Uses Neo4j graph databases, Cypher queries and Jupyter Python notebooks to link prescriptions, providers and pharmacies and detect fraud rings; Neo4j runs community detection, centrality and path algorithms to flag outliers like a pharmacy with 42% of patients living >500 miles away and a doctor whose eight patients died yet kept prescribing. Public datasets (ARCOS) and graph-enhanced ML feed into Cypher on Spark for fast entity resolution and patient 360. Technique breaks real rings (Seattle case, Panama Papers leads to prosecutions) and scales to millisecond decision windows.
