ICD-10 Code C62.1 – Malignant neoplasm of descended testis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C62.1 – Malignant neoplasm of descended testis
What it is
This code identifies a malignant tumor arising in a testis that is normally located in the scrotum. Use it when the documentation specifies the testis is descended and the neoplasm is primary and malignant.
Clinical signs
Common findings include a painless testicular mass, enlargement, or heaviness. Clinical features vary; refer to documentation and pathology or imaging when available.
When to use this code
Use C62.1 when the provider documents primary cancer of a descended testis, including confirmed testicular malignancy in the scrotal position. It may also support coding after biopsy, orchiectomy, or imaging when the diagnosis is clearly stated. Check documentation if laterality or histology affects reporting.
Do not use for
Do not use this code for undescended testis, benign testicular masses, or metastatic disease to the testis. If the record does not clearly state a malignant neoplasm of a descended testis, check documentation.
Coding tip
Confirm the testis is descended and the neoplasm is primary before assigning C62.1.
