Healthcare fraud in the United States includes both unintentional accounting errors and high-value false claims for services never rendered. Experts estimate costs from fraud to be 3-5% of total costs, with billing errors as high as 21%. Common fraud/error scenarios include providers billing patients for services never rendered, double billing, unbundling, and coding errors. Patients can reduce healthcare fraud by double-checking their bills, but many patients struggle to understand complicated insurance billing and payment. Accountants in healthcare settings must focus on recognizing and preventing fraud in their institutions. Reducing fraud depends on patients and accounting professionals monitoring and understanding billing and payments. Healthcare costs will continue to rise, but preventing fraud and errors will reduce the impact of cost increases in the long run.
