Senior Fullstack Engineer

About Anomaly

Founded in 2020, Anomaly uses AI and healthcare transaction data to decode complex payer behavior and close the knowledge gap between providers and payers. Our AI engine, Smart Response, analyzes hundreds of millions of healthcare encounters in real time to detect shifting payer rules and denial patterns. By continuously adapting to payer logic, it helps providers predict denials, reverse revenue loss, and hold payers accountable.

 

Our Products and Stack

Anomaly builds a suite of machine learning and analytics products designed to uncover health insurance company payment patterns. Our products include:

• Detect - a web front-end product to surface newly discovered insurance payment patterns and behavior changes utilizing time-series analyses.

• Predict - high-throughput API for machine-learning-powered claim denial prediction with configuration and monitoring live in the web front-end.

• Recover - an analytics-driven product to prioritize denied accounts in order to assist our clients in denial recovery using algorithmic ranking and recommended actions that are fine-tuned towards high-dollar denial reversals.
