Inquiry Details

2014+ Grade Instructions
Question:
Grade--Bladder: Do you use the grade stated on the pathology report for coding the grade/differentiation field for bladder and renal pelvis field? See discussion.
Discussion:
Please confirm correct coding for grade for papillary urothelial carcinoma of the bladder/renal pelvis and urothelial carcinoma of the bladder/renal pelvis. SEER Manual 2014 and 2015 state: "Do not use these tables to code grade for any other groups including WHO (CNS tumors), WHO/ISUP (bladder, renal pelvis), or FIGO (female gynecologic sites) grades." They also state "In transitional cell carcinoma for bladder, the terminology high grade TCC and low grade TCC are coded in the two-grade system" in the Grade section. These statements are not included in SEER Manuals prior to 2014.
Answer:
Use the grade stated on the pathology report to code grade/differentiation for bladder and renal pelvis field unless the grade is stated to be WHO/ISUP grade.
