CAE Research Drivers • Legislation • Work Orders • Scenarios
CAE Research Drivers Legislation, specifically • ARPA of 2000 “…The Secretary shall establish procedures under which the Corporation will be able to identify the following: …
CAE Research Drivers • Any person performing loss adjustment services relative to coverage offered under this title where such loss adjustments performed by the person result in accepted or denied claims equal to or greater than 150 percent … of the mean for accepted or denied claims (as applicable) for all other persons performing loss adjustment services in the same area, as determined by the Corporation….” • In addition to crop adjusters, ARPA included crop insurance agents.
CAE Research Drivers • Work Orders - RMA Personnel Routinely Submit Requests (That Result in Work Orders) Which Focus the Research Resources of CAE • Scenarios* • Over sixty scenarios/sub-scenarios • Initiated scenario development early in 2001 *Indicators of Fraud, Waste, and Abuse
Spot Check List: 2002 Data for ARPA Requirement Scenarios for Spot Check: • Triplets • Frequent Filers • Yield Switching • Prevented Planting Frequent Filers • Producers Associated With All or Nothing Agents • Crop Units With Excessive Yields • Under Reported Harvested Production • Rare Big Losers
Rare Big Losers • Identify Rare Multi-year Losers, Using the Probability of Loss • Local Yield Variability Considered • Cluster and Factor Analysis Show the Importance of Local Conditions • A Producer’s Loss Ratios Strongly Related to Insurance Plan and Coverage Level Spot Check 2002
Iowa & Oklahoma Are Different! Spot Check 2002 Region, Insurance Plan, & Coverage Level
Rare Big Losers Average Indemnity of $98,664 Spot Check 2002
Rare Big Losers Results* • 350 Unique Producers Accounting for $34,532,565 of Indemnity in 2002 • They Were Flagged at the 0.0001 Level • Average Indemnity of $98,664 • 72.5 Percent of Their Policies Resulted in a Significant Loss *Indicators of Fraud, Waste, and Abuse Spot Check 2002
All or Nothing • Producers Who Are Associated With All or Nothing Agents • All or Nothing Agents are those Agents Who Have Disproportionate Numbers of Crop Policies With Total Losses Compared to Other Agents Within Same Area • Associated Producers Have Total Loss Claims • Associated Producers Who Were Indemnified in More Than One Year Spot Check 2002
All or Nothing Producers $12,150,707 Indemnity for 236 Producers Spot Check 2002
2002 Spot Check List Summary Scenario*IndemnityProducers Triplets $ 4,332,310 99 Frequent Fliers $21,718,632 328 Yield Switching $15,486,631 285 Prevented Planting FF $7,011,644 60 All or Nothing $12,150,707 236 Excessive Yield $36,201,574 389 Under Reported Harvest Prod $23,502,812 225 Rare Big Losers $32,817,867 323 Unduplicated Totals $137,678,258 1,808 *Indicators of Fraud, Waste, and Abuse
Total 2002 Spot Check List$137,678,258 Indemnity for 1808 Insureds
Data Mining ActivitiesPublicized in Weekly Newsletter Newsletter Volume 1, No. 1Week of February 7, 2003 This week, the development of the 2003 Spot Check List is a continuing major research activity and includes all CAE staff members. The following scenarios are the basis for the Spot Check List (SCL) that will be finalized for delivery to RMA early in March.
Cost-Benefit Analysis Data Mining Pays Off
Cost-Benefit Analysis Examples • Data Mining In Texas Similar to CAE’s, Identified Areas of Tax Underpayment • In FY 2000, The State of Texas Comptroller Collected An Additional $43 Million in Taxes From Areas of Underpayment Identified Through Data Mining
Cost-Benefit Analysis • Texas Blue Cross-Blue Shield Developed a Medical Insurance Data Warehouse • In the First Three Months, Data Mining Identified Enough Medical Fraud to Pay for the Data Warehouse & Mining
Conclusions • Data Mining Can Detect Patterns of Waste, Fraud, and Abuse • Millions of Taxpayer and Insurance Provider Dollars Can Be Saved Through Data Mining Using Forensic Analysis Techniques • This Research Provides USDA with Analysis Tools Previously Unavailable
Conclusions • Crop Insurance Is Vulnerable to Multiple Methods of Fraud, Waste and Abuse • A Small Number of Agents, Adjusters and Producers Are Linked to Anomalous Behavior
