Question:

Grade, Differentiation--All Sites: If the grade given for the primary site is from a provisional diagnosis and the grade given for a metastatic site is from a final diagnosis, should we follow the SEER rule that says to code the grade as stated in the final diagnosis (e.g., Provisional diagnosis: High grade papillary serous carcinoma of ovary. Final dx: poorly differentiated adenocarcinoma in a caval lymph node)?

Discussion:

Answer:

Code the Grade, Differentiation field to 4 [High grade] from the examination of the ovary (primary site). Do not code grade from a metastatic site.
