Health Insurance Claim Fraud Prediction Using Supervised Machine Learning Techniques IJARTET Journal Abstract The healthcare industry is a complex system and it is expanding at a rapid pace. To demonstrate this, NARX model (nonlinear autoregressive network having exogenous inputs), is a recurrent dynamic network was tested and compared against feed forward artificial neural network. Predicting medical insurance costs using ML approaches is still a problem in the healthcare industry that requires investigation and improvement. Accuracy defines the degree of correctness of the predicted value of the insurance amount. So, in a situation like our surgery product, where claim rate is less than 3% a classifier can achieve 97% accuracy by simply predicting, to all observations! Adapt to new evolving tech stack solutions to ensure informed business decisions. We see that the accuracy of predicted amount was seen best. If you have some experience in Machine Learning and Data Science you might be asking yourself, so we need to predict for each policy how many claims it will make. Copyright 1988-2023, IGI Global - All Rights Reserved, Goundar, Sam, et al. Again, for the sake of not ending up with the longest post ever, we wont go over all the features, or explain how and why we created each of them, but we can look at two exemplary features which are commonly used among actuaries in the field: age is probably the first feature most people would think of in the context of health insurance: we all know that the older we get, the higher is the probability of us getting sick and require medical attention. Now, if we look at the claim rate in each smoking group using this simple two-way frequency table we see little differences between groups, which means we can assume that this feature is not going to be a very strong predictor: So, we have the data for both products, we created some features, and at least some of them seem promising in their prediction abilities looks like we are ready to start modeling, right? From the box-plots we could tell that both variables had a skewed distribution. needed. Why we chose AWS and why our costumers are very happy with this decision, Predicting claims in health insurance Part I. Achieve Unified Customer Experience with efficient and intelligent insight-driven solutions. Notebook. Users can develop insurance claims prediction models with the help of intuitive model visualization tools. Those setting fit a Poisson regression problem. Neural networks can be distinguished into distinct types based on the architecture. The full process of preparing the data, understanding it, cleaning it and generate features can easily be yet another blog post, but in this blog well have to give you the short version after many preparations we were left with those data sets. Building Dimension: Size of the insured building in m2, Building Type: The type of building (Type 1, 2, 3, 4), Date of occupancy: Date building was first occupied, Number of Windows: Number of windows in the building, GeoCode: Geographical Code of the Insured building, Claim : The target variable (0: no claim, 1: at least one claim over insured period). Machine Learning approach is also used for predicting high-cost expenditures in health care. Apart from this people can be fooled easily about the amount of the insurance and may unnecessarily buy some expensive health insurance. Health Insurance Claim Prediction Using Artificial Neural Networks. Claims received in a year are usually large which needs to be accurately considered when preparing annual financial budgets. ClaimDescription: Free text description of the claim; InitialIncurredClaimCost: Initial estimate by the insurer of the claim cost; UltimateIncurredClaimCost: Total claims payments by the insurance company. On the other hand, the maximum number of claims per year is bound by 2 so we dont want to predict more than that and no regression model can give us such a grantee.

Dr. Akhilesh Das Gupta Institute of Technology & Management. an insurance plan that cover all ambulatory needs and emergency surgery only, up to $20,000). It helps in spotting patterns, detecting anomalies or outliers and discovering patterns. According to Zhang et al. Factors determining the amount of insurance vary from company to company. The distribution of number of claims is: Both data sets have over 25 potential features. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. According to our dataset, age and smoking status has the maximum impact on the amount prediction with smoker being the one attribute with maximum effect. Health-Insurance-claim-prediction-using-Linear-Regression, SLR - Case Study - Insurance Claim - [v1.6 - 13052020].ipynb. As a result, the median was chosen to replace the missing values. Results indicate that an artificial NN underwriting model outperformed a linear model and a logistic model. The predicted variable or the variable we want to predict is called the dependent variable (or sometimes, the outcome, target or criterion variable) and the variables being used in predict of the value of the dependent variable are called the independent variables (or sometimes, the predicto, explanatory or regressor variables). This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Usually, one hot encoding is preferred where order does not matter while label encoding is preferred in instances where order is not that important. This may sound like a semantic difference, but its not. Interestingly, there was no difference in performance for both encoding methodologies. Refresh the page, check. The goal of this project is to allows