Question:

EOD-Extension--Kidney: If a "tumor thrombus" in a renal vein is discontinuous from the primary tumor in the kidney, is it still coded to 60 [Tumor thrombus in a renal vein, NOS], rather than 85 [Metastasis]?

Discussion:

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 60 [Tumor thrombus in a renal vein, NOS]. A thrombus can be a bolus of tumor cells within a large vein that may or may not still be connected/contiguous with the primary tumor. However, both a discontinuous and contiguous thrombus are coded to 60.
