Data Scientist Jan. 2018 – January 2020

Projects:

1. Medical Claim Denial Management Using Machine Learning Techniques o Goal:

The project was to predict and prevent errors in medical claims payment processing. Specifically,

• The ability to predict prior to submission if a specific claim will be processed correctly and receive full payment, or processed incorrectly and declined or not paid in full.

• Detect regularities in incorrectly processed claims. o Approach - Supervised Machine Learning for Classification & Anomaly Detection o Algorithms - Two Class Support Vector Machine, Random Forest, Logistic Regression, Decision Tree, PCA-Based Anomaly Detection o Scripting language -Python ( Pandas and Scikit-learn Libraries) o Environment - Azure Machine Learning Studio

2. Predictive Analytics in Health Insurance Claims

The goal of this project is to use predictive analytics to reduce claim duration and costs.

By using predictive analytics to sift through millions of data sets, claims specialists can uncover complex patterns, trends and correlations that otherwise would pass undetected.

Machine learning algorithms are employed to make sense of these associations and putting this knowledge in the right hands quickly..

The model and deployment from this project will provide insights about the likelihood of future claim events, ferrets out instances of fraudulent claims activity, and ensures appropriate treatments. It also can be applied to discover the possibility of fraud, waste and abuse.
