Question:

Histology (Pre-2007)--Kidney: What code is used to represent the histology "renal cell carcinoma with granular cell morphology"? Kidney primary with diagnosis of renal cell CA with granular cell morphology. Do we code as granular cell carcinoma? Is the term "morphology" synonymous with "type"? See discussion.

Discussion:

Do we code this type of tumor as a granular cell carcinoma [8580/3]?

Answer:

For tumors diagnosed prior to 2007:

Code the Histology field to 8320/3 [granular cell carcinoma]. Renal cell carcinoma is a non-specific term that has several specific cellular subtypes, one of which is granular cell [8320/3].

Note: Do not code to granular cell tumor [9580/3], which is not a histology related to renal cell carcinoma.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
