Technical Assessment

Published 07/20/2026

To determine compliance with a policy, a Technical Assessment (TA) is required for molecular assays that are laboratory developed tests (LDT). During the TA period, developers should suspend claims submission for the test service. Before submitting a TA, labs must register a test and obtain a unique identifier through the DEX® Diagnostics Exchange.

In order to receive favorable review results, the assay must demonstrate clinical utility (CU), fulfill the CMS "reasonable and necessary" criteria, and meet analytical and clinical validity (AV/CV) standards.

In order to reduce delays and unfavorable determinations, please ensure that the TA submission is complete. Select the link below for specific instructions on how to submit all required documentation for a TA.
