Malignant neoplasm of testis (C62) ICD-10-CM
The C62 code range covers malignant neoplasm of testis with 13 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the C62 range.
Malignant Testicular Neoplasm
A primary or metastatic malignant neoplasm that affects the testis. Representative examples include malignant germ cell tumors, sarcomas, leukemias, and lymphomas.
Seminoma
A radiosensitive, malignant neoplasm of the testis, thought to be derived from primordial germ cells of the sexually undifferentiated embryonic gonad. There are three variants: classical (typical), the most common type; anaplastic; and spermatocytic. The classical seminoma is composed of fairly well differentiated sheets or cords of uniform polygonal or round cells (seminoma cells), each cell having abundant clear cytoplasm, distinct cell membranes, a centrally placed round nucleus, and one or more nucleoli. In the female, a grossly and histologically identical neoplasm, known as dysgerminoma, occurs. (Dorland, 27th ed)
About the C62 Code Range
These codes describe cancer affecting a testicle, whether it starts there or spreads there from elsewhere.
The categories separate an undescended testicle (C62.0), a descended testicle (C62.1), and a testicle whose descent status is unspecified (C62.9). Each group then distinguishes the right testicle, the left testicle, or an unspecified testicle.
