FoundationOne CDx / Liquid CDx

The FDA-approved tissue (324 genes) and blood genomic tests that serve as companion diagnostics for dozens of drugs.

FoundationOne CDx and Liquid CDx are Foundation Medicine's (Roche) comprehensive genomic profiling tests. They report mutations, CNVs, fusions, TMB, MSI, and (tissue) HRD-LOH. Companion diagnostic for >30 therapies including olaparib, capivasertib, T-DXd (HER2 in NSCLC), and selpercatinib.

Medicare
Part B (clinician-administered)NCD 90.2

Covered nationally under NCD 90.2 as an FDA-approved companion diagnostic NGS test for patients with recurrent, relapsed, refractory, metastatic or advanced stage III/IV cancer who have not previously had the same test for the same primary cancer. Laboratory tests under Part B have no coinsurance.

Commercial insurance
variable

Most large commercial plans cover comprehensive genomic profiling for advanced NSCLC and increasingly for other advanced solid tumours, with prior authorisation; some limit panel size or require a specific lab.

No Part B coinsurance on clinical laboratory tests. Foundation Medicine offers a patient assistance programme for out-of-pocket costs.

Notes
NHS England does not commission commercial CGP panels routinely; tumour profiling is delivered by the seven NHS Genomic Laboratory Hubs under the National Genomic Test Directory, including whole genome sequencing for some cancers. Commercial panels may be obtained privately.
