Healthcare Fraud: How big is the problem? “…potential losses to healthcare fraud and corruption between €30-100 billion across Europe” “…estimates conservatively that $68 billion (3%) is fraud” “…approximately €180 billion euros or6 percent of global health care spending is lost to fraud each year”
Healthcare Fraud: wait…There’s more?? Estimates of 20% – 30% total FWAC in health care

Fraud, waste, & abuseWe need to focus on all of it Fraud Waste Abuse
Combating fwa: how do we deal with it? • Sometimes prosecutions are in order: • Criminal organizations • Doctors committing true fraud • Grievously offending doctors • In other words – for Fraud • What if companies do not want to prosecute? • Bad PR • Bad for customer retention • Legal action not possible • What do they do about waste and abuse? • Want to develop alternative strategies for identifying and dealing with doctors who are engaging in aberrant behavior (as opposed to fraud)

SAS Fraud Framework END-TO-END SOLUTION for Health Insurance
SAS fraud framework Unique Hybrid approach to analytics Predictive modelling (example): Number of previous investigations on the network may be input to the predictive model of a suspicious claim Text mining (example): Harnessing call center data Anomaly detection (example): Providers that have volumes or intensity far above their peers Database Searches (example): Looking for matches across the lists of sanctioned providers or death master files Database Searches Text Mining Predictive Modeling Anomaly Detection Analytic Decisioning Engine Business rule (example): A claim is suspicious if it is submitted for a person of the wrong gender Automated Business Rules Social Network Analysis SNA (example): Looking for a number of similar connected actors
Industry best practiceUsing hybrid analytics for fraud detection • Leverage unstructured data elements in analytics • Examples: • Claim/call center notes high-lighting key fraud risks (e.g., policy questions) • Static data elements (e.g., address) used for linking suspicious activity • Integration of rich case file information Enterprise Data Network Analysis Text Mining • Associative discovery thru automated link analysis • Examples: • Provider/claimant associated to known fraud • Linked members with like suspicious behaviors • Suspicious referrals to linked providers • Collusive network of providers & referrals Employer Data Medical Procedure For known patterns For unknown patterns For complex patterns For unstructured data For associativelinking • Rules to surface known fraud behaviors • Examples: • Inaccurate eligibility information • Unlicensed or Suspended Provider • Daily provider billing exceeds possible • CPT up-coding • Value of charges for procedure exceeds threshold • Algorithms to surface unusual (out-of-band) behaviors • Examples: • Abnormal service volume compared to similar providers • Ratio of $ / procedure exceed norm • # patients from outside surrounding area exceeds norm • Identify attributes of known fraud behavior • Examples: • Like patterns of claims as confirmed known fraud • Provider behavior similar to known fraud cases • Like provider/ network growth rate (velocity) Rules Anomaly Detection Predictive Models Claims Payments Provider / Member Referral Known Bad Lists 3rd Party Data Proactively applies combination of all approaches at entity and network levels Hybrid Approach

SAS Fraud framework Efficacy and the hybrid approach Additional variables further this benefit even more █Advanced analytics via Hybrid Analytics enhance fraud detection, improving the accuracy as well as finding cases near impossible in a manual process █Advanced analytics without Hybrid FRAUD If you examine 50% of the population, you would expect to find 50% of the fraud █ RANDOM POPULATION If the accuracy of detection doubles by using a hybrid approach, an investigation team would be able to find twice the amount of fraud with the same number of referrals!
