headline: Next-Generation Machine Learning in Healthcare Fraud Detection: Current Trends, Challenges, and Future Research Directions
dek: The growing complexity and size of healthcare systems have rendered fraud detection increasingly challenging; however, the current literature lacks a holistic view of the latest machine learning (ML) techniques with practical implementation concerns. The present study addresses this gap by highlighting the importance of machine learning (ML) in preventing and mitigating healthcare fraud, evaluating recent advancements, investigating implementation barriers, and exploring future research dimensions. To further ad…
gain_title: Machine learning approaches including supervised, unsupervised, deep learning and hybrid methods improve prevention and detection of healthcare fraud in large, imbalanced datasets.
problem_title: Employing machine learning for healthcare fraud detection is limited by poor data quality, scalability issues, regulatory compliance requirements, and resource constraints.
trace_subject: machine learning for healthcare fraud detection
gain_reading: Machine learning approaches including supervised, unsupervised, deep learning and hybrid methods improve prevention and detection of healthcare fraud in large, imbalanced datasets.
gain_evidence: highlighting the importance of machine learning (ML) in preventing and mitigating healthcare fraud | enhancing fraud detection in imbalanced and multidimensional datasets
problem_reading: Employing machine learning for healthcare fraud detection is limited by poor data quality, scalability issues, regulatory compliance requirements, and resource constraints.
problem_evidence: challenges of employing machine learning (ML) in healthcare systems, including data quality, system scalability, regulatory compliance, and resource constraints
quick_read: Published August 25, 2025, this peer-reviewed review synthesized current machine learning methods for healthcare fraud detection, covering supervised, unsupervised, deep learning, and hybrid approaches like SMOTE-ENN, explainable AI, federated learning, and ensemble learning, and noted Medicare, LEIE, and Kaggle as common evaluation datasets.

The work matters because it links technical advances to implementation needs for payers and providers, pointing to interpretability for compliance and federated learning for confidential sharing, while uncertainty remains around how to overcome data quality, scalability, regulatory, and resource constraints in operational, real-time systems.
limitation: Real-world deployment is constrained by data quality, system scalability, regulatory compliance, and resource constraints in healthcare systems.
tag: Automated dual reading
key_points: Study reviewed supervised ML, unsupervised ML, deep learning, and hybrid approaches such as SMOTE-ENN, explainable AI, federated learning, and ensemble learning. | Commonly employed evaluation datasets identified were Medicare, the List of Excluded Individuals and Entities (LEIE), and Kaggle datasets. | Actionable insights highlighted were model interpretability to enable regulatory compliance and federated learning for confidential data sharing for policymakers, providers, and insurers.
rundown: The review considered a broad spectrum of techniques to address imbalanced and multidimensional claims data, specifically naming SMOTE-ENN, explainable AI, federated learning, and ensemble learning alongside standard supervised and unsupervised methods.

It identified Medicare, LEIE, and Kaggle datasets as baselines for model evaluation and proposed a framework for real-time detection through self-learning, interpretable, and safe ML infrastructures integrating theoretical advances with practical needs.
