Broad coverage, inclusive of all previously covered Signatera indications

Natera, Inc. (NASDAQ:NTRA), a global leader in cell-free DNA and precision medicine, today announced that its genome-based Signatera MRD assay is now covered by Medicare under LCD L38779.

This coverage decision applies to Medicare beneficiaries with colorectal cancer, breast cancer, bladder cancer, ovarian cancer, lung cancer, and pan-cancer immunotherapy monitoring, mirroring the pre-existing coverage for Signatera.

The coverage determination was supported by robust evidence on the validity of the genome-based assay, leveraging the extensive body of literature validating Signatera in over 100 published clinical studies.

Earlier this week at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, Natera presented a pan-cancer study of 392 patients (over 2,600 samples) using Signatera Genome. The assay was launched recently for both research and clinical use. It leverages Natera's patented and proven multiplex PCR-NGS (mPCR) technology, which allows for deep sequencing of targeted high-quality variants.

"We are pleased to have Medicare coverage now in place for our genome-based Signatera assay, underscoring the clinical utility of our test, as well as its analytical and clinical validity," said Matthew Mega, senior vice president of market access. "This allows Medicare patients broader access to the latest innovations in our MRD product portfolio."
