Neoplasm of uncertain behavior of prostate

This code signifies a prostatic lesion where the pathologist cannot definitively classify it as benign or malignant based on current microscopic examination. It indicates an abnormal growth with some features suggestive of malignancy, but insufficient evidence for a definitive cancer diagnosis.

Apply this code when pathology reports describe a prostate biopsy or surgical specimen as "atypical," "proliferative lesion of uncertain malignant potential," or "neoplasm of uncertain behavior." It is used when the physician has not yet determined the definitive nature of the prostate mass.

• Do not use this code if the pathology report definitively states benign prostatic hyperplasia (BPH) or adenocarcinoma of the prostate.
• If subsequent pathology definitively diagnoses malignancy, update the diagnosis to the appropriate C-code.
• Ensure the documentation clearly states "uncertain behavior" or similar terminology for the prostate lesion.