a person to get an idea about the necessary amount required according to their own health status. You signed in with another tab or window. It was gathered that multiple linear regression and gradient boosting algorithms performed better than the linear regression and decision tree. Gradient boosting is best suited in this case because it takes much less computational time to achieve the same performance metric, though its performance is comparable to multiple regression. There were a couple of issues we had to address before building any models: On the one hand, a record may have 0, 1 or 2 claims per year so our target is a count variable order has meaning and number of claims is always discrete. In the insurance business, two things are considered when analysing losses: frequency of loss and severity of loss. The authors Motlagh et al. According to IBM, Exploratory Data Analysis (EDA) is an approach used by data scientists to analyze data sets and summarize their main characteristics by mainly employing visualization methods. The model predicted the accuracy of model by using different algorithms, different features and different train test split size. Health insurance is a necessity nowadays, and almost every individual is linked with a government or private health insurance company. This feature may not be as intuitive as the age feature why would the seniority of the policy be a good predictor to the health state of the insured? Training data has one or more inputs and a desired output, called as a supervisory signal. Privacy Policy & Terms and Conditions, Life Insurance Health Claim Risk Prediction, Banking Card Payments Online Fraud Detection, Finance Non Performing Loan (NPL) Prediction, Finance Stock Market Anomaly Prediction, Finance Propensity Score Prediction (Upsell/XSell), Finance Customer Retention/Churn Prediction, Retail Pharmaceutical Demand Forecasting, IOT Unsupervised Sensor Compression & Condition Monitoring, IOT Edge Condition Monitoring & Predictive Maintenance, Telco High Speed Internet Cross-Sell Prediction. This amount needs to be included in the yearly financial budgets. Also with the characteristics we have to identify if the person will make a health insurance claim. Description. Usually a random part of data is selected from the complete dataset known as training data, or in other words a set of training examples. The ability to predict a correct claim amount has a significant impact on insurer's management decisions and financial statements. Goundar, S., Prakash, S., Sadal, P., & Bhardwaj, A. Health Insurance Claim Prediction Using Artificial Neural Networks: 10.4018/IJSDA.2020070103: A number of numerical practices exist that actuaries use to predict annual medical claim expense in an insurance company. Health Insurance Claim Prediction Using Artificial Neural Networks. A major cause of increased costs are payment errors made by the insurance companies while processing claims. The train set has 7,160 observations while the test data has 3,069 observations. This Notebook has been released under the Apache 2.0 open source license. As a result, we have given a demo of dashboards for reference; you will be confident in incurred loss and claim status as a predicted model. According to Rizal et al. Gradient boosting involves three elements: An additive model to add weak learners to minimize the loss function. The website provides with a variety of data and the data used for the project is an insurance amount data. Health Insurance Cost Predicition. In this learning, algorithms take a set of data that contains only inputs, and find structure in the data, like grouping or clustering of data points. Last modified January 29, 2019, Your email address will not be published. How to get started with Application Modernization? Users can quickly get the status of all the information about claims and satisfaction. Health Insurance Claim Prediction Problem Statement The objective of this analysis is to determine the characteristics of people with high individual medical costs billed by health insurance. Random Forest Model gave an R^2 score value of 0.83. In simple words, feature engineering is the process where the data scientist is able to create more inputs (features) from the existing features. (2016), neural network is very similar to biological neural networks. Pre-processing and cleaning of data are one of the most important tasks that must be one before dataset can be used for machine learning. Children attribute had almost no effect on the prediction, therefore this attribute was removed from the input to the regression model to support better computation in less time. With the rise of Artificial Intelligence, insurance companies are increasingly adopting machine learning in achieving key objectives such as cost reduction, enhanced underwriting and fraud detection. Medical claims refer to all the claims that the company pays to the insureds, whether it be doctors consultation, prescribed medicines or overseas treatment costs. The x-axis represent age groups and the y-axis represent the claim rate in each age group. In addition, only 0.5% of records in ambulatory and 0.1% records in surgery had 2 claims. In the interest of this project and to gain more knowledge both encoding methodologies were used and the model evaluated for performance. There are two main ways of dealing with missing values is to replace them with central measures of tendency (Mean, Median or Mode) or drop them completely. The network was trained using immediate past 12 years of medical yearly claims data. Though unsupervised learning, encompasses other