Which of the following best defines fraud in healthcare?

Fraud in healthcare involves the intentional deception or misrepresentation that results in unauthorized benefits or payments. Charging for unnecessary tests that were not needed exemplifies this deception, as it reflects an intention to defraud the payer by billing for services that have no legitimate medical necessity. This kind of action not only violates ethical standards but also undermines the integrity of the healthcare system, causing financial harm to both insurers and patients.

In contrast, submitting claims for services that were actually provided does not constitute fraud, as it reflects legitimate transactions. Providing patients with correct and clear information is contrary to fraudulent practices and is essential for ethical healthcare delivery. Lastly, accidentally misfiling health insurance claims typically falls under errors or mistakes in billing rather than a deliberate fraudulent act. Therefore, the best definition of fraud in healthcare, in this context, is indeed the act of charging for unnecessary tests that were not needed.
