Grade Path Value

Field Length:  1

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

This field documents the numerator or first number of a tumor grade reported in a 2, 3, or 4 grade system.  It is paired with Grade Path System (item #30132) 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)

• Code the histologic grade in priority over a nuclear or architectural grade.

• Do not convert the terms well, moderately, or poorly differentiated, low/high, or anaplastic into codes in this field.  Leave blank if those terms are the only available grade information.  

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

• 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 System (item #30132) should both be coded or both be blank.  If both are coded, Tumor Grade (item #30130) must not be 9.  Grade Path Value can never be larger than Grade Path System.
