2025 ICD-10-CM code C63.8
Effective Date: N/A Neoplasms - Malignant neoplasms of male genital organs Chapter 2: Neoplasms Feed
Malignant neoplasm of overlapping sites of male genital organs. Primary malignant neoplasm of two or more contiguous sites of male genital organs whose point of origin cannot be determined.
Medical necessity for treatment related to C63.8 is established by the diagnosis of a malignant neoplasm.The specific treatment provided must be consistent with established guidelines for cancer care.
Clinicians responsible for diagnosing and managing this condition include urologists, oncologists, and potentially other specialists depending on the specific organs involved and the extent of the disease.Diagnosis involves physical examination, imaging studies (CT, MRI, PET), biopsy, and potentially cystoscopy or proctoscopy. Treatment may involve surgery, radiation therapy, chemotherapy, or a combination of these modalities.
In simple words: This code refers to cancer affecting multiple, adjacent parts of the male genitals when doctors can't pinpoint exactly where the cancer started.
This code represents a primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites of the male genital organs.It is used when the point of origin of the malignancy cannot be determined.The male genital organs include the penis, scrotum, testes, epididymis, vas deferens, seminal vesicles, prostate, and other accessory glands.
Example 1: A patient presents with a large mass involving the scrotum and the base of the penis. Biopsy confirms malignancy, but it is unclear whether the tumor originated in the scrotal skin or the penile skin. C63.8 is assigned., A patient with a history of cryptorchidism develops a malignant tumor involving the right testis and the adjacent spermatic cord. The primary site is undetermined. C63.8 is applied., A malignant neoplasm is found to involve both the prostate and the left seminal vesicle, with no clear evidence of which site was the origin. C63.8 is the appropriate code.
Documentation should clearly describe the size, location, and characteristics of the tumor, the organs involved, and the results of any diagnostic procedures performed. The ambiguity regarding the point of origin must be explicitly stated.
