Question:

Multiplicity Counter--Prostate: How is multiplicity counter to be coded for a clinically inapparent prostate cancer for which sextant needle biopsy cores on left and right sides are positive for adenocarcinoma? See Discussion.

Discussion:

Prostate cancer typically presents as multifocal diffuse disease. The coding exercise in the MPH rules presentations coded prostate cancer as one tumor.

Answer:

Code the number of tumors present if known. This information can be taken from any part of the record, including imaging and prostatectomy. If the only information available is "diffuse," or "multifocal," assign code 99. Do not assume there are multiple tumors just beacause there are multiple biopsies. When there is no information about the number of tumors, code Multiplicity Counter to 99 and Type of Multiple Tumors to 99.
