ICD-10 Code C62 – Malignant neoplasm of testis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C62 – Malignant neoplasm of testis
What it is
C62 identifies a malignant tumor arising in the testis. Use it when documentation states testicular cancer or a primary malignant neoplasm of the testis.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include a painless testicular mass, swelling, heaviness, or discomfort, with diagnosis confirmed by imaging and pathology.
When to use this code
Use C62 when the provider documents a primary malignant neoplasm of the testis, including a confirmed testicular cancer diagnosis. Code it from pathology, operative, or oncology notes when the site is clearly identified. If laterality or histology is documented, capture those details separately when instructed.
Do not use for
Do not use C62 for benign testicular masses, epididymal disease, or secondary malignant neoplasms involving the testis. Check documentation if the record only says “testicular lesion” or “rule out cancer.”
Coding tip
Verify that the neoplasm is primary to the testis before assigning C62.