domains involving summarizing and explaining data features also. This can help not only people but also insurance companies to work in tandem for better and more health centric insurance amount. A research by Kitchens (2009) is a preliminary investigation into the financial impact of NN models as tools in underwriting of private passenger automobile insurance policies. A decision tree with decision nodes and leaf nodes is obtained as a final result. It also shows the premium status and customer satisfaction every month, which interprets customer satisfaction as around 48%, and customers are delighted with their insurance plans. The first part includes a quick review the health, Your email address will not be published. An inpatient claim may cost up to 20 times more than an outpatient claim. The main aim of this project is to predict the insurance claim by each user that was billed by a health insurance company in Python using scikit-learn. Decision on the numerical target is represented by leaf node. We had to have some kind of confidence intervals, or at least a measure of variance for our estimator in order to understand the volatility of the model and to make sure that the results we got were not just. It is based on a knowledge based challenge posted on the Zindi platform based on the Olusola Insurance Company. Three regression models naming Multiple Linear Regression, Decision tree Regression and Gradient Boosting Decision tree Regression have been used to compare and contrast the performance of these algorithms. It has been found that Gradient Boosting Regression model which is built upon decision tree is the best performing model. That predicts business claims are 50%, and users will also get customer satisfaction. ), Goundar, Sam, et al. The value of (health insurance) claims data in medical research has often been questioned (Jolins et al. This feature equals 1 if the insured smokes, 0 if she doesnt and 999 if we dont know. Insurance companies are extremely interested in the prediction of the future. However, it is. It is very complex method and some rural people either buy some private health insurance or do not invest money in health insurance at all. The authors Motlagh et al. This can help not only people but also insurance companies to work in tandem for better and more health centric insurance amount. 1. Prediction is premature and does not comply with any particular company so it must not be only criteria in selection of a health insurance. (2020) proposed artificial neural network is commonly utilized by organizations for forecasting bankruptcy, customer churning, stock price forecasting and in many other applications and areas. Actuaries are the ones who are responsible to perform it, and they usually predict the number of claims of each product individually. The real-world data is noisy, incomplete and inconsistent. The dataset is comprised of 1338 records with 6 attributes. This amount needs to be included in Coders Packet . (2016) emphasize that the idea behind forecasting is previous know and observed information together with model outputs will be very useful in predicting future values. (2016), ANN has the proficiency to learn and generalize from their experience. arrow_right_alt. Dataset is not suited for the regression to take place directly. These claim amounts are usually high in millions of dollars every year. Artificial neural networks (ANN) have proven to be very useful in helping many organizations with business decision making. ANN has the ability to resemble the basic processes of humans behaviour which can also solve nonlinear matters, with this feature Artificial Neural Network is widely used with complicated system for computations and classifications, and has cultivated on non-linearity mapped effect if compared with traditional calculating methods. The data included various attributes such as age, gender, body mass index, smoker and the charges attribute which will work as the label. Where a person can ensure that the amount he/she is going to opt is justified. 11.5s. Whereas some attributes even decline the accuracy, so it becomes necessary to remove these attributes from the features of the code. Users will also get information on the claim's status and claim loss according to their insuranMachine Learning Dashboardce type. The data was in structured format and was stores in a csv file format. Insurance Companies apply numerous models for analyzing and predicting health insurance cost. The basic idea behind this is to compute a sequence of simple trees, where each successive tree is built for the prediction residuals of the preceding tree. Regression analysis allows us to quantify the relationship between outcome and associated variables. In fact, the term model selection often refers to both of these processes, as, in many cases, various models were tried first and best performing model (with the best performing parameter settings for each model) was selected. (2011) and El-said et al. Predicting the Insurance premium /Charges is a major business metric for most of the Insurance based companies. ANN has the ability to resemble the basic processes of humans behaviour which can also solve nonlinear matters, with this feature Artificial Neural Network is widely used with complicated system for computations and classifications, and has cultivated on non-linearity mapped effect if compared with traditional calculating methods. The main application of unsupervised learning is density estimation in statistics. Appl. This algorithm for Boosting Trees came from the application of boosting methods to regression