• , 8/16/2014: “Fraud and systematic overcharging are estimated at roughly $60 billion, or 10 percent, of Medicare’s costs every year, but the administration recovered only about $4.3 billion last year. The Centers for Medicare and Medicaid Services, which is responsible for overseeing the effort, manually reviews just three million of the estimated 1.2 billion claims it receives each year. “

• Medicaid waste fraud and abuse estimated 60-80 Billon

• US Healthcare National expenditure was 2.8 Trillion or $8,915 per person in 2012 – US HHS

What’s the Business Problem?

Global Healthcare Costs

Why is it Difficult?

• New Fraud Patterns created all the time

• Identify groups and networks of risky providers and members in the medical claims arena.

• Help investigators to do risk based investigations and focus on the most likely providers and members of fraud, waste and abuse.

• System automatically and continually learns patterns of risk based on known data fraud cases as well as continually learn on new cases as they are identified.

• This enables continuous feedback and improvement of the system and automated detection of risk cases based on these patterns.

Details Analysis of Risk Cases

Risk Analytics and Business

• Risk analytics is not an intuitive process

• It is the exercise of applying rules, algorithms and domain knowledge to data

• The data model is imbedded in the business processes and in the data that it produces

• Subject area expertise is essential to understanding the data and success of the project

• The blend of subject area knowledge and analytic expertise is a powerful combination

• DataMet can effectively identify groups and networks of risky providers

• DataMet helps investigators to focus on the most likely providers and members of fraud, waste and abuse.

• DataMet automatically learns patterns of risk based on known data fraud cases as well as well as new cases .

• DataMet enables continuous feedback and improvement of the system and automated detection of risk cases based on these patterns.

• DataMet is aimed at reducing the global waste and abuse which is estimated to be $600 billion/year US and globally
