Question:

Solid Tumor Rules/Histology--Ovary: How is histology coded for an ovary case with a diagnosis of “high grade papillary serous carcinoma” in 2023? This term is not in the Solid Tumor Rules and ICD-O 3.2 updates. Is “high grade papillary serous carcinoma” equivalent to “high grade serous carcinoma” (8461) or to “papillary serous adenocarcinoma” (8441) with high grade captured only in the Grade fields, or is there another more appropriate code?

Discussion:

Answer:

Assign code 8461/3 for high-grade papillary serous carcinoma.
