Question:

Diagnostic Confirmation: How is Diagnostic Confirmation coded for malignancies diagnosed by a FoundationOne Liquid biopsy/assay involving circulating tumor DNA in blood only? See Discussion.

Discussion:

Example: FoundationAct assay of circulating tumor DNA in blood sample results: Tumor type = non-small cell lung carcinoma, NOS, with 3 genomic alterations identified: NRAS Q61H, IDH2 R140Q and TP53 V172F. The tumor was identified on imaging and the imaging findings were not clearly what one would expect to see with a SCLC.

Answer:

Code Diagnostic Confirmation as 7, Radiology and other imaging techniques without microscopic confirmation for this case. Results of a FoundationOne Liquid biopsy/assay are not specific enough to diagnose this lung malignancy.
