The phenomenon of Fee Splitting, or the unethical and illegal division of fees between physicians and other healthcare providers, represents a significant challenge in professional medical ethics. This practice, often driven by the desire to attract more patients or increase financial gain, carries serious ethical, legal, and social consequences. This paper aims to explore various dimensions of Fee Splitting, beginning with its definition and typologies, followed by an analysis of its implications. It also examines global approaches to address this issue, including stringent regulations in the United States, transparent reporting systems in the United Kingdom, and the use of technology in Singapore. In Iran, despite laws prohibiting this practice, weak enforcement and economic pressures have contributed to its persistence in certain segments of the healthcare system. Insights from successful global experiences suggest that implementing transparent oversight systems, leveraging artificial intelligence to detect violations, and promoting ethical professional practices through education can play a critical role in mitigating Fee Splitting. The paper also presents practical strategies to prevent and combat Fee Splitting in Iran. These strategies include strengthening regulatory frameworks, educating physicians on professional ethics, utilizing advanced technologies to monitor financial transactions, and introducing clear and lawful financial incentives. Furthermore, the importance of fostering cultural change and reshaping public perceptions within the medical community is emphasized. The findings of this study underscore that addressing Fee Splitting as a serious ethical challenge requires a shared commitment from physicians, policymakers, and society at large. By reforming oversight structures, prioritizing education, and employing innovative tools, a more transparent healthcare system can be established, enhancing trust within the medical profession.
