ICD-10 Code C62.01 – Malignant neoplasm of undescended right testis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C62.01 – Malignant neoplasm of undescended right testis
What it is
This code identifies a malignant tumor arising in the right testis when that testis has not descended into the scrotum. Use it for a documented cancer specifically located in an undescended right testis.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a palpable inguinal or abdominal mass, absent right testis in the scrotum, or imaging and pathology confirming malignancy in the undescended testis.
When to use this code
Use C62.01 when the provider documents primary malignant neoplasm of the undescended right testis. It is appropriate after imaging, surgery, or pathology confirms the site and laterality. Check documentation if the record only states testicular cancer without specifying an undescended right testis.
Do not use for
Do not use this code for benign testicular masses, unspecified testicular cancer, or malignancy in the left testis. If the tumor site is not clearly documented as the undescended right testis, check documentation.
Coding tip
Confirm both laterality and undescended status in the operative note, pathology report, or problem list before assigning C62.01.
