWA raises the cost of cover for every member and employer. It also slows down honest claims, because claims teams spend time checking suspicious ones. Insurers, TPAs and regulators in most markets run FWA programmes to find and reduce it.
How FWA is detected
- Rules on claim fields: amount limits, frequency limits and invalid code combinations.
- Analytics and peer comparison: providers or members whose patterns differ sharply from similar ones.
- Document-level checks: reading the medical records, bills and photos behind the claim to find reused documents, identity substitution and billing above agreed rates.
- Investigation: a special investigation unit (SIU) reviews the flagged cases and decides.
A flag is a reason to review, not proof of fraud.
Where YIRA MedSense fits
YIRA MedSense adds the document-level checks: it reads medical documents into structured data, compares each new document with prior records, checks the ID photo against the hospital photo and structures hospital tariffs for bill checks. Across insurance operations it has flagged more than 5,000 cases for review. See health insurance fraud detection →
