Scenario: 2024 RIGHT KIDNEY NEPHRECTOMY: -CLEAR-CELL PAPILLARY RENAL CELL CARCINOMA
Question: How would you code histology?
- 8260 Papillary renal cell carcinoma (C64.9)
- 8312 Renal cell carcinoma
- 8310 Clear cell renal cell carcinoma
- 8323 Mixed cell adenocarcinoma
Answer: 8323 Mixed cell adenocarcinoma
Rationale:
Remember to always start with the Solid Tumor Rules when coding histology, not your drop-down menu.
Solid Tumor Rules Kidney 2024 Update
Rule H1 Code the histology when only one histology is present. Note 1: Use Table 1 to code histology. New codes, terms, and synonyms are included in Table 1 and coding errors may occur if the table is not used.
Informational Item: WHO 4th edition Tumors of the Urinary System has proposed ICD-O code 8323/1 for clear cell papillary renal cell carcinoma. This has not been approved for implementation by the standard setters in 2018. This change has NOT yet been implemented and it remains reportable.
