HEADER | ******Determine Grade/Differentiation/Cell Type****** |
TEXT | Code the degree of differentiation or grade stated in the FINAL pathologic diagnosis only. For example: Microscopic Description: Moderately differentiated squamous cell carcinoma with poorly differentiated areas Final Pathologic Diagnosis: Moderately differentiated squamous cell carcinoma Grade, differentiation Code to the final diagnosis: Moderately differentiated '2'. Usually there will be no statement as to grade for in situ lesions. However, if a grade is stated, it should be coded. When there is variation in the usual terms for degree of differentiation, code to the higher grade as specified below: TERM GRADE CODE ====================== Low grade I-II 2 Medium grade II-III 3 High grade III-IV 4 Partially well differentiated I-II 2 Moderately undifferentiated III 3 Relatively undifferentiated III 3 Grade coding for prostate cases using Gleason's score or pattern. 1. If Gleason's score (2-10) is given code as follows: Gleason's score Grading 2, 3, 4 I Well Differentiated 5, 6, 7 II Moderately Differentiated 8, 9, 10 III Poorly Differentiated 2. If Gleason's pattern (1-5) is given code as follows: If a diagnosis indicates two different degrees of grade or Gleason's pattern Grading 1-2 I Well Differentiated 3 II Moderately Differentiated 4-5 III Poorly Differentiated For lymphomas and leukemias designation of T-cell, B-cell, and null cell: ======================================================================== Code the results of marker studies. Code the final pathologic diagnosis of T-cell, B-cell or null cell if marker studies are not documented differentiation (e.g. "well and poorly differentiated"; or "grade in the patient record. (See page 2 of ICD-O, FT, 1987.) For lymphomas and leukemias, information on T-cell, B-cell or null cell has precedence over information on grading or differentiation. II-III"; or "well differentiated grade II"), code to the higher grade code (Rule 10, page xxxi in ICD-O, 1990). |
