d. The patient's medical records were tampered with.

Health insurance fraud covers a variety of unethical practices including false claims, billing for unprovided services, and intentional misdiagnosis, causing significant economic and trust damage within the healthcare system.

Explanation:

In health insurance, fraud can be contested in multiple situations, including when:

The claim contains false or misleading information.
The medical services were not actually provided.
The provider billed for a more expensive procedure than what was actually performed.
The patient's medical records were tampered with.
The provider intentionally misrepresents the patient's diagnosis.

Health fraud significantly undermines the integrity of the healthcare system, leading to a substantial financial burden on both public and private insurance entities. It encompasses a wide range of unethical practices, from billing for non-existent services (“ghost patients”) to the intentional misdiagnosis of patients for financial gain. The consequences of such actions can extend beyond economic damage, delaying critical care for individuals in need and eroding trust in healthcare professionals.