trees. Dataset was used for training the models and that training helped to come up with some predictions. Where a person can ensure that the amount he/she is going to opt is justified. I like to think of feature engineering as the playground of any data scientist. Two main types of neural networks are namely feed forward neural network and recurrent neural network (RNN). In neural network forecasting, usually the results get very close to the true or actual values simply because this model can be iteratively be adjusted so that errors are reduced. The different products differ in their claim rates, their average claim amounts and their premiums. (2020) proposed artificial neural network is commonly utilized by organizations for forecasting bankruptcy, customer churning, stock price forecasting and in many other applications and areas. According to Rizal et al. This research focusses on the implementation of multi-layer feed forward neural network with back propagation algorithm based on gradient descent method. Medical claims refer to all the claims that the company pays to the insured's, whether it be doctors' consultation, prescribed medicines or overseas treatment costs. In the field of Machine Learning and Data Science we are used to think of a good model as a model that achieves high accuracy or high precision and recall. by admin | Jul 6, 2022 | blog | 0 comments, In this 2-part blog post well try to give you a taste of one of our recently completed POC demonstrating the advantages of using Machine Learning (read here) to predict the future number of claims in two different health insurance product. Example, Sangwan et al. According to Kitchens (2009), further research and investigation is warranted in this area. (R rural area, U urban area). Here, our Machine Learning dashboard shows the claims types status. Are you sure you want to create this branch? Numerical data along with categorical data can be handled by decision tress. The primary source of data for this project was from Kaggle user Dmarco. 99.5% in gradient boosting decision tree regression. Data. Previous research investigated the use of artificial neural networks (NNs) to develop models as aids to the insurance underwriter when determining acceptability and price on insurance policies. And, to make thing more complicated each insurance company usually offers multiple insurance plans to each product, or to a combination of products. Goundar, S., Prakash, S., Sadal, P., & Bhardwaj, A. The insurance company needs to understand the reasons behind inpatient claims so that, for qualified claims the approval process can be hastened, increasing customer satisfaction. Results indicate that an artificial NN underwriting model outperformed a linear model and a logistic model. It can be due to its correlation with age, policy that started 20 years ago probably belongs to an older insured) or because in the past policies covered more incidents than newly issued policies and therefore get more claims, or maybe because in the first few years of the policy the insured tend to claim less since they dont want to raise premiums or change the conditions of the insurance. Also it can provide an idea about gaining extra benefits from the health insurance. Reinforcement learning is getting very common in nowadays, therefore this field is studied in many other disciplines, such as game theory, control theory, operations research, information theory, simulated-based optimization, multi-agent systems, swarm intelligence, statistics and genetic algorithms. 2 shows various machine learning types along with their properties. Predicting the cost of claims in an insurance company is a real-life problem that needs to be solved in a more accurate and automated way. So cleaning of dataset becomes important for using the data under various regression algorithms. Claim rate, however, is lower standing on just 3.04%. Neural networks can be distinguished into distinct types based on the architecture. Abhigna et al. 1993, Dans 1993) because these databases are designed for nancial . (2013) and Majhi (2018) on recurrent neural networks (RNNs) have also demonstrated that it is an improved forecasting model for time series. Step 2- Data Preprocessing: In this phase, the data is prepared for the analysis purpose which contains relevant information. We are building the next-gen data science ecosystem https://www.analyticsvidhya.com. Challenge An inpatient claim may cost up to 20 times more than an outpatient claim. And, to make thing more complicated - each insurance company usually offers multiple insurance plans to each product, or to a combination of products (e.g. Each plan has its own predefined . ). In health insurance many factors such as pre-existing body condition, family medical history, Body Mass Index (BMI), marital status, location, past insurances etc affects the amount. