ICD-10 Code C62.10 – Malignant neoplasm of unspecified descended testis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C62.10 – Malignant neoplasm of unspecified descended testis
What it is
This code identifies a malignant tumor in a testis that is known to be descended, but the side is not specified in the record. Use it when the documentation confirms testicular cancer without laterality detail.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a painless testicular mass, swelling, or heaviness, but the diagnosis is usually confirmed by imaging, pathology, or specialist evaluation.
When to use this code
Use C62.10 when the provider documents malignant neoplasm of a descended testis and does not specify right or left. It also fits when laterality is unavailable in the final diagnosis or operative report. Check documentation if the record instead describes an undescended testis or another scrotal mass.
Do not use for
Do not use this code for benign testicular lesions, nonmalignant masses, or cancer of an undescended testis. If the side is documented, choose the laterality-specific code instead.
Coding tip
Verify both malignancy and laterality in the final provider note before assigning C62.10.
