Medicare Local Coverage Determinations for Genetic Testing
Medicare Technical Assessment for Molecular Assays
To determine coverage for genetic test Medicare LCD, the Centers for Medicare and Medicaid (CMS) requires a Technical Assessment (TA) for molecular assays that are laboratory developed tests (LDT). LDTs :
- utilize Next Generation Sequencing (NGS) technology,
- utilize new or novel technology, or
- have undefined or unproven clinical utility
During the TA period, test developers are requested by CMS to suspend submission of claims for the test. Before submitting a TA, a Medicare Administrative Contractor (MAC) such as Palmetto GBA may require that a lab register a test and obtain a unique identifier through the DEX Registry.
Medicare LCD development
The MAC may require that the assay must have :
- clinical utility (CU),
- fulfill the CMS “reasonable and necessary” criteria, and
- meet analytical and clinical validity (AV/CV) standards.
In addition to the ACCE criteria developed by the Centers for Disease Control and Prevention.
Medicare Requires use of ACCE Criteria for Genetic Test Coverage
CMS requests that Medicare LCDs for genetic tests be developed using “ACCE” which stands for:
- analytic validity,
- clinical validity,
- clinical utility,
- ethical, legal, and social implications
ACCE uses four categories for determining Medicare local coverage determinations (LCDs) for a genetic test. The ACCE methodology includes
- data collection,
- evaluation,
- interpretation, and
- reporting
regarding DNA and associated testing for disorders with a genetic component. The methodology enables policymakers to access up-to-date and bioinformatic data for decision-making.
There are forty-four (44) questions:
The ACCE criteria are below:
