Administrative Aspects of Molecular Diagnostics-Oversight, Regulatory Approval Process, Clinical and Operational Workflows, and Payment Models.

This paper discusses the administrative aspects of molecular diagnostics in oncology, including US Food and Drug Administration (FDA) oversight, the regulatory approval process, clinical, and operational workflows, and payment models. Comprehensive molecular testing is important to deliver optimal oncology care and improve patient outcomes. Despite the potential benefits of testing, utilization remains low. The FDA regulatory approval process is reviewed for in vitro diagnostic products, which includes classification into three regulatory classes on the basis of risk. Companion diagnostic devices are used to guide treatment decisions. The clinical and operational challenges associated with molecular testing in oncology are also discussed, including the rapidly evolving landscape of precision oncology, the wide range of biomarker testing options, and complexities of test ordering, interpretation, and result delivery. There is a need for a multifaceted support approach involving education, technology enhancements, and workflow support to overcome these challenges. In terms of payment models, coverage policies between Medicare and commercial payers are compared with differences in coverage criteria, with Medicare focusing on FDA approval or clearance, whereas commercial payers consider additional factors such as National Comprehensive Cancer Network and ASCO guidelines. Commercial payers tend to cover smaller panels on the basis of guideline-recommended biomarkers, whereas coverage for broad tumor profiling is limited. Several strategies can increase the utilization of molecular testing, including integrating test results into electronic medical record platforms, standardizing billing practices, increasing clinical trials, and primary literature supporting the use of molecular testing, educating physicians, and using tumor boards for result interpretation and treatment discussions.