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. (2017) state that artificial neural network (ANN) has been constructed on the human brain structure with very useful and effective pattern classification capabilities. The model was used to predict the insurance amount which would be spent on their health. This research focusses on the implementation of multi-layer feed forward neural network with back propagation algorithm based on gradient descent method. Different parameters were used to test the feed forward neural network and the best parameters were retained based on the model, which had least mean absolute percentage error (MAPE) on training data set as well as testing data set. Regression or classification models in decision tree regression builds in the form of a tree structure. In a dataset not every attribute has an impact on the prediction. Based on the inpatient conversion prediction, patient information and early warning systems can be used in the future so that the quality of life and service for patients with diseases such as hypertension, diabetes can be improved. Your email address will not be published. Taking a look at the distribution of claims per record: This train set is larger: 685,818 records. In I. Libraries used: pandas, numpy, matplotlib, seaborn, sklearn. The topmost decision node corresponds to the best predictor in the tree called root node. The dataset is divided or segmented into smaller and smaller subsets while at the same time an associated decision tree is incrementally developed. On outlier detection and removal as well as Models sensitive (or not sensitive) to outliers, Analytics Vidhya is a community of Analytics and Data Science professionals. Once training data is in a suitable form to feed to the model, the training and testing phase of the model can proceed. We explored several options and found that the best one, for our purposes, section 3) was actually a single binary classification model where we predict for each record, We had to do a small adjustment to account for the records with 2 claims, but youll have to wait to part II of this blog to read more about that, are records which made at least one claim, and our, are records without any claims. Figure 4: Attributes vs Prediction Graphs Gradient Boosting Regression. BSP Life (Fiji) Ltd. provides both Health and Life Insurance in Fiji. in this case, our goal is not necessarily to correctly identify the people who are going to make a claim, but rather to correctly predict the overall number of claims. All Rights Reserved. Predicting the Insurance premium /Charges is a major business metric for most of the Insurance based companies. In the next part of this blog well finally get to the modeling process! Many techniques for performing statistical predictions have been developed, but, in this project, three models Multiple Linear Regression (MLR), Decision tree regression and Gradient Boosting Regression were tested and compared. The effect of various independent variables on the premium amount was also checked. Reinforcement learning is class of machine learning which is concerned with how software agents ought to make actions in an environment. Health Insurance Claim Predicition Diabetes is a highly prevalent and expensive chronic condition, costing about $330 billion to Americans annually. Whats happening in the mathematical model is each training dataset is represented by an array or vector, known as a feature vector. Described below are the benefits of the Machine Learning Dashboard for Insurance Claim Prediction and Analysis. Management Association (Ed. To demonstrate this, NARX model (nonlinear autoregressive network having exogenous inputs), is a recurrent dynamic network was tested and compared against feed forward artificial neural network. Now, lets understand why adding precision and recall is not necessarily enough: Say we have 100,000 records on which we have to predict. for the project. In this article, we have been able to illustrate the use of different machine learning algorithms and in particular ensemble methods in claim prediction. DATASET USED The primary source of data for this project was . Various factors were used and their effect on predicted amount was examined. Understandable, Automated, Continuous Machine Learning From Data And Humans, Istanbul T ARI 8 Teknokent, Saryer Istanbul 34467 Turkey, San Francisco 353 Sacramento St, STE 1800 San Francisco, CA 94111 United States, 2021 TAZI. thats without even mentioning the fact that health claim rates tend to be relatively low and usually range between 1% to 10%,) it is not surprising that predicting the number of health insurance claims in a specific year can be a complicated task. Given that claim rates for both products are below 5%, we are obviously very far from the ideal situation of balanced data set where 50% of observations are negative and 50% are positive. For predictive models, gradient boosting is considered as one of the most powerful techniques. This can help a person in focusing more on the health aspect of an insurance rather than the futile part. Fig. Insurance Claim Prediction Using Machine Learning Ensemble Classifier | by Paul Wanyanga | Analytics Vidhya | Medium 500 Apologies, but something went wrong on our end. Some of the work investigated the predictive modeling of healthcare cost using several statistical techniques. These claim amounts are usually high in millions of dollars every year. Machine learning can be defined as the process of teaching a computer system which allows it to make accurate predictions after the data is fed. Two main types of neural networks are namely feed forward neural network and recurrent neural network (RNN). Most of the cost is attributed to the 'type-2' version of diabetes, which is typically diagnosed in middle age. 1 input and 0 output. Keywords Regression, Premium, Machine Learning. In the past, research by Mahmoud et al. The data included some ambiguous values which were needed to be removed. (2016), ANN has the proficiency to learn and generalize from their experience. How can enterprises effectively Adopt DevSecOps? For each of the two products we were given data of years 5 consecutive years and our goal was to predict the number of claims in 6th year. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. So, without any further ado lets dive in to part I !
