Question:

EOD-Size of Primary Tumor--Prostate: When there are multiple nodules in the prostate, can size of tumor be based on the size of the largest nodule? See discussion.

Discussion:

Rectal exam: Prostate enlarged, nodular and irregular. No masses. Pathology from prostatectomy: Focal nodules measuring up to 1.3 cm in diameter. Moderately differentiated adenocarcinoma. Would tumor size be 013 or 999?

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Size of Primary Tumor field to 013 [1.3 cm]. Code the size of a mass or nodule only when there is pathologic confirmation of malignancy. In the case you mention, the nodules were pathologically confirmed as cancer, so you would code the size of the largest nodule. If a nodule/or mass in the prostate is confirmed as cancer by needle biopsy, you would code the size of the mass or nodule.
