Malignant neoplasm of other and unspecified male genital organs (C63) ICD-10-CM
The C63 code range covers malignant neoplasm of other and unspecified male genital organs with 13 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the C63 range.
Epididymis
The convoluted cordlike structure attached to the posterior of the TESTIS. Epididymis consists of the head (caput), the body (corpus), and the tail (cauda). A network of ducts leaving the testis joins into a common epididymal tubule proper which provides the transport, storage, and maturation of SPERMATOZOA.
Spermatic Cord
Either of a pair of tubular structures formed by DUCTUS DEFERENS; ARTERIES; VEINS; LYMPHATIC VESSELS; and nerves. The spermatic cord extends from the deep inguinal ring through the INGUINAL CANAL to the TESTIS in the SCROTUM.
Spermatic Cord Torsion
The twisting of the SPERMATIC CORD due to an anatomical abnormality that left the TESTIS mobile and dangling in the SCROTUM. The initial effect of testicular torsion is obstruction of venous return. Depending on the duration and degree of cord rotation, testicular symptoms range from EDEMA to interrupted arterial flow and testicular pain. If blood flow to testis is absent for 4 to 6 h, SPERMATOGENESIS may be permanently lost.
Sterilization Reversal
Procedures to reverse the effect of REPRODUCTIVE STERILIZATION and to regain fertility. Reversal procedures include those used to restore the flow in the FALLOPIAN TUBE or the VAS DEFERENS.
Vas Deferens
The excretory duct of the testes that carries SPERMATOZOA. It rises from the SCROTUM and joins the SEMINAL VESICLES to form the ejaculatory duct.
About the C63 Code Range
The ICD-10 code C63 covers malignant tumors found in various less commonly specified male genital organs, such as the epididymis, spermatic cord, scrotum, seminal vesicle, and other related tissues. These codes help healthcare providers document and categorize these rare but serious cancers accurately in medical records and billing.
The section includes specific codes like C63.0 for malignant neoplasm of the epididymis, with subcodes distinguishing right (C63.01) or left side (C63.02), and similar subcategories for spermatic cord cancers (e.g., C63.1, C63.11, C63.12). It also covers cancers of the scrotum (C63.2) and other specified male genital organs such as the seminal vesicle (C63.7). The code C63.9 is used when the malignant neoplasm of a male genital organ is unspecified. For coders and clinicians, recognizing synonyms like "primary carcinoma of epididymis and spermatic cord," "malignant tumor of spermatic cord," or "squamous cell carcinoma of scrotum" is essential when selecting the appropriate ICD-10 code for male genital malignancies. This specificity supports precise diagnosis and treatment documentation in oncology and urology.
