Neoplasm of uncertain behavior of other and unspecified male genital organs

This code signifies a tumor of the male reproductive system whose biological behavior (benign or malignant) cannot be definitively determined from pathological examination. It applies to growths in male genital organs other than the testes, prostate, epididymis, or spermatic cord, which have their own specific codes.

Use this code when pathology reports indicate a neoplasm of uncertain behavior in sites such as the penis, seminal vesicles, or vas deferens. Documentation must clearly state the uncertain nature of the tumor and its specific location within the "other and unspecified male genital organs" category.

• Differentiate carefully from neoplasms of uncertain behavior of the testis (236.5) or prostate (236.4).
• Ensure the pathology report explicitly uses terms like "uncertain behavior," "borderline malignancy," or "indeterminate."
• Avoid using this code if the neoplasm is definitively diagnosed as benign or malignant; use the appropriate benign or malignant neoplasm code instead.
