Collaborative Stage

Note 1: Record the number of prostate core biopsies positive for cancer documented in the pathology report. Do not make any assumptions on the number of cores positive based on the number of anatomic locations biopsied because often several cores are submitted per site. If the number of cores positive is not specifically documented, code 991.
Note 2: If multiple needle core biopsy procedures are performed within the timing rule, do not add the positive cores together from the separate procedures. Record the number of cores positive for cancer from the procedure with the highest number positive.
