Question
MP/H Rules/Histology--Urinary System: What is the histology code for a 2007 and later diagnosis of papillary carcinoma of the urinary system organs? See Discussion.

Discussion
Will histology code 8050 [papillary carcinoma, NOS] be used for cases diagnosed 2007 and later? The MP/H Rule H4 for urinary primaries states to code papillary carcinoma to code 8130, but Rule M6 includes tumors coded to 8050.

The IARC publication Pathology and Genetics of Tumours of the Urinary System and Male Genital Organs uses code 8130 only for papillary carcinoma.

Answer
Code the histology to 8130 [papillary transitional cell carcinoma] for cases of papillary carcinoma of the urinary system diagnosed 2007 and later.

Histology code 8050 [papillary carcinoma, NOS] should not be used for papillary carcinoma of the urinary system diagnosed starting in 2007. Rule M6 includes this histology to take pre-2007 cases into consideration.
