Which of the following is considered a best practice for assessing medical necessity?

Performing a denial root cause analysis is considered a best practice for assessing medical necessity because it involves a thorough examination of the reasons behind insurance claim denials. This analysis helps healthcare organizations identify patterns or recurring issues related to medical necessity criteria and can inform strategies to improve compliance with insurance regulations and standards. By understanding the root causes of denials, organizations can adjust their processes, enhance documentation, and ensure that the services provided meet the criteria for medical necessity. This proactive approach ultimately leads to better patient care, less financial loss due to denied claims, and improved overall operational efficiency in the healthcare setting.
