Question:

Reportability/History (Pre-2007)/Behavior Code--Ovary: Should the matrix principal in Rule F be applied to code a 2002 right ovary case to 8462/3 [Papillary serous borderline ovarian tumor] when peritoneal washings reveal the same histology?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Do not apply the matrix principle in this case. This ovarian tumor is not reportable (behavior /1 per ICD-O-3). The peritoneal washings reveal the same histology (/1), rather than malignant cells. Based on the information provided, there is no evidence to support changing the behavior code.

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.
