Inquiry Details
References:
2010 SEER Manual, 73-76
Question:
Grade--Kidney, renal pelvis: How is this field coded for a non-invasive high grade papillary urothelial carcinoma of the renal pelvis? See Discussion.
Discussion:
Per instructions in the 2010 SEER Manual, Appendix C, Coding Guidelines for Bladder, "Code grade 9 (unknown) for non-invasive urothelial (transitional) tumors." The Coding Guidelines listed under Renal Pelvis, Ureter are only for Kidney [C649]. Do the grade instructions under bladder apply to ALL non-invasive urothelial tumors, or are we to use the kidney grading instructions to code grade for renal pelvis and ureter malignancies?
Answer:
Code grade to 4 [high grade]. Follow the instructions in the main part of the 2010 SEER Manual under the data item Grade (pages 73 - 76). There are no specific instructions for coding grade for renal pelvis. Apply the general instructions in the absence of site-specific instructions.
