*** This data item was discontinued effective 01/01/2014***

This field documents the denominator or second number of a tumor grade reported in a 2, 3, or 4 grade system.  This item is used in conjunction with Grade Path Value (item #30131) to describe the original grade of the tumor.  It may be left blank for cases diagnosed prior to January 1, 2010

Instructions for Coding

  • Code this item from the same tissue as that used to code Tumor Grade (item #30130)

  • If grade is described in the medical record as a fraction (x/y), this field is the denominator.  In other words, this field is the second or lower number of a grade expressed in two parts.  

  • Leave this item blank if no pathologic grade is available

  • Leave this item blank if only a verbal description of grade is reported (i.e., moderately differentiated)

  • Leave this item blank if another grading system is used in the pathology report.  For example, do not report grading systems such as Bloom-Richardson for breast primaries, Fuhrman for kidney, Gleason for prostate, or WHO grade.  Those grading systems are coded in a site-specific factor for the applicable CS schema.

  • Leave this item blank for lymphomas and hematopoietic malignancies (9590-9992)

  • This item and Grade Path Value (item #30131) should both be coded or both be blank.  If both are coded, Tumor Grade (item #30130) must not be 9.
