Natera, Inc. announced the assignment of two Z-codes for the company's Signatera test, in preparation for its planned clinical launch in second quarter of 2019. Signatera, when clinically available, is intended for use by oncologists to detect molecular residual disease (MRD) and monitor treatment response in cancer patients. Two Z-codes were awarded, ZB8DC and ZB8DD, representing the initial and subsequent test orders for each patient. These codes will cover multiple cancer types, as the Signatera technology has shown consistent performance across multiple cancers, including lung, breast, colorectal, and bladder.
